Mercedes-Benz W202 rear tyre wear and rear alignment angles
220DC280C200 CDI
Why do the W202 rear tyres wear on the inner edge even though the angles have been adjusted?
The causes can be worn outer joints of the lower control arm, the adjusting rods or the front rubbers of the rear subframe. They are replaced when there is play, and the angles are adjusted again. It is worth replacing the rear bushings of the rear subframe at the same time.
What are the reference values for the W202 rear alignment angles?
According to Autodata, the rear toe is 3.66 mm, tolerance +/- 0.78 mm. The value in the repair manual is 33 minutes +-7. Rear wheel toe is generally about 3-4 mm.
How is the rear wheel toe adjusted when a part of the track rod has been replaced?
Adjust only the side of the rod where the part was replaced and leave the other side alone. First check the condition of the lower control arms and joints, because loose parts and wrong angles wear the tyres. Steering and suspension parts are safety-critical, so have a workshop inspect them.
