I've read various references to the importance of "center locking the steering" before doing an alignment on a Mercedes. I have an '86 190E 2.3-16v and would appreciate an explanation of what the correct procedure is to insure a correct aligment.

The steering box has a center position that can be seen by removing a plug. A pin is screwed into the hole which engages a dimple in the recip ball assembly.

The steering center also can be checked by removing the key and turning the wheel till it locks. If it locks with the steering wheel in the proper horizontal position then steering wheel is assembled to the shaft appropriately. If the box has never been off then this will place the steering in the center for most purposes. From this centered position the wheels are brought to the proper toe by adjusting the tie rods.
