    Careful you don't snap them - they often corrode into the case. You will have a world of pain then . . .

    I would mix diesel with some thin engine oil,
    30% engine oil & 70% diesel .
    Apply to the bolts & bolt holes where possible, leave to soak in overnight at least,
    longer if possible.
    Re apply so as to get as much lubricant in as possible.
    Be careful were you go with the diesel as you probably know it will destroy most types of
    rubber .

    Thanks for the tip
    I will lubricate daily for the next days and then retry.

    Really unbelievable, impossible to loosen the bolts.
    Only option is to remove the disc calipers and discs and try with airtool because otherwise there is no space to move the tooling.
    If this isn’t working, next option is the grinder!

    The problem I have with this assembly is how repeatable is it.
    Even if you disassemble the individual parts and reassemble would you end up with the same values. Even tightening the upper bolts before the lower ones could twist the whole axle, increasing toe on one side, decreasing on the other.

    And how can you measure it without fully reassembling and putting on a measuring machine.


    Wonder how how accurate these were set up when the were originally nailed onto a Jaguar saloon way back when. Did anybody even measure rear toe then?

    Coupled up with the oil and diesel solution.
    Just be aware of potential ignition though .
    Make sure you have some form of fire extinguisher to hand .
    I am suprised that it hasn't already shifted with what you have already done!
    Don't give up, time and patience as they say .

    Just looking at the original post to work out what needs to be done to correct the toe (I can't offer much help getting the bolts out)

    You indicate "-0.14 and right side 0.28"
    I'm assuming this means toe in on the left and toe out on the right? So you'll get a bit of help on LH bends but it'll work against you on RH.

    What value are you aiming for, can't remember what is suggested by GD.

    I've had a look at my spare diff', the mounting bolts for the pivot brackets are 110mm apart. Looking at the RHS as it has the biggest error, that would mean you need to add 0.54mm of shim to the rear mount (or remove the same amount from the front but I'd not expect there to be that much in there.
    That seems like a heck of a lot so someeone please check my math's

    The holes in the front and rear brackets will need to be slotted by to allow the pivot shafts to fit.
    But why is this so far out? Was it OK before but wrong now or has it always been wrong? If it's gone wrong since modifying the lower arms then perhaps that job wasn't done so well.
    If the problem is due to the pivot centres being wrong I'm surprised the GD brackets fitted over the pivot shafts in the first place.
