If anyone can unravel this one I would be grateful and impressed.

I have a fairly new (1000 miles) 05 Sti. After a good run, say 70 - 100 miles and most noticeably on A's and B's rather than Motorways a rattle starts from the rear. It's like loose top mounts although heavier. This is very noticeable at low speeds 15- 30 but the most disturbing part is the noise, from, I assume the rear diff, at parking/manouvering speed, like a graunchy, cracking noise and the car literally lurches sideways. This is with the diff in auto - I would expect noises with it locked. Everything has been checked for tightness.

Ideas on a postcard or A4 if necessary.

i have the same on my JDM v9 , i took it to TSL yesterday for it's 1000 mile service and Graham said it's nothing to worry about it's just the diff is wound up tighter on these models and the same thing happens on his uk car .

 

Thanks for the reply. I was told the same but couldn't believe it. Anyway I'm very happy with everything else- goes pretty well so who cares about making funny noises whilst hopping into parking spaces!
