Hey there

The title says it all, I installed new adjustable arms and they seem slightly pointing backwards after connecting it to the caster rods/arms. Which made me wonder and ask for advice here!

What I did:

- Install polybushings on the inner bush of the arms
- I tried to aim for the length of the original arms for later adjustment.
- The arm is not connected to the upright yet

Both arms point consistently backwards





So, am I just worried about something that is totally fine? How do yours look?

Grazie mille
Alessandro

Possible a PO dealt with shot caster arm bushings by lengthening the caster rods?

The Caster Bushing looked fine to me. I only changed the arms because I wanted adjustable ones. I also compared size and distances of bushing to bushing and they seemed all the same.

Can I assume then that the push-back is not normal? The arms still move freely btw.

Is the inner bushing centered in the pocket?

Ultimately, it'll be what the alignment rack that tells you that matters.

Have you compared the outer ends of a new and old rod to see if the caster bushing ring has the same distance and angle from the ball joint?

I will recheck the all the distances, to make sure. The inner bushing is centered and fits snuggly into the hole between the two plates.

I am also going to install the old arms temporarily to see whether the PO had the caster setup like that.

Thanks!

If worse came to worse, [SARC] you could always take it to an alignment shop and have it all checked (caster, camber and toe). New adjustable control arms can throw the camber off unless adjusted to the same length. Always advisable after a suspension rebuild. Specs in the OM.

PS: I had an Alfa with different length caster rod adjustments and upper arm positions because some PO hit a curb and pushed the whole right side back. That unequal adjustment was required to get that side correctly tracking.

Hey @Anfanuts

I setup the controls arms just as the fixed ones, so i can start from where I was, which wasn't particularly bad. Each side is equally caster-y and thus i think it was intentional by the PO. Still I do wonder - what does this caster do to the life of steeringbox and bushings?

a lot of people crank caster into the front end... sometimes for damage control, but mostly to increase front grip. more caster adds neg camber dynamically during turns -and then goes back to static camber when wheels straight ahead. will increase steering effort and give more "snap back" to straight ahead wheel position when come otu of turn. put together and then take for front end alignment. very worthwhile on any car that has not had it done in awhile.
