    Default Rear Wheel Alignment for 504 Rally Car.

    At the tyre shredding Jenolan Rally my rear tyres were wearing out the inside edges leaving the outer edges almost brand new.
    So I was thinking it would be a much better car if I could even out the wear across the tyre .
    My first thought is to change the rear wheel toe-in. The 504 does not have any toe adjustment , so I am going to machine the rear wheel bearing carriers, the question is how much toe-in should I aim for as need to decide before sacrificing a wheel bearing carrier.

    The camber is about 2degree negative and stays fairly constant thought the working range of suspension travel.

    What settings do other cars with similar trailing arm suspension use?

    Have you bent the rear beam? I think I have heard of them bending.
    Present fleet:-
    Peugeot 93' 205 Gti 16v
    Peugeot 73' 504 Ti from new
    Peugeot 08' 407 Hdi Coupe from new

    Previous fleet:-
    Peugeot 95' 605 Sv
    Peugeot 92' 205 Gti
    Renault 72' 16TS from new

    Hi Andy, you can't see what I'm doing with my hands but are you sure it isn't caused by too much neg on the rear rather than toe? As BIGRR suggests is worse as if the beam bends down in the middle I think Thanos puts a fillet of flat in the beam to keep it stiff.

    Cheers

    2 degrees is definitely more than standard and yes, they do bend.

    2 degrees doesn't sound a lot to me given how a 504 squats but I'm surprised it stays the same throughout the travel as I thought they got more neg the lower down the rear was?

    The rear of the Pathfinder is very subject to camber and will wear an edge, particularly with a bit of positive. When it has a bit too much toe, in or out, it seems to wear across the whole tyre rather than on one side.

    Very close to straight trailing arms rather than semi trailing as in BMW, Commodore.

    I usually adjust camber on 504, using shims in the appropriate thickness, on the 4 screws, it is possible to adjust toe-in with it too.
    It only takes a few minutes on each side.
