I have a 1995 3.4 auto with 140k and it is starting to make a small grinding noise when i roll in [D] and I am thinking it is time to replace the 2 piece driveshaft and possibly the rear end

could I get some wisdom from people who have done this before? will those fancy aluminum ones fit on mine?

 

Yes you can use either an aluminum or steel 1-piece driveshaft from just about any 82-02 Fbody. The LS1 3" aluminum shaft is a popular upgrade, and can usually be found $100-$150 used.

Another nice upgrade for 93-97 V6 cars is to swap in a stock rear from a 6-speed V8. This will give you 3.42 gears, limited slip differential and disc brakes. A used rear in good condition can be had for around $250. Keep an eye out for one local so you don't have to pay shipping.

There a bunch of info about the swaps on my website.

 

if i upgrade to 4 wheel disc dont i have to upgrade the proportioning valve too?

 

I didn't, works fine for me. I also swapped in the 98+ front brakes too.

 

I also swaped my rear end from a t/a and the steel DS. Did it myself, and was easy just swap out. But your e-brake will never be the same. Dont know about the front mine is still stock.

 

Maybe you're UNlucky19, as long as you used the e-brake cables that came with the new rear you shouldn't have a problem. Mine work great, much better holding power than the old drum brakes.

 

its pretty easy straightforward. Little rough on the physical part but not outragous.(rear axle is heavy as hell)

brakes will be fine... just make sure you bleed the hell out of the lines.

 

yeah what he said. I had to replace my rear end shortly after i got my car back in high school. got a rear end from a 95 Z28 and went to town in my drive way w/ a few tools and no knowledge of what i was doing lol. but the rear end = heavy as a mo fo
