Vibration

(1/6) > >>

Guy90:
Still trying to track down the vibration on the 90. It's worse at around 35mph but always there a bit whatever speed I'm doing.

Having a look underneath (and hearing some clonking on taking up drive, there appears to be some play in the either the front diff or the transfer box. I can turn the propshaft about an 1/8th of a turn with the transfer box clunking away. There is about 2mm of play on the flange of the transfer box.

Likely to be the cause? Is this amount of play too much?

Thanks,

littlepow:
Have you checked your UJ's?

ferret:
The play is normal. Check uj's first. and prop shaft slideing joints for play. If the vibration started after a lift or castor correction being carried out the only cure really is to fit a double cardan prop shaft with a discovery 2 output flange on the transfer box at the front.

Guy90:
Just fitted new UJs so they should be fine. The front prop is brand new (it was vibrating before that).

It has been lifted and castor corrected by the previous owner. Vibration has only started in the last couple of weeks.

I feels like it is the whole car vibrating though either transmission or though the wheels. It's always there but worse at 35mph ish.

Checked everything from bearings, wheel balancing to gearbox mounts but can't track it down :evil:

ChrisW:
Have you tried it without the props on? (One at a time obviously  :roll: )
