Hello,
Car: 84 California 300SD
Wondering if anyone knows what is causing my vibration problem. At approx 60-80 mph when i let go of the accelerator pedal suddenly, I get this hummig noise coming from underneath the car..from the chasis...feels like something in the driveline is rubbing. It goes away, if the accelerator is depressed again.
I checked the condition of the transmission mount, that looks okay and none of the exhaust hangers are loose.
Only recent driveline work was a new differential installed about 6-8 months ago.
Any ideas on what to check?
Thanks
