Hey All.
have very limited knowledge on this and can't find too much online.
I have a RS rear end on my Evo9.

Diff is now making a clunking noise so need to have it redone.
are the clutch packs and ring and pinion the same across the mechanical (non ayc) diffs ?

I need to buy the parts and have it shipped to South Africa, who would be the best for this ?

 

Sounds like the rear end bushings are done. I have the same problem with my car. Rear dif bushings should fix that. Not sure about the clutch packs and diffs

 

I just fitted new diff mounts, bushings and rear sway bar links. So pretty all new.

It's mainly clunking when backing up.

 

Yeah then idk I have never had that issue with my car. Sorry I can be more help.
