Actually - I have to chime in on this one. All good points were made, but
I strongly recommend that no matter what you do that you replace the upper
a-arm bushings in the front with polyurethane or harder material.
The original upper a-arm bushings can get nasty fast. Virtually every TR6
that I work on or look at for folks has most or all of the upper a-arm
bushings "perished". Sometimes the perish within a year or two (depending
on the condition of the upper a-arm fulcrum pivot bracket).
At any rate, it is worth considering the poly-u upper a-arm bushing no
matter what you do with the rest of the suspension.
As a point of reference, I have poly-urethane all around on both my TR6's
and they are not overly harsh. They are firm, but not harsh. And I drive
my street car a lot.
Also note, with the inner lower a-arms in the front and the lower
trunnion bolt and the rear trailing-arm bushings, there is a steel sleeve
that goes through the bushing. You should at the very least use some
anti-seize on the bolts so the sleeve doesn't rust solid to the bolt (and
cause squeaking).
