Urgent question
I have a 1983 Camaro berlinetta. It is a 305/t5 combo. I blew the rear end the other night and took the pan off and the drive gear in the back of the housing had come apart. I got another rear from a 1988 firebird formula. The drive gear looks a lot bigger and everything fit together fine but when I put it together there was a little play in the gears and it locks up when moving. I don’t know if the pinion nut is not on tight enough or what. Please help!!

Re: Urgent question
I swapped all of the internals from the new rear. All of the original parts I pulled out. I left the firebird rear intact and just put all of those internals into my original housing. How do you set the load bearing and backlash?

Re: Urgent question
I figured it would be easier just to swap the internals. That is all I did. I took everything out of the firebird pumpkin and put it in mine and it is binding up.

I didn’t just slap mixed parts together. I figured it would be easier just to swap the internals. That is all I did. I took everything out of the firebird pumpkin and put it in mine and it is binding up.

the brakes were the same but the firebird rear also has a sway bar which mine doesn’t. I figured it would be easier just to swap the internals. That is all I did. I took everything out of the firebird pumpkin and put it in mine and it is binding up.

Re: Urgent question
Sounds like old bearings on old worn races.
even if you do setup close it’s short live.

Re: Urgent question
if you’re installing a new pinion crush sleeve my advice is to install a crush sleeve eliminator kit it uses shims and it’s completely reusable. This will save you a whole Lotta grief if you make any mistakes with a regular crush sleeve https://amzn.to/3JW8c0O
also using a Post and beam torque wrench is accurate enough for setting up your gear just check your lash before bolting everything back up
lots of YouTube videos on how to install them in the 7.5 rear end good luck

Re: Urgent question
So, blowing a ring and pinion is common in these cars. You should have swapped whole rear ends. But now you have pulled the ring and pinion out of the housing they were set up in and swapped them in to a different housing. The new to you gears should have been set up in the new housing properly. If they were set up properly they may have lasted a little while at best. Once ring and pinions wear in, resetting them up is hit or miss at best. At this point, buy a new ring and pinion/bearings and setup kit and have someone who does it frequently set it up.
