hi, i renoisey bought an 1996 e36 318 se coupe from a private seller. The car makes a slow rattling noise (as in when you shake a small wooden box with a coin inside or something loose is hitting against something else). The noise only comes on when driving on bumpy roads and disappears when on motor ways and smooth roads. The steering wheel also pulls towards a side when going on a bump. Im pretty sure the noise is not coming from the engine. I have replaced the wishbourne (or something sounds similar to that) and allinged the wheels and trackers. However the noise and the steering pulling are still there and the mechanics i have seen, dont seem to know what they are doing. Cn you please help me.................
