rear, upper strut links
 

If you own a 124 body that is over ten years old your rear, upper strut links are shot. This is one of the five arms that make up the fantastic rear suspension in a 124. The top arm (strut link) bears the brunt of the force when cornering. Mercedes has developed an upgrade for this part as well as a new type bolt. The difference in the way the car handles after upgrading is very noticeable. P.
