Wanted Diagnosis/repair advice

[WOLFYBOB]

Greetings,
I have a 2004 Ford Explorer 4x4 4.0. I have had multiple problems with this vehicle, but have managed to overcome until now. My latest headache is a result of my own stupidity. I got a flat, replaced it with the spare, but did not stop to tighten the lugs soon enough. This resulted in several lugs backing off and snapping 4 studs. Luckily I did not cause an accident and was able to get towed home. Due to other circumstances, the vehicle has been parked for over 6 months through the winter. I recently got back to it and have replaced the hub with a repair kit ( hub with studs) and new bearing. I put everything back together today. I forgot to mention, it was the left rear wheel this happened to. Now, the vehicle is stuck in 4x4 LOW and only the right rear wheel appears too be getting any drive. I have the rear end jacked up on both sides, the right side turns at idle. The left rear turns only when accelerated. Obviously I have moreproblems than broken studs. What do I try or look at first? Any suggestions would be appreciated.

you need to have the truck off of the ground in order to fix this problem. if your explorer has advance track and auto 4wd the issue its having is a sensing issue. i had a similar problem before on another vehicle with traction assist. the advance track and auto 4wd are sensing slippage, to reset this the vehicle needs to be lifted and allowed to drive a few tire rotations. after that put it on the ground and see if anything changed.
