122s vibration under acceleration

Higgy240 · Jan 24th, 2024, 07:38

Hi, I've just discovered a bad vibration when accelerating in the low rpm, getting worse every time I drive it, happens in all gears and disappears once cruising, I'm guessing prop shaft, going to get underneath later today but if anyone has any pointers it's always nice to hear.
I changed all engine and gearbox mounts a couple of months ago along with new wheels and tyres.
Cheers

Likely the centre bearing rubber mounting has split but it could be the rear U/J. If you take the whole prop shaft off, mark the two sections so they go back in the same positions.
