    Firstly, Hi... :)

    I'm hoping some of you could help or have seen something similar. I have just had the VCU support bearings replaced on my 2004 Freelander as the rubber had disintegrated, but now with everything back on, there is a vibration coming through when driving at 50mph+. Under 50mph = no vibration. Remove the VCU and prop = no vibration.

    I've had the prop and VCU sent away to a balancer and all is good but they did notice 'oily stuff' dripping from front cv boot when on the balancer. Apart form that, all seems perfect.

    Anyone seen something similar? Have any ideas?

    Many thanks in advance.

    Just had the same thing happen to mine but at a higher speed. Mine started vibrating at 65mph. Found the front part of the front prop that is sealed inside of the end of the prop that fits into the IRC had collapsed. You can buy a repair kit but this didn't work for me and I ended up buying a new front prop. £85 off ebay. Not genuine part but has done the job.
    Might not be same failt but sounds very similar.
    Regards
    Paul

    I've just done the same job replaced 2 x new vcu prop bearings and 3 x new UJ's. I used x aftermarket prop bearings from rimmerbros and got the 50 plus vibration.
    Took rear prop off same result. Took from prop off and checked it, all good. Dropped the vcu and placed it on a bench supported by 2 identical steel box section battens and rotated it. The result is it wobbles which I believe is the crappy aftermarket bearings from rimmerbros so now decided to get a pair of GKN ones. Has anyone had similar problems with these crap bearings.

    Avoid cheap for anything drive train related. The results are never good with cheap stuff. Cheap VCU bearings don't last long, so it's false economy to use them.

    Hey, vibrations can be caused for lots of reasons. I’ve had a few on both of my landys. Couple things to add to the “check list”

    1) wheel bearings
    2) imbalanced wheel/s.
    3) buckled wheel/s.

    Mine vibrated for a year only around 55mph, was fine at other speeds, I then got a puncture randomly, putting the spare on instantly cured the rumble. When new tyre was fitted to that wheel etc, the wheel nearly jumped off the wheel balancer it was that warped, but looks fine to the eye.

    Cheers
