MB Recommended Replacement Interval?
 

My 96 E320 (W210) is getting up there in mileage (176K) now.
Just wondering what MB recommends for replacement of the following suspension related items:

Springs - On original
Shocks - replaced at 100K
Bushings - Original

There isn't really a recommended replacement interval. It is more of a replace the parts as needed if/when they are worn.

Springs don't usually get replaced too often, unless you want a different spring for a lower or firmer ride.

76k miles usually isn't too long on a pair of shocks unless they have been terribly beaten up on. If the suspension doesn't bounce, then they are good to go.

Replace when worn. The springs should be good almost forever. However over time the front ends tend to losen up a bit. It really depends on how picky you are and how much you want to spend. What some people consider normal wear and live with it, drives others nuts.
