Vibration and shudder coming from rear only in 5th gear
starts and seems worse at about 2800-3000rpm (110-120kmh)
Most noticable on moderate throttle, just before boost comes on, its hard to tell if its there when boost comes on since the engine gets a bit noisier but on hard acceleration it smoothens out..
Same speed or same RPM in 4th gear is fine, smooth as.... only 5th gear
any help would be much appreciated..!!
FYI- i have brand new tyres put on 2 weeks ago, Done a wheel alighnment with rear camber adjusted and front toe adjusted, also done wheel balancing twice on all four wheels as the first time they didnt do it properly..
the second wheel balance the guy said 3 of my wheels (Front left, and 2 rears) are buckled..not sure if this could be the cause of vibration but i do know that this is why my steering wheel vibrates..
Wheels are 18 x10.5 all round with them wrapped in 265 35's..
Thanks in advance..
