On the weekend I had a look at the strut mounts in both my 190E and 300TE. As I mentioned previously, the passenger side mount on the 190E is cracked. The crack appears to be right through for half the mount and does open and close slightly when pushing down on the front of the car. Guess I had better replace that one. The other mount on the 190E and both on the 300TE look fine. They do still show some movement though, probably only about 1mm when firmly "bouncing" the front suspension.
For some time now on the 300TE I have also noticed a slight knock in the front struts when cold. I have been told that this is common when they get a bit of age on them. It goes away when they warm up and does not seem to affect their damping.
For reference, the 190E is a 7/90 build and has covered 212,000km and the 300TE an 8/90 build with 173,000km.
