2009 Mule trans 4x4

[Glock_King]

I bought a used 4010 and have had it a couple months now with no issues or problems. Recently I have used it to pull a stalled vehicle about 30 feet and pull out a stuck vehicle. Both times I put it in 4wd and locked differentials. After each occasion while driving the unit it feels as though the park brake is engaged and is very sluggish and loss of power. I have double checked the diff and 4wd as well as engage and disengage the brake in case it was dragging or slightly engaged, everything seems dime there. Any ideas why it would do this or what is causing it ? Any help would be greatly appreciated

Ive noticeed that even when I come to a full stop and disengage everything, the 4x4 sometimes doesnt disengage and makes it feel like it is dragging down. I usually put it in reverse and then back into hi a time or two and it goes back to normal.

Mine has always done this since it was new. It's normal, but I've also learned to use the reverse for a couple of feet, when shifting back to 2wd.The owners manual says it'll shift back to 2wd on the fly, and it does, only with a huge thunk! Making the kind of noise, and feel that you just know, can't be good.

_{after disengaging the 4x4. stop and back up some. this will take the pressure or torque off the diff so it unlocks. They all do this.}
