Converting to rose joint track rod ends.
John Bonnett - 13/7/20 at 07:05 PM

Just an option I'm thinking about. Should the taper in the steering arm be bored out to parallel?

Pretty sure I’ve seen an adapter the has a taper to fit the steering arm with a stud at the wide end of the taper to attach the rose joint?

I've looked at a few Escort kits (which won't be any good for me) and they appear to have just an h/t allen bolt to fix the rose joint to the steering arm. I wouldn't be happy to fit a parallel bolt into a taper.

Just remember forces on the joint, rosejoints are not strong when pulling then ball out of the socket..

It's a well used conversion on rally cars so I would have thought it would be okay.

Perhaps a thick shouldered washer would do the job?

With a straight bolt into a taper it's only going to touch in the tight part so surely it has to flex where there's a gap.

How about machining a tapered item to fit through the steering arm with a securing bolt holding it all together. ?

I think that would be a good solution although simpler to drill out the taper in the steering arm to parallel.

Made me think a bit this one. I was wondering why most track rod ends are tapered. I suspect the answer is to provide a second fail safe if the nut comes undone.

I suspect a straight bolt and a nut with wire or a split pin would do the job. That said I would probably machine up a taper with a straight section then threaded ends. Just feels more elegant. you may well need to build in high alignment busshes/joints as a standard rod end has quite limited missalignment. A safety washer at the top in case the ball pops out (pretty unlikely in my view the load will be tiny).
