tried to get diff. square head plug out with 12 point socket no go. six point socket doesn't fit either. No room for an open end wrench. Suggestions on what to use to get this plug out? heard somewhere to use a 5/8" crowsfoot wrench?

Yes a 5/8" crows foot on a 3/8" extension, I also read that removing some of the spare tire brackets helps too Smiley I want to state that I read that somewhere so let me know if it works Smiley I'm sure someone will pipe in and let us know if we are going in the right direction Tongue

Mark is correct & you can also use a 8 PT 5/8  socket (they are at Sears) if the ends aren't rounded off. Sometimes taking the rt rear tire off & using an extension helps. Are you just changing the fluid?

yes . That fluid has been in there since new and it has been suggested I replace it. Any tips on sucking out the old and putting in the new? Its very tight quarters with limited space. I know the ideal is pulling the back cover off but i.m not up for dropping the rear to do it.

I just used a small suction hand pump & reversed it to pump the oil back in (mine screws on the the gear oil bottle) with the posi oil it takes around 3.5 qts. Then do your 6- or 8 figure 8's.

The crows foot did the trick. Now I just need to get a suction device. Does it take 3 1/2 quarts? I have seen fluid sold in the vette mags stating I need two 23 oz. and one 4 oz. posi additive.

Put the additive in first 4-8 oz then fill until  the oil comes out of the hole. How much it takes depends on how much you sucked out, but it will probably be 3-4 pints  ....Don't know why I was thinking qts
