  • Bottom steering tailing arm ball joint

    Hi all looking for help, n/s/f bottom trailing arm knocking, on the face of it king pin to pull out from the bottom, wishbone bolt to remove and then 2 nuts, couldn't separate the arm from the stub, stripped further, stub removed, still won't separate, the head of the bolts / stud have a Allen key but I can't budge and the new part is not threaded, any body any idea how it comes apart. Got pics if needed

    Just did this last night on the rally car. Those two studs with allen key heads - they are splined where they go through the arm. We put the nut on, left a few mm gap, put a socket over it and bashed it with a 2lb hammer. takes a fair bit of vigor but it will move. As it moves, back of the nut to give you more room. For the last bit, use a drift punch. The king pin is on a long spline as well. Best to take the hub of and remove the bearing so its easy to work with. Take out the torx screw for the king pin, then a slide hammer attached to the centre thread on the king pin - 8 x 1.25 I believe - will extract it.
