My eldo 97 shakes sometimes at a slow speed like 5 to 10 miles an hour. I can well see my staring wheel shaking and driver and front passenger notes that the car is shaking. It does not feel any shaking at faster speed. Also it does not shake all the time. The tires are real old but visibly look ok. I could not find any buldge.

When I pushed car one by one from the 4 sides of the car, there is some sound from the rear side (most probably from the rear passenger side some sound when the car side is pushed. Can you please help me diagnose the problem - Thanks
