hey, not sure if ive got the right board for this but i have a question that id appreciate some help with. i have a 90 camaro rs with the stock 2.73 rear end with brake drums. my friend has a 3.42 posi disk brake rear that he wants to sell me but i dont know how to put it on my car. is this a hard thing to do?

 

What car is his rear end from?

 

It's very simple,if the other rear is from a 3rd gen.

 

yes the other rear is from a 3rd gen. its from a firebird gta i believe

 

It is a direct bolt in replacement, with the likely exception of brakes and emergency brake, which depends on some things like the year of the car the rear end came out of. These problems are likely easily solved. Scouring the archives here should lead to some answers which I don't have right now...

 

just research for speedo drive and driven gears online (also easy to do)
maybe a sticky here???
ill be doing the same any day now from 3.23 to 3.73

 

well the new end is coming out of a 91 forumla. is the e brake thing a easy thing fix after the switch. are there any walkthroughs here or anywhere else for the swap? what kind of problems will i run into while doing this swap and after the swap has been done?

You'll need to change the speedometer gears. IIRC, 17 tooth and 41 tooth.

I have a 1LE prop valve to install when I do my drum to disk swap, but I dunno if it is absolutely necessary. I have seen someone else do the swap without swapping the prop valve and get away with it.

And you'll need the parking brake cables.

Look around here, or even better, do a search. This has been covered a million times.

 

well i did a lot of research and such here on the site. ive gotten my new gears and im in the process of installing them. ive gotten everything out except the pinion. whats the best method to remove the pinion so i can put in the new one.

 

Are you replacing the gears by them selves or the whole rear end?

 

yea im just replacing the gears. any idea off hand wut size the bolt is that is holding on the driveshaft yolk?

 

I would have just change the whole housings off that car onto yours.

 

If you replace the entire rear diff you'd have an LSD and disc brakes.

 

ive gone ahead and changed the gears. went pretty well. definetly a better pickup and quicker acceleration. speedometer is off now and i hope to fix that soon as well. one lil issue, when i drive im hearing a small winning noise. my guess would be that i need a few more shims to one side or the other. anything else that could cause this. i dont wanna wear these gears out.
