    Changed the bearings
    Got the dampers back from AVO. Had the damper rods shortened by 1.5 inches.
    Added 2 more bump stops to each damper. They now have 3 bump stops each - shows how wrong the damper top mounts are in respect of wheel/body position.
    Put it all back together and lowered the rear of the car about an inch (was high before to avoid hitting body as I didnt have enough bump stops)
    Have about 2" suspension travel in compression and about 2" in extension
    Drive shafts at much better angle now.
    At full droop now have 1-2 mm of shaft plunge
    Car feels a lot better, and no noise.

    Thanks, Steve.

    I can see the drive shaft looks a lot happier, with less of an extreme angle, but blue rings (are they the bump stops, or would they be at top of travel...?) and the height of adjustment nut look the same as in first photo.

    Any change at top of damper, apart from shortened rod length?

    the blue springs are helpers, for when they go go full droop.
    The adjustment looks the same, but dont forget the dampers are effectively 40mm shorter.
    Please below post about springs/dampers. Neil is the real brain.

    Re: Corse I CV joints

    Well
    Went for a short drive with the new CVs fitted. Got 400yds and loud bang again..........
    Set off for home, and all quiet so carried on with my short drive.
    After 2 miles parked up and crawled under.
    Right hand side CVs cold and hub/disc cold.
    Left hand side inner CV cold.
    Outer CV and hub hot!

    So either the new CV with 2 mins use on it is defective, or the wheel bearing may have been the culprit all along?
    Anyone have any ideas what causes the load bangs?

    Anyone have any idea what bearing is in the rear hub of a Corse I, and how difficult to get in/out?

    Ta

    Are you sure it is nothing to do with brake pads, usual cause of things getting hot around hubs.

    Re: Corse I CV joints

    Is one cv plunging to its limit and a ball popping part way out? What are you using to limit the plunge?

    There are no limits on the shafts to stop excess plunge. The shaft goes in through the gaiter, through the bearing and then a circlip goes on to stop it all falling out.
    This is the same both ends of the driveshafts, both the inner and out CVs.
    I have checked and now limited the droop, so that at full extension there is still side-to -side movement, so that the circlip is not trying to pull on the cages.
    I have also jacked up the car and spun the wheels when at full droop when holding and pushing the driveshafts fully towards the gearbox, and fully towards the hub to see if any noise,contact etc. All negative.

    Will now look at those, but what would be the loud bang and feeling of big knock to the car?
