1995 WRX, has developed a rumbling from the rear which increases with speed and develops a vibration above 70-75 (obviously on private road at the time :P )
Doesn't seem to make a difference when going round left-hand bends or right-hand bends.

Could anyone shed any light on what the possible causes might be?
And is there a 'recommended' servicer to use in the Rugby area? (between Coventry and Northampton).
Any help appreciated.

 

wheel bearing? wheel balance? has it ever been rear ended or smacked into a kerb sideways etc?

 

Blitz exhaust

 

Heh, no. It is completely standard
Wheels recently had new rubber put on them, and were balanced, etc at the same time and, afaik, it's never been rear-ended or spun into a kerb.

Guess I'll have to get my credit card out and go find a garage.
