4WD drive feels tight - '98 Jimmy
just bought a 1998 jimmy with 3 button switch when I put it into 4hi it locks in and works with a whine but feels like it is being held back. You have to give it some gas pedal to move it and if on a hill and in neutral it will not roll take it out of 4hi to 2wd it is fine. Thought maybe the ABS was doing it so removed the fuse no change. I took all 4 wheels off ground in 2wd and neutral it is fine brakes work fine and release fine. In 4hi right rear wheel is tight would not move by hand. In drive the 3 other wheels move fine but right rear moves a lot less and seems to struggle. Tied off the brake caliper so it wouldn't be a factor but did not help. Does the right rear not drive in 2wd?
