Differential bushing

BGTV8 · 10-07-2013, 04:22 PM

I had the Whiteline KDT911 kit fitted to my Z34 yesterday as the OEM PoS rear diff bush had burst and leaked silicone all over the diff cover.

It is like night and day - axle hop all but cured, and no noticeable increase in NVH.

Whiteline were dubious about NVH as the 370Z rear diff bush is slightly smaller diameter than the 350Z (which is the KDT911 part), but since they won't start research on the Z34 bush until Jan 14, I was not in a piosition to wait.

Getting the bush out requires making an extractor tool (which can be used to fit the new bush along with a healthy dollop of lube).

KDT911 was getting hard to find here in Oz, but found a kit at a local parts distrubtor in the end. Seems like lots of US parts distributors are out of stock as well.
