David,
I know it doesn't look it - but those original brass/steel sleaves have a
seam - that's very tight, upon installation - then they are reamed to fit
your cross pin. (RevigntonTR sells oilite sintered bronze bushes that don't
require reaming - but would be helpful to have exact size drift for
installing).
You might take a hack saw blade and cut opposite side of bushing seam (if you
can find it) to release it from the arm hole. You are lucky if they weren't
worn through ruining the casting - while they are out you might want to check
yours against the factory manual specs to see if they need straightening.
They are easier to bend than one might think - just hit a curb or two. I'm
still undecided if the original brass or these harder porous bronze bushings
will be better.
Regarding the steel sleaves on the inner lower pins - when you are dripping
sweat from using MAPP gas (hotter than regular) in you propane torch and
wrangling like mad with your big vice grips - the sleaves will be easy to
remove! A little break in between each one seems a requirement. And putting
ice on the threaded pin end was part of the strategy: 'make the sleave expand
with fire - shrink the pin with ice' (or at least not ruin the pin!) ... it
was successful but a rigorous workout.. the new sleaves went on easy.
Good luck,
Carl

Subject: TR4 Control Arm Bushings
Here's one for the list...
Has anyone ever replaced the lower (outer) front
control arm bushings on a TR4? These baby's are stuck
(press fit for 40+ years) and they are very slim (not
much to press out)...
I'm thinking of a drill press right about now.
Any other thoughts? If I had a hydraulic press with a
perfectly fitting drive pin I might be able to budge
the things but with conventional tools I am
struggling.
One other question is related to the metal sleeve that
rides inside the nylon (inner - lower) control arm
bushing. The old sleeve has fused itself to the pivot
shaft so well that I think even a nuke might not get
it off and in the process the entire shaft would
probably come with it. At this point I am thinking it
will be fine to leave the old sleeves (worn) in place
with the new nylon bushings over the top (pig in a
blanket)! Thoughts?
Any suggestions very welcome at this point.
