Salam,
I have been trying to diagnose a problem in my Mark 2 grande 2.0 (RWD). The car vibrates at low speeds and upon initial acceleration but goes away after crossing 40 km/hr.
have gotten the following things checked so far
1. Drive shaft and u joint (no bends,dents and still has weights attached)
2. The centre bearing is not torn or broken in any way but the mechanic claims that it has become soft
3. The engine and transmission mounts are fine not sure about the diff.
Pretty clueless at this stage as I haven’t faced this issue in any other car

P.s The car is a 2004 Gx-110 4 speed auto
