Bent trailing arm

Post by Dougieboy1 »

in the final phases of finishing resto of 72S.

During final suspension set up, i have learned i have a bent trailing arm from a prior kerbing.

Can they be straightened and if so, who can do this?

thanks

Not at all sure, but I think Tuthill's have a jig to straighten their rally car suspension parts.

Hi Andrew

Sorry I don't have a solution, just a question - how did you determine that the existing (original steel?) arm was bent? Obviously I'm assuming it's not a major contact you (or PO) had, and therefore patently obvious?

I suspect my aluminium replacement (I'm planning to upgrade the exiting steel arms on my 1972 hot rod) arms may not be 100%, and of course I don't have a jig to determine with absolute accuracy?

Many thanks
Magnus

.

I'm fairly sure that Chris Flavell (fetuhoe on DDK) at Fenn Lane Motorsport has a jig & facilities to straighten steel arms ...

As mentioned above, Tuthills have a jig and offer this service.

thanks all for the pointers.

Magnus, it was not discovered until all bolted up and the rear suspension geometry could not be adjusted correctly. The assumption is therefore that the arm is bent given i know there are no issues with the shell.
