Figured I'd post pics while I'm doing the bushings.

My rear diff bushing took a crap on me a couple years back. I was just out of warranty and dealer wanted insane $$ to replace the whole frickin rear subframe. i said fvck it and left it the way it is. Fast forward a few months back and a member on MyG37 figured out that the Whiteline Z33/V35 diff bushings are a direct fit. So I placed an order for some Whiteline bushings and a Nismo finned diff cover a couple weeks back and now it's time to get it done.

Exhaust, sway bar, driveshaft shields are out.
Driveshaft center support bearing dropped and driveshaft disconnected.




Axles disconnected and supported with zipties.




Diff dropped from the car and front bushings hammered out.




Heres the GCC spec finned diff case if anyone's interested. No I don't have a part number.




Whiteline front diff bushings installed, old diff oil drained, new Nismo cover installed and fresh fluid has been filled.




Tomorrow I'll be cutting out the rear diff bushing with a Sawzall and replacing it with a Whiteline bushing before popping everything back in place. Fun times ahead.

 

Well I'm done with the install.

Here's a couple more pics I took along the way>

Factory bushing after cutting with a sawzall



Drawing the Whiteline bushing from the rear



I'll take more pics tomorrow in the morning.

 

I'm prolly gonna need to do this soon. Subbed.

 

Drove the car up and down the street today. No noticeable noise or anything. Rear end felt much more solid. I didn't accelerate hard but I can tell the transmission of power is MUCH better and more direct.

Here's a final pic with the Nismo cover installed

 

what may I ask are symptoms of needing to replace the bushing, or what all were you feeling on the car?

 

In the front end, it was a metal to metal knocking sound in the lower control arms.

 

as this generation gets older, documenting findings like this will be important to keep the maintenance of these cars. thank you!

 

2ndgen, before I did this I didn't notice much except a very faint loose feeling in the rear. The best way to describe it is kinda like worn drive train parts where there was just a bit too much slack. I only realized this after replacing the bushings to the Whiteline ones and noticed the lack of diff movement and the more direct power transfer afterwards. Just to emphasize, it's been a couple years since the diff bushing went out and it took a while for all the fluid to leak/dry up so I kinda got used to the loose feeling over time. It wasn't a sudden change kinda thing. I'm sure if I left the old bushing it would've worn out more allowing even more diff movement and clunky feel so it's good to replace it once you notice any fluid leaks from the bushing.

lippstuh, you're welcome!

 

Thx for sharing ..
is it true that whiteline bushings install are a bit harder than SPL's ?!

 

Im not sure but I think the SPL solid bushings will require the removal of the subframe and a press to push in the bushing. You dont need a press to install the Whitelines. Cutting and removing the original bushing was the hardest part.

 

^ i see .. Thx buddy.

 

I was told by infiniti dealer my rear subframe was leaking during normal 27 point inspection at oil change intervals. Guys of course were very vague as to which part needed replacing. Been doing some research in forums as to which part i may need to replace. I notice my car kind of takes a while to take off when changing gears. Feels like its dragging or something. This is really annoying. Anyway, i changed my rear brake pads today... Car is very low so when i lifted the car i took the time to look under it. What i have been seeing in the forums i saw today in my car. Saw the hydraulic fluid on my differential. My bushing needs replacing. I saved a lot of money by doing my own brakes and changing my drive belt. Would like to change the bushing myself only it looks like i would need that differential bushing removal kit. Anyone one know where i can get one that i will be able to purchase myself?

 

Buy it here.

Set aside a whole weekend for cursing. Removal of the rear bushing is not easy.

 

Doing mine this week, such a pita getting the rear bushing out. The sedan has hardly any room to work. Giving up for the night and hitting it again tomorrow.

 

Successfully installed. If I had to do it again I would highly recommend a reciprocating saw that pivots 90 degrees. Normal ones like a sawzill are really hard to work with because of space constraints, but I managed to get the job done.
