    thanks Todd, am in the UK so probably too expensive to buy and ship vs straighten. If i find i cant straighten, i will get back in touch.

    Frank would know (yes, that Frank!)
    My trailing arm was bent after a trailering accident and he found me a replacement after a while. I would think he would have straightened it if he could have because it was hard to find one. Hope this helps.

    My guess would be , yes. If it is just slightly askew, it might adjust back to spec. I would contac a Porsche dealer as they may have a go-no- go fixture to check it. I have often wondered if this would be easy to have done ( someone with the fixture, tool ) or are all the old tools/ gages no longer around. Hope you have a good outcome. ....cliff

    I know if no one who has successfully straightened a bent trailing arm. Come to think of it, I know no one that has attempted it.

    Regards.

    I was trying to be optimistic. My bigger question, is there a gage to determine if a trailing arm is out of wack before installation?......cliff

    Yes, there are factory jigs that are used to check trueness. The jigs weigh a ton and are very bulky. I used to have all of them.

    Long before there was “an App for that”, there was “a jig for that”. Amazing.
