Having suffered the usual air suspension problems on a '94 4.6 HSE, paid a fortune etc. I have a new issue. When driving in a straight line all is fine, when turning even a gentle corner, in either direction, there comes a grumble from down under. Sounds like shocks/ suspension. The problem is I live in Germany and my Technical German is non existent. Before I register for a new mortgage and book a garage appointment, any ideas?
