Most likely a cracked diff mount which is very common. Normally the right
front one is the first to go. When mine went, my wife said it felt as if the
noise was right under her seat. Usually an experienced welder can fix them
with out too much trouble. About half way down this page
(http://tr6.danielsonfamily.org/DiffMounts.htm) you'll see the cracks in
mine that caused the clunk........and I only found these after doing some
serious work with a wire brush i.e. they don't have to be big obvious cracks
to make noise. I ended up boxing in the front and rear to eliminate any
future problems. The axle splines can also make a "similar" noise.
There are far better reasons then a broken diff mount or noisy axle splines
to run away from a TR6. I'd focus on frame rust, TA attachment points,
tee-shirt area and body rust.

Subject: [TR] TR6 Rear End Clunk
A little help from TR6 owners please. I have a TR3 and a TR4 but lately have
been looking to purchase a TR6. I recently looked at one quite a distance
from where I live but have a concern about a clunk in the rear. When both I
and the owner drove it, there was a mild clunk coming from the rear when
engaging the clutch from a standstill and when I drove it, sometimes when
shifting gears just before engaging the next gear. It seemed similar to what
I have experienced when one of my cars needed a new universal joint. The
owner indicated that he understood from other TR6 owners that "...that was
the way TR6s were". He tells me the universal joints and the differential
mounts were replaced . From what I have read, this might relate to worn diff
mounts that lead to cracks in the frame where they mount. Since the diff
mounts were replaced, it shouldn't be worn diff joints. What is the wisdom
of the list relative to this rear-end clunk?
