Urethane redux and a question about stub axels

Hi Everyone,

About a month ago I posted a question about using urethane bushings in place of the steel/nylon replacement bushings on the lower inner control arms of my TR3 and I promised an update as things progessed. First, thanks to everyone who responded!
As it turns out, only the left inner pivot pin was worn, about 0.057 inch relative to the other pivots and the inside dia of the steel bushings. It appears otherwise OK. I used the Prothane upper wishbone bushings carried by Moss. They fit perfectly and everything went together well. The resulting assembly is rock-solid and moves very smoothly.
<span style="font-weight: bold">HOWEVER</span> when I went to install the wheel hubs onto the new stub axles (axels and wheel bearings from Moss) they would not fit! The axel diameter is just slightly too large (or the bearings are slightly too small!). Has anyone had a similar experience? Are there newer bearings I should be using? I bought the axels about a year after buying the bearings. I would much sooner replace the wheel bearings rhan tear everything down in order to replace the axles.

Comments/suggestions?

Hi John-

No direct solution to offer, but you are talking about the stub axle and wheel bearing, right? I've not heard of reaming out the bearings before, the only place where I think this is needed is on the lower outer bushings /trunnion pins.

If you are having trouble with the stub axle and wheel bearing, this exact problem came up a while back, maybe 6 months ago. I thought it was Julian who had the issue but may be wrong - a quick search will turn up the topic and solution. Sounds like there may be a slight problem with the replacement stub axels being oversized.

Found the link, it was Julian: stub axle issue

Not sure how it was resolved - but if you can't persuade the bearing on I'd consider returning the axle as it sounds like it is oversized.

Hi Randy,

Thanks for the link. A few minutes with some emory cloth and the bearings went on (and came back off!) without a problem.
