My tach works when it wants to, but my speedometer doesnt work at all. How do i go about getting it to work again. Ive asked one of the trusted mb shops in the area and he said it might be the cable near the drivers side front wheel is torn. He asked if there was a spinning noise near the wheel when im driving (which there is) and that might be whats causing the problem

Can you guys help me please!

This is on my 83 300SD
