vibration problem

[Caterman]

just found spring issue 5 2006 of LRO page 210, what is purpose of heavy metal cylindrical item close to font diff.  reply is  it is a harmonic damper to reduce vibration on front axle. :!:  any use to you, i have one on my disco.

RRC didn't have them untill the (metric) EFi modles with thicker props.  I've binned mine and it doens't make that much difference, it's not the cause here I feel.

I'm going to suggest you try driving with the front prop removed (and difflock of course) to see if it goes away, then try refitting that and removing the rear.

hi mate.well ive done as you said..... no difference at all im afraid. still got the vibration coming up through the steering and the whole truck...

i have just been under the disco again and used a pry bar in the bushes on the panard rod. they dont feel too bad to be honest....about eaqual both sides. maybe a little soft. i might put another steering damper on her anyway just to be sure. the front steering bar seems alittle graity.... ie the ball joints seem seem like they bind slightly but still move. the rear tie rod bar seems ok and nice and smooth. im slowly loosing the will to live with this.......no idea where to go next  :(  :(  :(

Might be!!!

my vibration on over-run was due to the transfer box having too much play in it ...fitted another gear box and transfer box complete and airing on the side of caution fitted a new clutch at the same time ,and then found out the new clutch was faulty so had to replace it again a week later   :(  :(  not happy with ap clutches at the moment

Ok, I'm going to have a long think about this, I need to recap.  Someone buy me a drink......

just a quick point ap clutches have admitted a manufacturing fault on the release bearing and are going to reimburse me out of pocket expenses  :D  :D

Ok, so let's recap, you know it is NONE of the following

Propshafts
wheel bearings
wheel balance
external play in the axles ie driveshafts/pinion bearings

did we say the gear you are in makes no diference?

Have you checked the drive mambers and bearings in the outer ends of the front axle?

If so then one more thing is to try disconnecting the propshaft and half shafts from one axle, then the other.  Yes I know it's work but......

Also did we discount any sort of misfire in the engine? in 5th ours runs approx the same engine revs as prop revs, so 2 tiny vibrations combine to get annoying.

Did you try a different set of tyres? not just swapping front to back.

Oh, check the engine mounts.
