I am about to install the new Cinnabar bearings, hubs and knuckles in my
Transmode. However, I've not been able to find locally (Chattanooga)
either the Redline CV-2, Amsoil or Mobil One synthetic greases that have
been recommended by different folks to pack the bearings with. I can
get a Valvoline product call SynPower Synthetic Grease (part no. 985)
that is described by Valvoline as "Superior high and low temperature
protection (-65 degrees F to 420 degrees F) for all US...vehicles.
"Race proven." NLGI GC-LB. It is "moly -fortified" and is an NLGI #2
GC-LB Grease. What say you guys---is this just hype or could this
grease be suitable for the GMC? Any comments will be appreciated.

I'm no expert on this stuff (but I memorized what an expert said)...

The above quoted sentence is marketing talk... if the drip point is
above 400 degrees and you have to do it without one of the
recommended brands, consider shortening the service interval.
When I think about the hassle of doing it more often than 25000,
the price of next day delivery service sounds cheap.

Thanks, John. I thought a higher drip (drop) point was better than a
lower one.....that it indicated a better resistance to thermal breakdown
or something like that. Have I got this backwards?

Thanks, Manny. I may be able to get the local Auto Zone to order me some Mobil
One grease. But I'm still wondering if the Valvoline Synpower Synthetic
availabe here at NAPA might be equivalent to Mobil One.

No you've got it right... I was just reacting to the fact that the
marketing department could say from -100 to +500... you're
protected, without the drip point being over 400.

I realize what you are saying, the specs for your grease may be
equal or better than one of these 'recommended' ones, but I can't
help with that judgment. There are people here and web pages that
can make that determination thou...

Regards and feeling your pain ,

That's what I thought, Arch. I see on the Red Line website for their CV-2
synthetic grease that the drop point is claimed to be "900+" with the "useful
termperature range" shown as" -100 degees F to 500 degrees F " . I guess there
are some real differences in greases since Mobil 1 says their drop point is
550 degrees F and the "operating range" is -35 degrees F to +450 degrees F
.

Phil any of the synthetic greases will do the job. If your bearings get to
450 degrees than something is wrong anyway. I notice on my front bearings
even after driving at speeds in the 60-70MPH range for several hours both
the bearings and the tires are cool. Wasnt this way before I changed the
bearings and used Mobil 1.

Just a thought.

Thanks, Tom. That's what I was looking for----a first-hand report of experience
with Mobil 1 in the front wheel bearings.

I've been wondering how hot the bearings might get from the heat build-up with
heavy breaking on long down hill runs. We've got a few of those here in East TN
and there's a bunch more out in the Rockies where I like to travel.
