Differential bushing

V8Killer · 03-12-2012, 12:51 PM

Has anyone put on the 370z differential bushings yet? I have them but I wasn't going to install after reading this review.

I'll let you know. I have them up for sale but now I may use them depending on what Nissan tells me.

yeah unfortunately they can **** you with this "abuse" angle if they want. doesn't matter that its a sports car, they are meant to be driven hard according to nissan. who designs a subframe with a non-serviceable weakass diff bushing anyway?

All right I just got back from the dealership. They will be replacing the whole sub frame under warranty but there is a catch. If it breaks again they will probably not replace it and file it under abuse. If I decide to give them my aluminum bushings that I have they will install them but that will automatically void my warranty on that part as well as power trans. which I don't know why it would. I don't want to push the issue b/c they are doing under warranty and they do know all the parts I have. Has anybody installed these SPL aluminum bushings made for the 370z on our cars? I tempted to just say screw it b/c well they won't fix it if it breaks again anyway.

i wouldn't run a solid diff bushing in a street car, but thats just my opinion. They do seem to want to void your warranty if you run it though, I'd have them replace the sub frame. When it breaks again take it to a shop and have them install the whiteline bushing which will be out by then.

esfourteen. You wouldn't happen to know the pro's and con's of doing this mod with what I have do you?

I assume you have the solid mounts, they will transfer a lot more noise and vibration to the car and because of our hatch you will hear a lot of it. It will help reduce wheel hop, but the subframe itself is still mounted to your chassis with rubber bushings so I suspect it wont be entirely gone.

My last project car was a 97 240sx, I replaced the diff bushings and subframe bushings with nismo rubber bushings, they are basically this super hard rubber. It resulted in 0 wheel hop and virtually no additional noise. Since they aren't available for our car, I plan on doing the whiteline diff bushings and hopefully someone comes out with something for our subframe.

Thanks for the input, I will just go ahead and sell the ones I have. +1

tranceformer · 03-12-2012, 05:23 PM

I'd wait for the whiteline bushings. That's my 2 cents.

red6spd · 03-12-2012, 05:49 PM

In for updates. Knock on wood I dont have this problem but it might be a good idea to have the bushings ready just incase.

I'm going to try the Energy Suspension 350Z rear differential carrier bushings (part number 7.1119) at the end of the year. SPL told me in an e-mail the 370Zs rear subframe bushing is slightly smaller than the 350Zs "by a couple of thousandths". The two front mounts are the same diameter of course since they both have a R200 housing.

good find, I didn't even think to check ES. This should work as the polyurethane is somewhat pliable and the difference shouldn't be enough to interfere with installing it. The real problem is removing the factory bushing from the subframe, I've only done this once on a 240sx and it was a nightmare.

MaDMaXX · 03-13-2012, 12:51 PM

So, is there anything even close to the stock/rubber bushing that we can use? (personally talking about the 350z)

Mine has that streak down it since i bought it and i have experienced some really nasty wheel hop at times.

It's a DD so i don't want anything solid, but i'd like to think there would be something like the Nismo extra hard rubber bushing available for it?

Personally I would grab the set of energy suspension poly bushings, its really not harsh at all for a street car.
