    Have you tried changing sponge backing pad?
    Is the bearing hot?

    If not that difficult to replace, you just need the right tools. There is one dodgy washer. It's like a pinch washer (sorry don't know correct name) with 2 eyes. You need a pair of plyers with 2 small teeth at the end to fit in the holes. sorry don't know the correct name for them either. Somebody help me out here, not doing a very good job of explaining.

    defiantly worth checking the sponge backing pad, amazing how they make the head wobble when they start to perish or split.

    failing that yes fair chance it's the bearing fairly easy fix but you will need a few tools (circlip pliers) punch set and a hammer etc maybe some release agent to get old bearing out - try not to split the bearing as they have a tendency to leave the outer casing ring behind when the split - if you need some advice feel free to give my engineer a call

    the bearing you can get from here: http://www.belmoretools.co.uk/acatal...l_Bearing.html

    just like to add we now sell the correct driveshaft grease in ready made syringes - something flex should have sorted years ago after someone there had a brainwave to discontinue the driveshaft grease see here: http://www.belmoretools.co.uk/acatal...ft_Grease.html

    Have you checked the driveshaft?
    Thats usually the first sign that its about to go.
    If the screw in the middle is hot then your bearing has gone and should be replaced. (we tried to clean the bearing and wd40, it went for a while then snapped driveshaft= new driveshaft and casing 70)

    You cant get into it from the driveshaft side, you have to get the solid plate where the pad sits on to come off, and that is a task in itself. I can't remember if it comes off clockwise or anti-clockwise but it does unscrew then another circlip is there to take off and then it comes away.

    Thanks that what I thought, a little bit like you soaked it in wd40 to try and help with the unscrewing but that seemed to free up the bearings so kept on doing that but it was only temporary and eventually broke the driveshaft
