Rear differential bushing failure

Big J · 02-01-2015, 11:02 PM

I am 99% sure it's not suspension related bc I have looked it over way to many times. Chexk out this thread I just made in the repair section.

rear end clunk noise

nismolucino · 02-02-2015, 03:12 AM

Its probably the clunk that comes from the rear axle splines, remove the rear axles from the hubs, clean the splines and put some grease on the splines and re torque the axle nut back on. As per nissan the axle nuts are one time use but I reused mine just fyi if you wanted to get new ones.

I replaced the bushing and mine was in fact bad. But what was causing the clunk noise was actually the axle nuts on the driver side wheel being loose. I appreciate everyone's help.

Awesome glad you found it,the same exact thing happened to me. I installed the diff bushing and still had that clunk and then I found the axles to be the cause.

Well... This sucks! Only 35k on my 2015 and discovered the bushing is leaking. Time to order a replacement and spend a Saturday underneath the "Z"...

Z1 now has a bushing puller that actually works on the Z34. If you're willing to pay for it or can borrow one, it makes quick work removing the OEM bushing. Otherwise, plenty of people have cut out the busted bushing with a saw-z-all.

I ordered that too...

I don't plan on taking a drill and sawzall to my subframe..

Once done with it I will sell for a discount to another person in need...

I don't track my car and have only done a handful of semi-hard launches, so this is rather disappointing. On the other hand I don't mind an excuse to spend the day working on the car...

FWIW, if you cut out the bushing, you shouldn't touch the subframe. You cut/drill out the center of the bushing then cut the outside shell of the bushing from the inside.

The dealer doesn't muck around with the bushing at all. They just order an entire new subframe with the bushing already pressed in

Yep... If I have to use a saw, which I don't plan on it, I will take my time to avoid cutting or etching the subframe. I guess the trick is to cut through most of it and then begin to pry it away.

Thanks!

The Z1 bushing removal tool doesn't make it easier. I purchased it and used it but would have been easier to cut it out. It took my son and I one pulling and the other using their foot for enough force to push it out using Z1's puller. You can't use an impact on it either causes too much heat.

Interesting. I'll report back on my results. I've got a breaker bar and some tubing for leverage if needed, although the space to work will be limited. I also have a sawzall if needed.

Today I experienced this myself. Plenty of curse words along the way

Would it be a good idea to hit it will some penetrating oil?

A good idea would be to cancel your Z1 bushing puller and to rent/buy a saw and get a blade that cuts through metal. You will save so much time. The puller is bs.

Hmm... I have a saw and blades for metal cutting. If the tool fails to do the job I'll contact Z1 about it...
