Title: TRWspring, Bilstein shock, Dragvette strut install
Post by yellowJACKet on Feb 7th, 2006 at 6:12pm
TRW spring, Bilstein shock, Dragvette strut installation




NOTE: This whole job took me about 7 hours to do. If you follow the instructions I've laid out, it will save you about three hours of work time, providing it is your first time to attempt this. I've learned several shortcuts and things NOT to do by trial and error.  Should only take 3-4 hours now. I hope this helps someone down the road.

Today I got started installing my TRW Spring, Bilstein shocks and Dragvette struts.

I will add here as I go...

First, I jacked up the Vette and put the Jacks a few inches behind the door frame on both sides: (Note: I don't know how much harder it is to do with the tire carriage cover and rear shocks as I don't have either one back there.)


Then took off both rear tires. I place the jack under the spring bolt to relieve the tension. I then C-clamp the spring so the jack wouldn't slip while I loosened the Spring bolt.


Here is what it looks like after I took the spring bolt out. Quite a drop.


Next, I loosened the 4 big bolts holding the spring to the rear end.


The Spring is out!  :boldpurple: It is heavy too!


Okay, now it was time to remove the L-shape bolt holding both the shock and strut.


After loosening that bolt, I removed the top shock bolt in order to remove the bottom L-shaped bolt holding the shock/strut.


Here is what that L-shape bolt looks like that holds the shock & strut.


Next I went over and removed the bolt holding the strut to the strut bracket.


Yay! :boldpurple: I am now halfway as I got the spring, shocks and struts off.  


Big difference between the stock strut and Dragvette strut.


This took me about three hours. Tomorrow I will get started on installing the new TRW spring, Bilstein shocks & Dragvette struts.

Great job...wish I could have read this before I did mine. Make sure you put some threadlocker on those adjustable struts after you get it alligned...if they come loose you'll have a mess.

Thanks guys! It is gonna be nice once it is done.

I posted a question on the trailing arms, (didn't know it at the time) in the Tech catagory. Now, I have another question. I read somewhere that your not suppose to tighten certain bolts down until AFTER you let the Vette down off the jack stands? Anything to this?

You say After the alighnment? And what do I threadlock, the bolts mounting it to the rearend and to the shock bracket? what about the two adjustable Nuts? Threadlock those too?

I'm going to try to get it done Thursday afternoon... hah! ... more like Friday with my talents. :D :crazy:

Post by Knotacare on Feb 9th, 2006 at 4:05am
Just threadlock the adjustable bolts...I had mine come loose twice after each allignment. I blamed it on the techs, but it's easier to back them off one at a time and apply the threadlock & retighten. Maybe the high hp & tq put a lot of strain & twisting on them. Also after your allignment unless you're allowed to be right there...check all bolts & make sure they're tight. Nobody cares about your car like you do...

Okay, today I got the Shocks and Struts in and ran out of time to put the Spring in.

I installed the Bilstein Shocks at the top first, then at the bottom.
As you can see by the pix, I installed the bottom Shock first before putting the L shape bolt through the strut bracket. MISTAKE! It took me well over an hour to do that. On the other side, I installed the strut bolt in first, then put the shock on, barely. This only took an half hour.


Next I installed the dragvette spacer that goes between the strut bracket and differential, (RED arrows).




The cam bolt is suppose to be set at 6 o'clock. The left is correct, but I have to set the drivers tomorrow as I ran out of time...




Here is what it looks like so far... with TRW spring on the gound waiting to be put in.

Just remember your car needs to settle for awhile & if you can't get the back end down you'll have to go to longer bolts. I ended up using  10" grade 8  bolts. Looks like you're doing a great job & this should answer many question & help lots of people.

Looks like I'm in for a snow storm tomorrow...I'd rather have rain.

The TRW spring came with a longer than stock bolts @ 9" while Dragvette came with the 10" ones.
Boy was I wrong. When I measured the two bolts, the stock one was 7", TRW was 7-1/2" and Dragvette was 8". No good.... I'm still at least 2" too high (4.5" from fender-lip to top-tire). I'm going down to get a 10" bolt and I have to do it all over again. >:(
I will drive it around a bit and see if it settles some first.

Post by yellowJACKet on Feb 10th, 2006 at 5:11pm
Okay, wrapup time... (with exception of having to get two 10" spring bolts to replace the 8" ones).

Today I put in the TRW spring. Unless your VERY strong, it helps to use a jack to hold the spring center in place to start the 4 bolts. There is a heatsheild and cover plate that is bolted with that.


Next was to install the spring bolts. These were tricky and I can save you about an hour of time with the shortcut I learned. Only run the 4 bolts in the center (last pix above) about halfway in so you can jiggle the outer spring a tad in order to get the long spring bolt in the top AND the spring (two red arrows). I tried it with the 4 center bolts all the way in and an hour later still couldn't get that bolt in. Did the other side this way and it only took 10 minutes! You also have to use a jack to move the spring up in order to get the bolt through (bottom red arrow). Be sure NOT to slip the jack off the metal tip or else you'll ruin the spring!


The struts are very easy to adjust. Just use a level on the wheels and turn the two outer nuts on the strut bar (red arrow) and twist the knurled part of bar (yellow arrow) until you get the correct wheel/tire level:


BEFORE:

and AFTER. Not bad, not bad at all! ;D

Thanks! Bear in mind that in addition to what I did, since you have the rear exhaust and tire cover... the exhaust will have to be dropped and tire tire cover and tire removed.

I have the sidepipes and my tire cover assembly has been long removed...

I went to four hardware stores and NAPA warehouse and none of them has any grade 8 bolts longer than 6" :o

Tacoma Screws warehouse was closed this weekend, so I have to wait until Monday. I'm hoping they have one. If not, anybody know online where I can get one?

Alan, where did you get yours?

Title: Re: TRWspring, Bilstein shock, Dragvette strut ins
Post by Knotacare on Feb 12th, 2006 at 10:06am
That's probably going to be hard to find. I have a place called Lilly Fastners down the street from my shop( that's where I got mine) if they don't have it ...then it's not made. If you can't find the bolt let me know & I'll go down & pick up 2 for you. I went with a bigger bolt I think it was a 1/2 or 5/8 X 10". Just let me know what you want. By the way we just got over 12" of snow. Took over 2 hours to clean the cars off,snow blow & shovel. :sweatdrop: Can't wait for spring I'm getting to old for this.

Jack,

Just a couple of things...

I believe the C4 Vettes used a 10" bolt stock. Now to the possible bad news...you will find that the 10" bolts hang below your wheels. If you have a tire go down the car will high center on the too long bolt and could cause all kinds of problems.

If you were running 17 or 18" wheels you would have no problem, but the 15" wheels won't allow the clearance. If you want to double check it just measure where the 8" bolts come down...then add another 2" and you will see what I'm talking about.

Some people have done it, but it can cause serious problems if you have a flat.

Just thought you should be made aware of possible problems.

Good luck,
Jeff :burnout:

Wow! That's scary! Thanks for the tips. I guess I should have gotten the 60 series instead of the 50 series.

Hey Alan, your running 10" bolts... what tires and wheel size are you running? What clearance do you have?

Title: Re: TRWspring, Bilstein shock, Dragvette strut ins
Post by Knotacare on Feb 13th, 2006 at 4:04am
I'm running 8" bolts & the bolt is about 1/2" below the wheel (15"X8"). I did have a flat about 1 yr ago (truck rubber got caught on my rim & broke the valve stem)talk about luck. The bolt never hit because the flat tire gave me enough clearance, probably an inch or 2. I'll shoot a picture & send it to Jack later. So I would have to say you still have about 1" to play with, but its been a few years since I  did my rear suspension, I did buy 10" bolts & they were to long...so went to 8". 10" would probably work with 18" tires. Sorry about the confusion ..next time I'll measure before I open my big mouth.

Like 406shark said, these were for a C4:
Corvette Parts   >   C4 84 Only   >   Suspension   >   Springs   >   10" Spring Bolts and Nuts Only

Like the pixs show (thanks 406shark for brining this to my attention) if I go with 10" bolts, It's gonna hang "below" the tire.
Alans setup


It looks like I'm gonna have to either go with a 17" wheel or 60 series tire to solve the problem. When I went from the 60 to 50 series, it was a 2" difference. Sheesh :-[ and I just bought these drag radials too.

I may try to find a 9" bolt and see if that helps first. I can probably find this size at a truck warehouse or bolt warehouse around here.

I've GOT to get it 2 " lower somehow.
:annouce:Any  :idea: on solving my problem guys?

Here's mine. The red arrow shows the bolt end's right AT the bottom rim.

If you need a nine inch (or eight and 1/2, etc) bolt, buy a ten inch bolt and cut it.  Nothing more than a hack saw and a good eye to do this.  It can help to put a nut on first, cut the bolt, and then back the nut off to help "clean" the threads.

Chuck

P.S.  I really like the raked look!   I'm not sure I'd fix that stance if it was my Vette.

Chuck... as usual, thanks for your great input. I think I'm gonna try your idea. I think I can safely go with 9".
I like the "raked" look too, but I DON'T like that 4.5" gap between the tire and fender lip. :nonod:
However, it should still have a raked look when done... :yesnod:

Hey Jack (or anyone), On the lower shock mounts (the L shaped ones: 1. Is there a difference between left and right?
                  2. What keeps them from turning downward after they have been on the car for a while? Are they splined or do they have some sort of key way?

I couldn't see any difference between the two Scott.
because it is also holding the strut rods, it can't turn downward.
On the strut side, there is a cotter pin throught the bolt.

They are splined & pressed in tight & usually you will need a special tool to get them out. I know van steel has the tool..it's to keep from damaging the threads.

I was lucky getting mine out then. I was worried about damaging the threads as it IS a tight fit.

Okay, I went down to my favorite tire shop where I bought my tires and had work done there in the past and the owner told me that it is the opposite of what you guys are thinking. He says:
That the bolt is NOT going to go down. It will go UP at the top instead because of relaxing the spring.
So it will go up at the YELLOW arrows and stay the same at the RED arrows.

If that is the case, this is good news as a 10" bolt will give me back the 2" I need.
BUT, looking at the pix above, I can't see how that can be? ???

UPDATE
I went to two large Fasteners & Bolt warehouses today and they did NOT have any. Special order and only by bulk. :(
It seems I can't find any around here.
I'm thinking of selling these tires, (they're brand new) and getting the 60 series size which would give me the 2" I need.

Jack,

The owner of the tire shop is wrong. Your best bet is to go with the C4 10" bolts. Then install the nuts and tighten them to the ride height you desire. Then cut off the remaining bolt. Then you will be left with the trade-off of looks to safety, or buy tires with either a larger sidewall or a larger diameter wheel & tire package.

Good luck,
Jeff  :burnout:

I was afraid of that. Safety has to come first. Besides having a bolt hanging down that low wouldn't look good from behind anyway.
It looks like I will have to go with a 60/275/15

Anybody want to buy this tire? I only drove one month on it last summer, about 100 miles.

I've got 2   10"X5/8" Bolts, but no nuts. Guess I could go down to lilly fastners & get nuts if you want them. I believe the origionals are 1/2" bolts , but I went to 5/8" for strenght...they went through the holes , but I purchased larger washers. 406 is correct in saying the tire guy is wrong. The top of the bolt is  connecteted to the trailing arm & goes down from there...a 9 or 10" bolt would give you a radius of 9 or 10",thus a 17 or 18" wheel is the only way to be safe. Give your spring a few weeks to settle in...you might just loose a 1" or so. I've got 3 3/8" clearance & flared fenders( add an inch without the flares) with 275/15/60 tires. You'll need clearance at the drags because your back is going to squat & you don't want a tire rubbing problem. I also like the raked look

I like the raked look too and would still have it with the taller tire. If I have to I can raise the rear a tad for racing.
Anyway, please send the bolts. I'm may try this, cut them to 9" and see if that helps first...

Which spring did you put on your car.  I put a 340# TRW spring on mine with the adjustable bolts that came with it and it does not sit anywhere near as high as yours.  I have my nuts set to just above the cotter pin on the bolt and it sits just a bit above stock if any.  It took about a week for my car to settle out but was only about 1/2" to 3/4" higher when I first installed it.  I think the settling was the bushings compressing over time.

You're up early...do you need the nuts too? I'll cut them if you want ...I've got an electric bandsaw that cuts like butter. Let me know

Sure Alan, cut them to 9" and the nuts too. Tell me how much and I'll send you the money. Your a life saver. I'll see how this looks unless someone makes me a good offer on my rear tires.

Yes, I have the 340#

I recalled reading on another forum a year or so ago about another guy who had my problem and it was the way he installed it... ie, how he tightened and torqued the setup BEFORE he let the car down I think. It was a long post like this one.

Just picked up the nuts & 4 washers. I'll cut the bolts tomorrow & ship everything. Send me $25.00 ...that should cover everything.

Today I put in the TRW spring. Unless your VERY strong, it helps to use a jack to hold the spring center in place to start the 4 bolts. There is a heatsheild and cover plate that is bolted with that.

I was reading a couple places that the four bolts used to mount the spring to the diffrential, that two are longer than the other?  ??? The article also said if you used the longer bolts in wrong hole you will crack the diffrential.  :o
I don't recall them being different sizes and didn't see that in the instructions either. Anyone know about this?

I am pretty sure they are all the same length.  I don't remember any differences when I finished mine last week.

Okay, some of you knew that I was told there was a clicking noise in the rear area and Brian and I discovered it was from the bolt rubbing on the spring:RED ARROW

It seems that the lip of the metal cup doesn reach up far enough:
(yellow arrow in pix above)

So I order this one with the larger lip. RED ARROW


But, once I got the nut off, I discovered that the metal cup was part of the spring :o This pix confirms it:


If you look at the rubber lip on what came with it, it is not very long: yellow arrow:


Even the old rubber had a longer lip:


So, what am I gonna do now. I think I'll start by sending this post to the TRW outfit I bought it from and see what they say?
