Help with rear trailing arm bolts Options

[sixaddict]

Car was aligned and corner balanced .....At track discoverd 3 bolts attaching @ front of trailing arm were "tight" yet arm was shifting. So bolts are tight but arm sliding back and forth....Really "interesting" under heavy braking after high speed straight...... (IMG:style_emoticons/default/evilgrin.gif)
I am sure someone can tell me what is up and how to fix..
Thanks

Pull out 1 bolt, measure the depth of the hole it's going in compare to the bolt. .
The cheating fix is add a shim plate on top of the factor top plate but I'd only do that as a temp thing. . on older 914 the bolt hole went all the way through. . I seem to recall that later cars they didn't. . if that looks all ok, amybe there is wear problems in the pivot bushings

Jack up the car, grab the wheel and see which way it wiggles. . . I'd look at the ears for elongated holes, the inner ear is cracked and flexing, or the bushings are worn out. .

When you cant' see the trouble, you'll need to pull it apart. . unfortunately that mean loosing the alignment settings. . and if any of those things are worn, it will need realignment anyway.
