Vibration 2008 Defender 130

[lrbob]

Hi, My 2008 130 has driveline vibration over 90Km/hr, severe under load disappearing upon coasting. Disappears when rear prop shaft removed and travel on front only. Gearbox and transfer case eliminated as causes as has rear diff. New rear prop shaft fitted. This has occurred from new and I know of 2 other cases in new vehicles and 1 from another owner. However have spoken to some owners who do not have the problem. Please, can anyone help?

It could be out of ballance,can you see if any of the weights on the prop have come off.

There was an issue with handbrakes being out of round. Warranty replacement. Try searching on that, as I can't remember the details.

Thanks for reply. Weights have been checked. Perhaps I should look for a driveline expert.

Thanks David. Vehicle has been tested with handbrake drum removed. Vibes still there.

Hmmm - that doesn't leave a lot left to check does it?

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?

Interesting ... because mine does the same thing. 95-105km/h under load, there's some light vibration and groaning noise coming from somewhere in the drive train. I have written an earlier post about this back in October, but I haven't updated it because I have yet to receive a proper explanation from dealer/LR.

An inital workshop diagnosis (interstate, since I was on holidays) suggested there may be something wrong with the 5th/6th synchro hubs (because apparently that was a known issue). My home dealer then had it for a day and could not find anything that would point to transmission problems (ie. no metal shavings in the gearbox oil etc). They initially tried to blame my setup (ie. relatiely heavy camper on the back), but I told them wrong answer and to look again. On the second day a rather switched-on mechanic found something that might be the cause. We had it up on a hoist and spun it up to 90-odd, and sure enough one of the wheels started to have a life of its own. Diagnosis: off-round wheel(s).

I'm still awaiting the outcome of a warranty claim, and as a matter of fact are getting somewhat impatient with the unresponsiveness of both my dealer and LR. They'll both be receiving nastygrams shortly...

Having said all that, I'm not entirely convinced for the same reason spudboy isn't, because it only appears to happen under load. Secondly, I had some vibrations come from my brand new 200Tdi 110 back when, and they also blamed off-round wheels for that at first. At the time I just learned to live with it. This time I won't, and I'll be starting to make some noise shortly... (Scouse, if you're reading this you're welcome to point that out to your service manager.)

Met a guy a few months ago that had a F250 travelling around australia, he had same problem and found the welding of the steel wheel was faulty and let air escape from the rim slowly, he thought it was a slow tyre leak at first.
Ford replaced the rims for him as was under warranty.

There are alignment markings on the sliding member of the rear propeller shaft on the 200 tdi. If fitted incorrectly it will cause this noise and vibration at certain speeds. This has happened to me before. There are none on the shorter front propeller shafts. It could be the same on the Puma as there are balancing weights on it. Will send a copy of the relevant workshop manual page if it will help

[spudboy]

SpudFan's got a good point.

Anyone know if the rear prop shafts on a Puma should be in-phase or out of phase? Some models require the UJs to be aligned, but some require them to be offset...... although I thought this was only on front prop-shafts.
