Ok. Have you guys had any problems with the RP trailing arms adjusting themselves in (shorter)? I know there is only one lock nut which is on the heim joint end of the arm. Is tightening that one onto the blue section enough to keep it from adjusting or should I add another lock nut on the rear end of the arm? Maybe the heim joint end lock nut just isnt getting tight enough... I dont know.

 

A locknut at the rear of the arm will do absolutely nothing.

 

Are the Rp trailing arms and toe links solid aluminum or are they hollow?? sorry for being off subject.

 

J,
whether the locking nut becomes loose of course depends on how tight it was to start with. i have never had one loosen and i just lean on the nut w an open end wrench. should you wish to have additional assurance my suggestion is to coat the threads w RTV silicone adhesive, then retighten it.

Thanks guys...

My main concern with having a rear locking nut was due to the fact that without one there is a little play in the trailing arm itself where the rear threading enters the blue part. I was concerned about over time with that play if it would eventually fatigue the unit and cause any sort of failure.

And yes I assume that was the problem. Had it aligned and naturally they were supposed to tighten the bejesus out of it but I suppose they didn't.

I decided to add a rear locking nut for stability at that joint. may do nothing, but it can't hurt anything either.

Thanks again for the help guys.

 

If there's any play there and the bolt is tight then it's the pillowball that is moving, not the trailing arm.

 

i have the M2 trailing arms which are basically the same thing. I had some play afterwards but it's was the bushings like damon said. Replace those and it's all gravy after that

 

Bushings were replaced at the same time trailing arms were installed. I'm at work and the car is at the alignment shop and the mechanic is the one telling me there is play. So I haven't had a chance to see it personally. But I just spoke with him on the phone and he said putting a locking nut on the back end stopped the play. So it stays.

 

Post a picture of what he did. I don't see how it could make a difference.

 

ok one day when i feel the need to jack up the car again. it's been jacked up and down a million times over the last 2 weeks. i may feel a need today. who knows.
