replacing gear oil

[twitchee2]

so about 45k ago when i did ALL of my fluids, i put royal purple gear oil all the way around. I have sense changed the rear becuase i dunked it before i did a diff breather, but i have no touched the front diff or xfer case. should i change those two now or wait another 10k to when i hit 200k? I think im gonna do the rear cuz i put the cheap stuff in it and it was about 30k ago.

just looking for opinons here, not to sure what i should do

Gear oil really does last a long time. I wouldn't sweat 10K miles.

I just changed the diffs and transfer case fluid for the first time at 140k, honestly I don't think they were ever changed before. You should be fine.

Heh heh - I just changed all 3 today. I know it's not necessary but I do them every year for some reason. I finally found a small trick on the fron drain. I put the truck on ramps which gave enough extra clearance that I could undo the plug with a breaker bar. That drain plug has caused a lot of cussing every year. I have put anti seize on it and torqued it the factory spec and I swear it seems like it is set to 100 ft lbs the next year.

You're doing it way too often haha. Save up some of your money dude, do it every 4-5 years.

Agreed, I'm running Royal Purple in mine as well and another 10k is nothing as long as there's no water in it.

If you have contaminated the gear oil, I would replace it right away. Just replace it with whatever gear oil you find at autozone or advance, then don't worry about running the clean oil 10k more before you change it enough next time.

A word of advice: loosen the fill bolt first with a 6pt socket, not a 12pt.

Very good tip.
