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......
I am sure someone can tell me what is up and how to fix..
Thanks

There is something keeping the bolts from tightening against the underside of the bracket. Perhaps the bolts were changed and have too long an unthreaded shank, or there is something inside the threaded hole (possibly rust or dirt) causing the bolt to tighten up before its fully against the bracket.
There should be a 3 hole plate between the bolt heads and the console bracket. Is that there still?
Who did the alignment? Did they use the correct shims? How many shims are in there? Has someone previously "fixed" a broken bolt issue on your car?
Shnorr washers are important to keep the bolts from loosening but that doesn't sound like your problem.
