John,
Several years ago on an Asian vehicle, I had the same problem, and I finally
tracked it down to the plastic hub cap flexing, as the wheel rotated under
load. Although the "6" doesn't have a full hub cap, it does have trim ring,
and the small center cap. It may not be the source, but when the wheel,
rotating under load, flexes, the springs in the trim pieces can "tick" as
you described. to check if this may be the source try removing both the trim
ring and the center trim from the offending wheel and see if the "tick" goes
away. If this proves to be the culprit, sometimes a spot of lube on the
offending spring takes care of this. If not there may be the possibility of
the wheel itself flexing and the noise being magnified by the structure of
the wheel itself-(minute cracks in the mounting area of the rim)??
may not be the cause but it is worth a try.

Dear Listers,
When driving my 74 TR6 at low speed alongside a wall, I can hear a
tick-tick-tick sound coming from the wheels. I think it's the right rear,
but not sure. This has been going on for some time.
Last year I replaced the left rear hub with a rebuilt unit, mostly because I
had a considerable amount of lateral play in the bearings. But the
tick-tick-tick continued.
Recently, after discussing this with some friends, I decided to rebuild the
brake hydraulics all-round, on the presumption that the front brake caliper
pistons were not receding into the calipers. This may very well have been
the case, since the pistons were very rusty and gunked-up with crud. I
replaced them with stainless, flushed the lines, installed new rear wheel
cylinders and master cylinder, and converted to Dot-5 brake fluid. So
everything is working wonderfully as far as the brakes go. But, I still hear
the tick-tick-tick when near a wall that bounces the sound back to my ears!
Could the bearings in the right-rear hub be doing this? I don't want to
change this unless I'm sure, because the replacement hub is expensive!
Any ideas?
Best regards/John Truttman/Santa Cruz
