4×4 Front Axle lube problem!!

Matt, There don’t seem to be any big leaks.. Just a very small amount of oilness near the seals. I had a suggestion that the axle areas don’t get drained well, and so I will try jacking the truck side to side on the next drain cycle. Actually my yard is plenty hilly; I can just move the truck on a good side slant, one side and then the other! Anyone have opinions on ‘flushing’… ??

seepage is not unusual. >I had a suggestion that the axle areas don’t get drained well,
true enough, if i could throw a ’some’ in there? >and so I >will try jacking the truck side to side on the next drain cycle.
hehehehe i do this sometimes, depending on what i’ve had to replace, or change. >Actually my yard is plenty hilly; I can just move the truck on a good >side slant, one side and then the other! >Anyone have opinions on ‘flushing’… ??
i don’t know from IFS Chevys, but if it was a solid axle i’d use twenty weight, and make sure the axle and flushing oil were both warm: driven and setting in the sun, respectively. i’d drive it about a mile or two and drain it, refill with twenty weight. lather, rinse, repeat. refill with recommended oil.

Have a 92 GMC Yukon, (full size – 4WD, Auto as stock) Last Winter had troubled getting front axle to engage (both heat-actuator and a later motor actuator). Lubricant was drained and replaced and the stuff that came out was very moisture-ridden, cream color. Must have been in there 100K miles. Replaced lubricant, looked OK, actuated OK. Found the breather tube hanging where it could have gotten road water, attached it up high in engine compartment. NOW, today I decided, before Winter, to check the lubricant. It’s badly fouled again! Consistency, color of dirty cream. Still very slippery, but seems about 40 weight. YuKKK!!! Anybody else experienced this?? Any pointers or suggestions?? I just drained and replaced with standard 80W90. But, should I try to flush this with something?? I can do this myself, and wouldn’t mind a couple flush cycles. What would be good to flush WITH?? AT fluid?? Kerosene?? #20 motor oil?? I would expect to go run it for 5 miles or so, and drain it again… Hoping this rings a bell and someone else has dealt with this mess!!! I NEED this to work reliably this Winter or Walk… — Regards, Terry King …In The Woods In Vermont
