Its m3 evo 5 door, wen its under hard throttle it drives brill no problems, but wen the camber changes of the road or goes a little bumpy, it feels like the rear end is trying to steer! only at 90mph plus. It Only does this if say u go over a bit on a hill, mainly wen the road changes from being flat. Very hard to explain!!!

Our theory maybe that its somethin to do woth the diff witch is lsd, and i think its a plated one! Thinking that maybe wen the weight moves off one side of the car, its sendin more power to one wheel.

Its actuallly dangerous, u be driving hard to 100 go over a little hill or somthing and it will force to one side. Hope someone can help, The diif its noisy at all, and its fully 4 wheel alighined! camber and tracking all spot on. It gets very twitchy on uneven sufaces.

Thanks Matt.

 

i guess you have checked all the obvious things for something wrong not tight etc?

i have seen 3 m3's which have crack the metal bracket where the diff is mounted - but i doubt that would give you the problems your experiencing

Matt

 

thats brand new as ive split that b4. Yeah everything else okay.

 

btt

 

bearing?

 

wheel bearing? would i hear that tho?

 

i just had the same thing on the MR2 and it was sometihng not bolted up properly on the rear suspension/beam.

doesnt sound like the diff to me

 

true check bushes?

 

Rear arm bushes up near the rear inner sills, thats the usual fault, when split/worn they can cause a shit load of play at the rear wheels.

 

ofcourse yeah, the rear trailing arm bushes are VERY common to fail.

so are the rear topmounts
