94 E320 Wagon thumping rear suspension
I just finished some extensive work on this car:
Rust repair
New windshield
Head Gasket
Engine harness
O2 sensor
Cat back exhaust system
Throttle actuator rebuilt
New rear hydraulic accumulators and associated plumbing due to corrosion
New blower motor
New alternator
Rear calliper rebuild
Fuel pump
As well as other more routine items.
And, although I replaced the rear accumulators the thumping that I thought was accumulator related is still there. It is like every bump and ridge in the road is being transferred into the rear cargo area of the car. I have had the car on the hoist any number of times (a luxury I have in my garage) but cannot see any worn parts, nor can any of the various suspension elements be manually moved. That doesn’t surprise me though since a hanging suspension would likely be under some tension and arm strength may be unlikely to induce the problem. The handling seems OK, but since it is my wife’s car, it may be off slightly and I cannot tell.
Can someone direct me to a likely component to check?
Thanks,
John
