The main influence of driveshaft vibration is from the operating angle of the uni-joints (unavoidable). But the way other vibrations combine with those and build up when the shaft is rotating near its natural (resonance) frequency, complicates the affects and is why not all experiences are the same.
Even things like engine and gearbox mounts and their alignment can give different results for driveshaft vibration in otherwise identical vehicles.
Thanks John, I think you are right in that a complete new prop shaft is required. My vibration is very severe when loaded or towing. Cheers
Having just bought a 130 Td5 and having experienced the same noise between 90 and 100kmh it's got me thinking... I had a 101 that used to do the same thing. I cured this by making up a CV jointed prop but the angles were mad on 101's. Anyway, back to my thought... A prop (if both flanges are parallel) should be 'in phase' (joints alligned..). Defender 90's are out of phase as the front diff is tipped up.. Having just looked under mine, the diff flange (Salisbury) is at 90 deg to the floor, but the transfer box is tipped back slightly. Is it worth trying the prop 1 or 2 splines out of phase.....?
Thanks for interest. My 2008 130 came from LR with rear prop shaft out of phase which suggests that they knew of this vibration problem but sold them anyway.
Actually my 2008 130 came from LR with rear propshaft out of phase. Tried it in phase and vibes still there.
Potential resolution here
Have you had the clutch changed yet lrbob? My 110 had a bad vibration in 6th under load from 90 - 110 km/h. This dissappeared when the clutch was changed due to the anti-rattle springs coming loose.

Hi there
A friend of mine in Whyalla had a simular problem..........took us some time to find it.
We tried wheel balancing checked diffs and tail shafts but found the problem to be the tyres.
They dont like the SA Heat in the summer (very agressive tread pattern, but soft).
New tyres and it drived like a dream now...

Thanks Tim, Clutch was inspected when a new gearbox was swapped in and out in attempt to find problem.
Thanks Ellard. Dealer swapped all wheels/tyres with some of known quality without result. Cheers
