I have a 440GL 1700cc 1990 78K
When I drive the car,if I take my hands off the steering wheel the car vears to the left.
When I go over potholes there is a clonking noise from the front of the car.
I've had the car in the garage and the tracking,tyre pressure and brakes are all ok.
They say they can't find anything and all they can do is replace parts
until they get it right. Can anyone help i.e. which parts?

Thanks Paul
