Wendell:

Check out a MB chassis manual for your car as there is an allowed height difference between the left and right sides. If my memory is any good, that maximum allowed difference is about 15 mm (or a little over half in).

It is like the allowed oil consumption rate. Some do not like any oil consumption so they fix it. Some live within the allowed amount for years. If you do not like the height difference even if it is within the specs, then have it equalized.

I just checked the chassis manual for W124. Here is the info.

Using a tape measure and measure from center of wheel to fender cutout. The maximum height difference between left and right, front or rear, should not exceed 15 mm.
