Steering question
 

This is for my 1987 300D.
My steering wheel is not centered, it's turned to the right at about 1pm while driving straight. Car sometimes pulls to the right but after a left angle turn on the freeway it stays straight (steering wheel still to the right). Any ideas on what I should replace?
No other noise or suspension loosness that I can notice.
I am whipping this shing back into shape little by little..:D

Check the idler arm (right tie-rod hooks to it) for play, tie-rod ends and ball-joints, upper strut mount rubber, and the control-arm bushings. Could be any of them.

I had a similar problem on my '87 after an alignment, the shop forgot to tighten one of the eccentrics/bolts on a lower control arm and it was shifting.

You can also do a crude alignment check by looking for sawtooth wear across the front tires, ... line one front tire up so that sighting across it it lines up perfectly with the rear tire outside surface and see if the one on the other side is close (should be barely outside of lining up with the rear on the other side). This will tell you if it's way off, which it sounds like it might be. Also, if the car is sitting high in the front when you park or the outside tire edges are wearing, it is excessively toed-in, / if low in the front when parking (or high when backing up) or wear on the inside edge of both front tires, it is severly toed-out.

The factory alignment procedure requires a pin to lock the steering box in the straight ahead position as a reference. The steering wheel should be in the natural position when the pin is in place. If not, remove the steering wheel and set in the correct position.
