Actually, the thought crossed my mind. The fluid viscosity is the
obvious variable affecting VC performance, at least over the near
term, with shear resistance governing it's long term outlook.

Funky weather over the weekend prevented me from swapping
transmissions (Sat, Sun, never got above 22F, with a little snow and
freezing mist mixed in; hello . . . still October . . .), but as soon
as the weather co-operates I'm going to do so. Gonna need that AWD
soon by all indications.

At some point I will pull and clean the bad CD again, and then see if
I can some of our Mechanical Engineering/SAE types involved. (They owe
me anyway :-)

Well beyond what little I remember from Classical Mechanics in college
(been a long time; we were still using slide rules), but probable that
a sharp ME can calculate viscosity requirements based upon the VC
design, and engine HP.

If this leads anywhere, you guys 'll be the first to know.

Here's an update on my problem. Finally got it over to the dealership
the other day, and we found out what the problem is. The power steering
fluid is leaking out, and it's because the rubber seals have cracked on
the assembly. The dealer is suggesting that I totally replace the entire
steering rack assembly. He is saying that there is no fix for just the
seals alone, the whole rack has to be replaced!

Is this true, or is he just blowing smoke up my ...? Replacing the
steering rack will cost $1100 including labour, he says.

I was thinking of just topping up the power steering fluid as a
temporary fix.

Looks like that's going to be my solution for now. In another thread I
have now mentioned that it looks like the shudder had absolutely
nothing to do with my steering mechanism, it was caused by a loose
cracked exhaust pipe. Once that pipe was replaced, the shuddering just
stopped. So even though the power steering fluid is leaking out, it
doesn't look like it was as bad as I thought.

Hi Yousuf!

Yea, I wouldn't tackle the rack job unless/until:
1) The leaking fluid was making an intolerable mess, getting on the
exhaust and causing a stink, whatever, or
2) It was leaking to the point where you couldn't keep up with it by
topping off the reservoir when you do a fuel fill-up more or less.
Power steering fluid is cheap; manual labor isn't :-)

ByeBye! S.

Any chance you were heating up the center diff with the exhaust leak ?
This low speed turn shudder is typical of the viscous coupling getting
tight.
