    Rear Camber Angle

    Hi

    Had new rear tyres put on car today (2008XK convertible, 45k miles, 20" sentas)) and had a 4 wheel alignment done at the same time. Bearing in mind that both rear tyres had worn evenly I was surprised when the rear offside camber angle showed as being outside limits at -1degree 38. The nearside was spot on.

    Has anybody any suggestions what could be causing this or, as the previous tyre wore evenly, should I actually bother trying to find out at the moment. Also, if I did do anything should I do both sides bearing in mind the nearside is "perfect".

    Thanks

    Strange they didn't have any suggestions of what could be wrong!?
    Can't help you more then if they wear evenly I would drive on and keep an eye on the tyre.

    The rear camber spec is -0.53 degrees +/- 0.75 degrees, so your reading is just slightly out of spec. You probably know that rear camber is not adjustable, so if you wanted to fix this then you would have to look at the bushings for the upper and lower arms and see if any were sufficiently worn so that you would have a clue that they needed to be replaced.

    My sense is that this is a very low priority issue since you have found that the tires are evenly wearing.

    the rear camber is adjustable, so it should be possible to rectify relatively easily. The upper arm pivots on eccentric bolts

    1. Have you had an opportunity to make this adjustment? The repair manual asserts that only rear toe is adjustable. (page 141 out of 4,000)
    2. If rear camber is adjustable then the alignment shop presumably would have attempted such adjustment...

    Hi

    Thanks for this - the rear is non-adjustable

    Live with it. Not a big issue, especially if the worn tyres came off worn evenly.

    Well, page 250 of the repair manual says "Note the fitted position" with respect to removing the rear suspension upper arm.

    Then page 252 says "Align to the position noted upon removal."

    So that does imply that rear wheel camber might be possible...
