Front uppper ball joint.

[Blaster]

I have some play in the upper ball joint that I think is causing a clunk when hitting the many pot holes in roads near me.

Looking at it, it seems familiar to the ones fitted to the front of the triumph 60's cars. Herald Spitfire Vitesse and GT6.

I have looked through the forum and the wiki to see if any has compared them as they are less than half the price of a Lotus one.

So do I order a Triumph one or the Lotus one?

Tony,

This was first talked about many years ago, somewhere on the forum.

I think that it was considered that it would be "okay" but the dimensions need checking. I seem to remember something about it being wider in the body (or narrower!) - either way, the number of shims to adjust the caster were different.

I don't know if the taper is the same to fit in the upright/hub, or if it allows the whole geometry to remain the same (the same taper could still sit either higher or lower in the hub).

Another consideration is the size of the holes - Triumph balljoints will use Imperial size holes for the bolts, not metric - so something may need to be drilled to fit it securely.....

.... overall, I have no personal experience, because I decided to just pay the money and buy the "proper" items and avoid the doubt.

Cheers I will order the Lotus ones now.

IIRC, a long time ago this was looked at and the conclusion was that the old triumph part wasn't compatible
