1iTim's triumph miglia special

[1iTim]

i have a problem. (ok not just one but lets start with that!)
My left rear upright wont come off. The lower bolt that joins the hub or rear trunion is stuck inside somehow to the bush or something.

I've tried wd40, I've tried a hammer, I've tried both together, I've then tried blowtorch until its all smoking then the hammer.

All I have succeeded in doing is deforming the bottom of the bolt with all this banging. After hitting the bolt (lots) the bolt head is a mm proud, but the top of the upright spreads to about 90mm from its restful 80. I dont want to damage the upright.

Any advice or hints on removing this bolt?

(as an aside, which front stub axle assembly goes on which side? the normal trunion thread on the right hand side, and the left hand trunion thread on the left? or the other way? I had not labelled them before i realised they are "handed")

Hi Tim

There is a small space either side, between the trunnion and the vertical link containing the flanges of the plastic bush and the thin tinplate dustshields. Hacksaw through the bolt either side of the trunnion through these. This allows you to separate the trunnion from the link and gives access to the rest of the bush inside the trunnion. Then you can remove the bush by a combination of melting, drilling and/or pressing. New bolts and bushes will obviously be required for reassembly!

The new bush kit looks like this

The right hand threaded one goes on the right hand side and vice versa.
