Since you have the old shafts out of the trunnions. it should be a "piece of
cake" to simply turn the pivot part of the shafts down to a suitable size to
"sleeve" them with a bit of tubing. Then turn the sleeved shafts to spec and
you should be "back in business". I did this years ago with my TR3, so I know
it works (and is an easy and cheap solution). I have since replaced them with
a set of "Runion's Trunnions" due to excessive wear in the acme screw portion
of the trunnion (too much "wobble" in the vert. shaft).

Subject: TR3-4 Front Suspension Rebuild - another question
Listers,
I was looking at the bronze trunnion from my dismantled LH front
suspension. The old trunnion is a "Brit Part" and looks to be in
very good shape except for the shaft which is all rusted and
pitted. The new "Taiwan" trunnion casting and shaft from TRF is
not up to the same quality level. There are some machined cuts
on it that are unfinished and I will have to grind away some
flash to keep the oil seal from being torn up. There is also
some misalignment of the drillings... the center hole is off
center a little.... so that when the ends are cut on either
side... it makes a incomplete ridge for the oil seal. This
condition exits on the new LH and RH trunnion.... as well.
Don't get me wrong... I am glad that TRF has these replacements.
If mine were toast, I would gladly use them. But I was wondering
if there is a source for new Trunnion shafts. I have a press and
already pushed out the old rusty shaft. The TR parts catalog
does not show a part number for the shafts alone. If I can't get
new shafts... I am almost of a mind to swap the new shafts into
the old bronze body.
What do you guys think?
Thanks in advance... any and all advice will be appreciated
