nodwas Posted October 4, 2010 Share Posted October 4, 2010 Hi all, I have a V8 2004 with 125000 KM on it. (auto) I use it to commute and also offroad (dunes tracks) It has been well maintained however yesterday it started vibrateing badly when deccelerating and when accelerating and when cruising over 120 KPH. Also the revs drop very low when reverse is engaged and some strange clunking noise (not there before)(more prounounced in low ratio) One Tappet is definitly lifting as well. The fluids are all ok including the diffs. I also had the front prop shaft changed not long ago 100000 KM Any ieas what it could be? My ideas were gearbox/diff/rear prop shaft? but then im defintily not an indepth mechanic basic only. cheers eveyone! Quote Link to comment Share on other sites More sharing options...
landroversforever Posted October 4, 2010 Share Posted October 4, 2010 I'd try taking the rear prop off and seeing if the vibe is still there Quote Link to comment Share on other sites More sharing options...
sheltie50 Posted October 4, 2010 Share Posted October 4, 2010 Sounds like a prop shaft uj. Quote Link to comment Share on other sites More sharing options...
Pinn76 Posted October 4, 2010 Share Posted October 4, 2010 Totally agree, I fitted new prop doughnut 3 months ago to my disco due to bad vibrations at 55-60mph. Took a drive saturday and had the vibration back. Looked at the rear prop thinking it was the uj but was the doughnut again. Word of advise.........dont buy cheap one from flea-bay..........they dont last. Now going to replace rear prop and diff flange for the uj type.

If you replace the doughnut you also need to replace the support bush inside the end of the propshaft. The doughnut is not designed to support the weight of the prop or keep it centralised and if the support bush is worn the doughnut will last a matter of months.
