Mark,
If you look around, you might be able to find two parts CARS for $600.
My friend and I found two rust buckets whose bodies were well beyond
salvage and we took both drive trains as well as a host of other parts
so we have a couple differentials. Check your usual sources of used
parts in Canada to save international shipping charges or look on some
Canadian British or Triumph Club web sites for used parts. Or look into
ebay or other places for used differentials to find one that is
inexpensive enough to buy and have shipped to you. You say $600 EXTRA
to have it shipped to you implying that the parts will cost more than
the $600 and that you will still either have to do the differential
rebuild yourself or pay someone else more money to have it done. While
you may be taking a chance with a used differential considering the
cost that you have outlined I would think you could buy more than one
and still have spent less money than what you have described as it will
be costing you. I am not well versed in rebuilding differentials having
never done the repair myself but in reading list traffic for the last
three years and read the archives as far back as they exist, I havent
seen a pattern of post which describe the differential as being
extremely prone to failure. Leakage is another story, but not failure.
Any finally, the disclaimer. Others will undoubtably have other
opinions so I reserve the right to be partially or totally wrong. Just
my two cents.
Cheers,
Aaron

Subject: Differentiation of different choices for differential
Oh gloom is me. I hear from the shop where my TR-6 is undergoing
repeairs that
my differential (original) is in a sad state. Apparently I have found
one of
the reasons that I have been oberving less dripping than usual under
the car.
Of course the differential is mostly empty. Apparently the bearings
are shot
(rust pitted) and it is quite loose. Lately I started to hear a
whirring a
rattling coming from the differential, which provoked the visit to the
reparist.
The conundrum is whether or not to replace the crown and pinion gears
(a
rather expensive item) as well all the rest of the wearables. The car
has been
driving very smoothly up until this noise has started. It probably
only has a
couple of hundred miles on the noisy part, most of them at very low
speed. The
mechanic tells me that some of the gears are a bit blue but have no
broken
teeth.
So the question is: can I just have all the bearings and seals
replaced, or am
I fooling myself and really must replace the crown and pinion too?
Alas the
money is a concern at the moment so I'd like to save the $600+ dollars
extra
it will cost to get those gears here to Montreal.
Should I just buy a used diff (if I can find one) and possibly end up
with the
same problems in a year or so, or just try the bearings and seals
approach and
pray for quiet?
Any experiences, opinions out there? I'm dropping by the shop in the
morning,
but other than staring and saying "Yup, that's a differential all
right" I
don't have a lot of experience with this lump to base a decision on.
Cheers,
Mark
