"skipping" in driveline 2wd up a steep hill
 

Just got back from a trip to TN and after a 6 hour drive there, trying to drive up a very steep paved driveway the driveline made a skipping motion the whole way up. No change in rpm, no slip in the trans at all. Felt like a chain skipping on a bike. Drove 6 hours back home with no issues. Serviced the rear end and fluid was good with no issues found. My next guess is a transfer case issue or a sun gear issue in the transmission. Anybody ever dealt with a similar issue on a steep incline? Also have a minor delay from off throttle accelerating til the truck starts moving, leading me more to the transfer case. Any guidance before I tear it apart would be a help. Thanks in advance.

Can you replicate it by powerbraking?

that what my dana 70 did when i had broken pinion teeth

Unable to recreate through power braking the truck. Pulled the rear end apart and looked at the factory gear locker. From what I cam see no signs or issues found in the rear. Replaced the fluid while I was there. Was able to get a similar skipping feel when in 4lo on wet grass. Going to drain. The transfer case next and look at the fluid.
