Guys, er, excuse me...geniuses!
I wanted to take a minute and thank you all again for that advice.
After draining the "god only knows what" from the transmission
I refilled it with "real" 80/90W. Cured a bunch of growling (except from
me when I had to pay for three buckets of the stuff at $53 ea.+tax.)
in the tranny at high speed (around 30 in high range/9)
I also find that I can now go in and out of 4WD (at will!) without
having to sacrifice a
goat and wave a dead chicken over my head three times. it was stuck in 4WD
before. Shifts high/low range easier too.
Amazing what "real" lube will do. Remember this machine has only 280 hours
on it, but it's 11 years old.
For the record...what came out of the transmission and differential was
goose-poop gray/green, and thicker than pancake batter. It took 5 hours to
drain 10 gallons through a one inch dia. hole.(Yes, really...in 70F
I then flushed it as best I could (no filter on this one) with four
gallons of mineral spirits through a suction
gun, over and over again, to get rid of the (estimated) inch of dreck on
the bottom of the case. And oh, did it stink. Worse than skunk cabbage
It must have had a serious algae problem. The front axle and drives and
transfer cases were all dark
brown/black oil that smelled like 80/90, so they were ok...no trouble
Changed them anyway.
I'm not even going to attempt to reclaim whatever it is...it goes
straight to the recycler.
And good riddance!
But I did want to tell you all how much I appreciate all the advice...it
helped a lot.
