Irratic vibrations

[samiam4]

Guys,

My 86 300E is driving me crazy- The vibration can be almost none to mild and from 45mph to 70 mph. Sometimes none- Tires are new RE960's as the last set was suspect and old.

All suspension is fairly new. Would could and Idler arm start to give such symptoms? Almost like a loose wheel which somehow center's itself while driving. Going to check wheel brg play today.
