This is my first post on this site. (I'm a newbie)  I just got my 78 Anniversary Edition Corvette and have been working through the issues.  Had to do all new brakes (including parking).  Finally got it out on the road without the fear of not being able to stop.  I have an issue that I suspect I know the answer to, but thought I would put out here to see if anybody had some thoughts.  Whenever I get on the gas the rear end feels like it is pulling towards the passenger side. It is very noticable. All of the bushings need to be replaced and that is next on my agenda.  I think that is the main culprit.  Has anybody ran into something similar?  Any help would be appreciated.

Welcome  to the forum Smiley  Bad strut bushings will cause this. You best fix is to go with adjustable struts.  The bushing in front of the rear axle usually wears too causing this problem also. Do you have a rear sway bar? If so check the busing on both sides. If you don't have one it's a great addition. It's probably better to go with poly bushings rather than rubber.

Hmmm. I had a bad strut bushing ( pass side ) and didn't recall it pulling to one side during accel but it's worth a shot. I bought polly bushings for like $20 and they were fairly simple to replace. hardest part was getting the old bushing out of the strut. I do know that even with new bushings I still had minimal adjustment left so the adjustables are the way to go if you can afford it. Are your rear tires tilted inwards on the top? that's a sure sign that the beshings are worn.

welcome aboard,

I would look also at your Trailing arm bussing's, when I pulled mine off they were totally shot.. I did not drive my 73 before starting a frame off restro but can only imagine how my side pull would have been.

Also welcome to the Group..

Thanks for all the replies.  I think my original assessment about the bushings is the best place to start.

When the bushings on the trailing arms fail, they allow the toe out to vary under acceleration and deceleration which effectively rear steers the car.  It is an uncomfortable feeling but needs to be fixed. 

Welcome to the forum and good luck.

My 75 did the same thing, I'd accellerate and the back would kick out to one side, hit the brakes and it would snap to the other side.  I jacked it up and found the fwd trailing arm bushings where gone, I could grab the rear tires "steer" them like the front tires steer.
Good Luck,
John
