vibration

[chizy]

Getting a vibration at about 30 mph which then disappears at 35 mph.Not there all the time only when accelerating,keeping to speed limit etc, goes when off the throttle.
Don't half make the top tailgate rattle when keeping to speed limit in town!!!
Suggestions??
300 Tdi with R380 by the way.

Thanks in advance

Could be a prop shaft uj or balance problem had a similar problem rr mine was a uj

Sounds like your front prop uj's.
Could be wheel alignment/balance...have you 'curbed' it recently?

Nowt to say it's not the back prop either.

Let's see, does it vibrate a little at around 60 too?

Cheers for the responses.
It hasn't been curbed (unless SWMBO is keeping quiet) and only vibrates between 30 and 35. Nice and smooth below 30 and smooth after 35.

Steering damper coming to the end of it's life?

My Disco had the same problem around 40mph, changed the damper for an old man emu and it's now fine.

Thew bit about throttle is significant.  I had a rear diff collapse and the early stages it was a bit like this :shock:

A UJ might be there all the time, might not but I don't think it would only disapear on overrun.

One nasty thought is something engine related, try it in deifferent gears to try and eliminate which side of the cogs it's occuring.

 I was getting a vibration at back about 3 weeks ago,4 days later a big clunk from the back and loss of drive.I took rear diff out and found the 4 planetry gears sat in the bottom of the axle casing  :shock:
Obviously a used diff was fitted,but what can cause this to happen ?
My front diff has been whining for ages but the back one was quiet until it just went bang ! It was full of oil also so not ran dry.

Cheers for the suggestions fellas.
I am going to start with the basics.Going to drop the front prop and see what happens.If still there, try the rear etc
If it still does it, then what with the ABS still giving me s**t, anyone want a burnt out soft dash 300 Tdi????? :shock:
Still, gotta keep smilin'- it would be boring otherwise

I think bad luck really, usually a used diff is a known quantity, proved out if you like but you may have got one that had a nasty shock and weakend something, or it may have been weak since it was made.  One part failing will quickly take the others with it.  Unless there was a significant event shortly before it failed I'd say there wasn't much you could do to predict it.
