    Hi Guys, I would greatly appreciate some advice on two topics. My 100 series cruiser randomly clunks when moving the gear sellector from Park to drive and also moving from drive to reverse when stationary of course. On the start of one trip this could happen and on the next slightly or even very little. Secondly when I drive and take my foot of the accelerator and then apply power again the car starts to vibrate randomly, if I then take my foot of the accelerator and apply power again there is no vibration. Has anybody experienced this and what is the econimcal remedy?

    Cheers NicSA

    I have twisted and yanked the driveshaft, there is no play on the u joints so not sure about the clunk coming from there. Could be dry though...will check thanks

    It really doesn’t take much to generate a vibration on the drive shafts. In an old Land Rover what felt like no play or a simple click when I twisted it was a significant vibration at 35mph.

    I have the same clunk when engaging drive/reverse nothing major so I would be interested in there is consensus on that. No vibration or clunk while driving.

    I would check:

    -cv axles to hub flange wear
    -front differential mount bushings
    -rear control arm bushings

    Any of those can simulate a clunk when changing gear directions. There is clearly play in the system somewhere there shouldn’t be.
