Hey guys, so i've been trying to swap my diff in my s5 gxl, and i've heard it's easier to just drop the rear subframe. i've been searching but can't find any threads. i know i've seen some out there on how to do it, just can't seem to locate them anymore.

can somebody please help me out?? i really want to drive my 7 again =(

Thanks guys!

Just lower the sub frame enough to slide the diff out. No need to remove the sub frame.

well ya, but i needed to like know what bolts. aanndd i'm stuck again! the two studs that are on the diff that you need to lower the subframe to get to, how do i get those out??? i un bolted them but the studs are still there, that's the only thing holding it up..

The studs are welded to the car.

Use a pry bar or something. Once you take the nuts off the studs the diff should come down, if not you need to pry it off.

The two studs you're talking about on the diff are what mounts the diff mount to the subframe. There is a small plate under the nuts you took off and once removed the diff can slide upwards out of the two slots.

ok ok ok, so! i got the old s5 lsd out. and please no bashing cuz i know a bunch of you guys hate the welded scene, but i'm trying to put an s4 na (welded) diff in now. and the mounts don't seem to line up. they're really close, but no luck, any suggestions?

The mounts are the same, try again.

alrighty, just wanted to make sure my streak of bad luck with... well everything, was continuing. haha. thank you.

S4 or S5 the mounts will be the same.

Welded diffs are awesome. I used to race with a guy who has a SR20DET 240sx with a welded diff. That car could grip, drift, whatever you want and he daily drove with no problems.

Are you installing solid diff and subframe mounts? If not you will break the diff mounting tab off the subframe at some point.

I don't know about grip... My friend with a welded diff just went straight while trying to hit a corner. Understeer's a bitch when your rear tires just want to push you in a straight line.

That sounds like a mismatched tire problem or driver error, I'd driven plenty of welded rear cars and they were all fine.

i'm not installing any new mounts, but i am replacing my brake pads that had no meat on them anymore... lol fail

Yeah, I'd def get some delrin mounts + a mazda competition front diff mount. Pulling the subframe multiple times sucks ***. Ask me how I know this.


I found that when pulling the whole subframe out, you need to put it back up evenly. You can't bold the rear of the diff in then put the subframe in. It won't line up no matter what you do. Get a few jacks + a buddy if you can. That will make life super easy.

OH! Don't forget a pinion snubber if you're making some more HP than stock.

dm6_freak@yahoo.com

just a stock n/a s 5 here =) will it be ok if i don't run new mounts?

should be cool, while your at it hit up pep boys and get a suspension bump stop *aka pinion snubber what some people call it * and put it above where the diff will go , requiring you to drill a hole but thats it.

dm6_freak@yahoo.com

thanks guys, still having trouble mounting it up, but then again, i'm trying to do it by myself. a few friends are coming over later today, i'll let you guys know how it goes

again thanks for all the help!

a shop jack works great on this i did mine by myself, just drop teh whole subframe if you havent, its easier then trying to squeeze the diff up in there. then use the shop jack to lift it all up in .
