Lotus Elan

Metallic rubing noise when turning right

PostPost by: Niklas777 » Mon Sep 18, 2023 7:44 am

Hello,

I'd like your opinion on a strange noise on my 1967 Elan S4 SE.
I have a metallic rubbing noise (difficult to describe in detail) which only happens when I turn right at a fairly steep angle.
As the speed increases, so does the volume of this noise.
The rear brake discs are new, the front discs are recent.
Do you know where it could be coming from?
Thanks

worn rear bearing or loose front bearing allowing disk to contact caliper ? or rear rim contact A frame bolts ?

I have had all the bearings checked and they seem to be fine.
The rear rim though is an issue.
I had the A frame grinded but it could be that there is still a clearance issue.
The noise seems to come more from vibrations in the floor panel, but it could be that the vibrations are spreading.
Hard to tell.

Could it come from a geometry issue? I don't understand why it happens only when turning right, and no issue at all when turning left...

If it’s a vibration could it be the exhaust catching somewhere as the engine moves on its mountings? Are the engine mountings good (not collapsed?)

This is a very good point. I have to double check that.
