What about the obvious one of wheel balance? Although, if it only occurs under load and disappears when coasting, that does not seem likely.

If you get desperate you might try changing all the wheels with those from another LR and see if that is any different. Tyres could be out of round. What size are the tyres? Standard?

Is it lifted?

Thanks. Swapped wheels and tyres with another vehicle with no vibration and vibes still there. No not lifted.

Thanks SLT. Gearbox and transfer case were swapped out with a new vehicle with no result. Wheels & tryes swapped with a good vehicle with no result. Dealer tried hard without success. Land Rover now say it must be caused by the towbar, sidesteps,snorkel, driving lights etc fitted even though the problem was there from new before any accessories fitted. Dealer found the same fault in 2 new vehicles and another owner and assume all 130's have the problem. Anyone with a puma 110 have this fault? If not could it be tailshaft angles which would be different in a 130? Problem is much worse when engine loaded e.g. towing or carrying a heavy load.

what about bearings in diff head and/or rear diff hubs?not good quality or not lubricated? greased? wheel nuts not tight enough?
spose you checked them already

Have a check of the rear sway bar, see if it at times it is touching on the tank guard. I had a Perth dealer spend 3 days trying to find a similar vibration on my vehicle with no luck. I only found it when I noticed rust on the bar where it had been touching the tank. All this assuming that your 130 has a rear sway bar. Hope this helps.

I have a similar vibration in my 2004 Td5 130. Would be interested to know about the need for offsets in this model too. Also could non standard nuts/bolts at either end of the prop shaft be an issue

wheel nuts i mean the big locking nuts holding the bearings in place, if it is loose your wheel will wobble and vibrate.

Do you mean the hub nut???

Thanks to all for interest. Wheels and tyres have been swapped with another vehicle with no result. Rear prop shaft should be out of phase which suggests an alignment problem. Land Rover are of no help saying that the problem must be due to accessories fitted [towbar, bullbar, snorkel etc] even though the vibratii e expert to measure propshaft angles to see if the problem is there. It seems logical as removal of the rear propshaft with vehicle driven on the front only removes the vibratioin. It appears Land Rover has a problem with 130's in this regard and wno't or can't fix it.

Didn't read all the posts but the output shaft on the transfer? Mine did that with the same symptoms.

Could be t/case output shaft as Edd suggested.

Vibration problems also occur if the bolts in the flanges for the uni-joints are not tightened enough (because of the small flange used, it is difficult to get them tight with ordinary spanners).

The 130 has a longer tail shaft. This reduces the angles at the uni-joints, so it is not a problem with uni-joint angles.

The natural frequency of longer tail shafts changes with length (everything else the same), so this could be a reason. Also longer tail shafts will suffer more than short shafts, if they are running out of true or with slight runout of the t/case output shaft.

As length is increased it becomes necessary to use a larger diameter or heavier tube in the tailshaft construction to avoid problems associated with a longer tail shaft.

I haven't had much to do with 130's, but it is typical of Land Rover not to have robust drive trains. The uni-joint yokes on earlier rangies are marginal for their operating angles and they made these worse in later vehicles (as Land Rover tend to do).

My best guess is the 130 tail shafts are poorly designed and manufactured - they are marginal to bad in some other Land Rovers.
