wheel judder acceleration from start

peelaaa · 9th May 2021, 16:27

Hi,

On hard acceleration from still in first gear, often there is quite a bit of harsh judder from the front end. As if the power can't be put down through the wheels.

Judder doesn't happen at other times.
Also seems to be a bit more vibration though the steering wheel than before, almost like a throbbing (not constant)

What do you think is causing that?

Lower engine mount most likely.

Although it was my first thought and recommend it is checked, when mine went it wrong was fine under hard acceleration from standing which is what the op says is happening. It only played up when moving off slowly.

Does it sound/feel as if the exhaust is thumping the body when you pull away? If it does then this too points to the lower engine mount.

Don't get a thumping noise but the suspension can feel harsh on rough roads, as if it's transmitting noise to the cabin. Shockers absorb well though.
I was thinking it could be the lower front wishbones or bushes maybe as I'm sure that's what starting wearing on a previous 75 I had.

Steering straight ahead, place foot on wheel and push see if there is any movement.
