Savage Vibration. Totaly Buggered ?

Ive got a bit of a savage rumble / vibration coming from the Landy. I know that it could probably be quite a few things, but........ It seems to appear when you get to about 20 - 30 MPH. Is more pronounced when under load. Goes away completely when you put your foot on the clutch. There is a distinct rumble, accompanied by quite savage vibration through the steering wheel and dash.

Gearbox related or engine related ??? Im lost as to where to start looking.

Any guidance much appreciated !!

Get under right away and check the prop shafts and the UJs.

Probably ready to drop off.

A big clue is this is LOAD SENSITIVE, and the engine is fine with no drive on.

Front propshaft is the first place I'd look. Friend had exactly this on a Defender recently. Both UJs were a mess, and then some of his mates realised they had the same problem. "Specialist" garage couldn't diagnose it!

I have just had a very similar problem and it came on very suddenly. It was indeed my front propshaft, or I should say the uj's at either end of it.
It was caused by a seized spline so I'm told that allows slight movement of the shaft forwards and backwards and because of this it had caused severe wear on the uj's.
As the guys have said before me I also think the front propshaft would be the best place to start.

Hi. Took the disco to the garage last night. On the way the front prop shaft parted company with the gearbox. I was stuck in a country lane, only wide enogh for one car. Took me an hour to unbolt the front of the propshaft to get moving again. The car would not move in either direction because the shaft kept catching on stuff as it rotated. Laid at the side of the road in a reasonable size stream, not my idea of an enjoyable evening.

Could have been worse uj failing have been known to lift wheels off the ground-not fun!

There was a (perhaps apocryphal) case in Leeds many years ago when the propshaft on a bus was said to have become disconnected, flailed its way through the floor and mangled several passengers beyond repair.

BUT, our diagnosis was right!

If he had done what we said he would have checked the propshaft BEFORE setting off.
He would have seen it was knackered big time, and he would have taken it off in the comfort of his own driveway / street. He would have tossed into the back.

Then he would have engaged centre diff-lock, and driven to the garage.

That's what he SHOULD have done.

Hindsight is wonderful!

If you managed to take it off in those conditions then its not worth getting the garage to fix it, you have already done half the job.

I know I could easily fit the new one. But, Ive no idea about ballancing it ? So I thought sod it ! Costing about £40 in Labour, Landy is shared so I only have to pay £20. Rather just pay that than bugger around with ballancing.

Im sure someone will tell me its easy to do. But I already had it in the garage booked in. Bit cheaky to ask for it back and do it myself now eh ?

Cheers for the advice anyway.

Pitty I though I could get away with leaving it. Should have just dismantled it on my drive as you say.

Are you kidding? Its a big lump of metal on a land rover, it doesn't need balancing. Anyone who told you it did was trying to win your custom.

If it was an F1 car maybe this would be needed but a prop on a Land Rover?

Get a new one and bang it on - all you need to do is make sure (if you pull the two parts apart) is that you line the UJ's up correctly so they self cancel any movment.
