Hi All Sifus,My E34 behaves strangely of late, I need master advice from all sifus pls.1. She makes "groook grook" sound when going over bumps and also on even light braking. The sound is also apparent when accelerate from standstill. Creepy !!!I have had the underarms and bushes all done oredi by Optimum Foo, but problem still there. Stabalizer Rod changed by another mechanic , also to no avail. I need a good and trust worthy one PLS 2. My steering wheel does not return to its original 12 oclock position after mild turn to 10 or 2 o clock ! It returns back only when its on full wheel to wheel turn. Strange !!!!I need advice and a trust worthy mechanic pls , Someone ?Tks in advance !
