[mudder110]

hi all just when I thought I had all my pre wet season maintenance sorted,
I now have a slight vibration not coming through the steering on acceleration. its not noticeable cruising wasn't there yesterday
checked drive shafts,viscous,wheel nuts, was in fourth at the time accelerating to just over 80ks stoped when I backed of has 335000ks on the clock I think its coming from the front any input appreciated
cheers

Interesting...I have a vibe at about 70-75 k's under acceleration. I'll watch the suggestions with interest ;)
Cheers

Sticking slip joint in the front prop perhaps?

What model is it?

Is the vibration harsh ie Engine rev speed vibration, or a slower drumming vibration?

I had an annoying vibration on my MY13 defender - only occurred on hard acceleration - caused by intercooler hose touching steering shaft, well at least until the hose burst.

I had a harsh vibration on my TD5, turned out to be collapsed engine mounts. I also had a harsh vibraiton on a V8 Range Rover - torn transmission mounts. Just need a little contact between any drive train component and the body or chassis.

Also might be worth checking the exhaust hangers are still there and the exhaust is not touching ... - Yep my TD5 did that tick a few times.

One trick to finding the cause:
1 - Park on a steepish hill facing up.
2 - Put your brakes on and note the vibration
3 - Put your handbrake on and allow the vehicle to roll back and be stopped by the handbrake, not the level of vibration
4 - Now repeat facing down.

If the level of vibration increases when you use the handbrake - then something is amiss with the engine mounts or transmission mounts. - A very slight increase is OK, but you will soon know if something is stuffed.
