Dear Joe,

Now that is interesting.   I rather truncated my description of what I 
did yesterday - here it is in full:

Removed nut (five minutes - rusty as hell)

Attempted to push bolt out from the rear using my fingers (one minute - 
impossible)

Squirted WD40 all over it, and attempted to tap bolt out from the rear 
using a light hammer (ten minutes - impossible)

Attempted to drive bolt out from the rear using a four-pound lump hammer 
(half-an-hour - impossible)

Cut the head off the bolt with an angle-grinder (four minutes - fiddly)

Attempted to drive bolt out from the front, using a four-pound lump 
hammer and punch (one hour - impossible)

Attempted to drill out the bolt from the front (fifteen minutes - no 
significant progress, as the bolt appeared to have been made of depleted 
uranium (presumably I had work-hardened it nicely with the punch))

Attempted to hacksaw my way through the bolt inside the bracket on the 
lower wishbone (one hour - impossible and tending to cause bad language)

Attempted to use a hand-held woodworking jigsaw with a hacksaw blade in 
it to cut through the bolt inside the wishbone bracket (thirty minutes - 
impossible)

Had another go with the lump hammer and punch (three-quarters-of-an-hour 
- impossible)

Cut the protruding portion of the bolt off with an angle-grinder, 
wiggled the whole assembly until the trunnion swung free, removed the 
remains of the bolt, distance piece and trunnion bushes from the 
trunnion with no further effort whatsoever. (seven minutes)

Fitted new parts and replaced road-wheel (three minutes)

I have had a few off-list replies which suggest that a garage would 
simply have cut away the seized sub-assembly and fitted new.   At best 
that would have meant a new trunnion, and at worst, probably a new lower 
wishbone as well.   Checking the price lists shows that I saved myself 
about GBP25 for a trunnion and about GBP50 for a wishbone.   I'm not 
entirely convinced that all the effort was worth it.   Still, the 
exercise did me good, and I'll know to get the angle-grinder out earlier 
next time!
