Bump!

Hey matt, well or anyone else that can help me.

I recently put some 85w140 or something close to that, gear oil in the rear diff to help smooth out the lockright. Ive noticed the last two days that when i first start driving it, when i shift lets say to 4th gear doing like 35 it kinda lurches, (almost like the locker is locking and unlocking, but im not sure) then today while driving to work it dawned on me that these last two days has been much cooler in the mornings (maybe between 50-60 degrees F) and that is when i experienced the problems. Then after i drive it for a while i notice the lurching will go away which makes me think that it has somthing to do with the consistency of the gear oil. Have you/anyone expereienced this?

I also noticed that it seems like gear oil might be leaking from the flange that the rear driveshaft connects to on the transfercase side, (oil on the underside of the truck in that area) which concerned me to make me think that maybe this is what was causing the above problem(maybe transfercase/trans was taking a crap, but now i don't think so) but i wonder if i need to tighten the nut that holds that flange on because i have heard some people say those have come loose on them.

Thanks
