Rear suspension arms, repair or replace?

Postby adie89 » 21 Aug 2018, 16:16

Advice please, I went to replace the spring seat on my trailing arm that is out to replace the mount and found this

So the question is:
1. Repair - I’m reasonably confident in my welding that I can put a flat section of 3mm steel in.
2. Replace because I shouldn’t repair it, with a pair of 14 trailing arms
3. Upgrade to 16” arms but, a. Is it worth it for the extra wheel options, b. Do I need to replace anything else for 16” parts for them to fit? I think I remember syncrodai saying he moved his arches back but I’m not sure if that was for the 16 arms or just for his wheel choice.

A spring seat repair panel should be fine in there. Buy em from brickwerks, schofield etc. Can't comment on the 16" arms

Remove the bushes and inspect in and around the sleeves. Both bush areas prone to rot but the outer seems to get the worst . Then you will have the full picture . Decide from there but last time I checked brickworks all-in package seemed very reasonable

Cheers gents, I was concerned because the arm is supposed to be 3mm thick and it’s completely broken through.
I already have the spring seat repair panel, it was the prep to fit that I found this horror.
I have looked at the bush mounts and oddly from what i’ve Read that agrees with your advice on the outer rotting, my inner is in worse nick. The outside of the mount has corroded quote heavily

Does the German TUV allow swing arm mods ?? 14" arms are easy to obtain, same as 2wd.

Probably not, a lot is a case of what they find. Generally it’s a lot easier if they a very parts of a different version

Push the bushes out and get the whole thing blasted.
As Jez says, sleeves perforate.
Might find it turns into a teabag and not viable to repair. Would be a shame to fix spring seat only for Bush ends to be dead.

Thanks for everyone’s input, based on everyone seeming to think it’s just the spring seat that’s buggered I’ve ordered new ones. This is because the metal on the actual arm under the spring seat has corroded through completely.
