The Definitive AU Diff Topic

[Ben]

Looking at putting 3.9s into my manual 01 xr8.

Obviously not something that I will do myself. Will go to a specialized shop on the GC looking at Nerang Diffs. But curious what causes some Diffs to become noisy after changing gearing.

Unsure where I will get the gears from but am hoping Mal Wood still offers something that would suit.

Besides finding the correct speedo gear what else will I need to have the job done or anything else that should be sorted while its opened up.

Cheers.
