I’m chasing a vibration in my 1982 300CD.
It comes on at around 40 mph. No real vibration in the steering wheel, though one front tire roadforce balances at 34 lbs (high).
I feel it primarily in the floorboard. With the car up (wheels on the drive on kwik lift), parking brake on, transmission in neutral, I can turn the driveshaft slightly. Maybe 1cm of play.
Center support bearing seems fine, flex discs, etc all seem ok.
Id like to lift the rear end, and make the car “drive”, wheels off the ground. Since it is an IRS, doing so with the wheels hanging will put a lot of force on the axles.
Is there a way to do this? Ferris Beuler style, up in the air, up on stands, run the vehicle. Don’t want to damage my axles.
Thanks!
