jeepjack54 Posted November 20, 2014 Posted November 20, 2014 Hello. I'm new to the forum. I have driven a Cherokee till recently when I cracked the frame so I just bought a 1991 Jeep Comanche, 4.0L 5 speed. Went to push it out of my garage today and I wasn't able to roll it forward. It will roll backwards no problem. Does anyone know why this is? There is also a suspicious transmission or hub whine, not sure if this correlates to the problem. Let me know what ya'll think. Thanks, Jack
87MJTIM Posted November 20, 2014 Posted November 20, 2014 How long has it been sitting? If trans is in neutral, then look at brakes. Jack up each end, one at a time, and try turning the wheels. If they won't turn, then you have isolated the problem. Is it 4wd? If so, shift tcase to neutral and try the same steps.
gogmorgo Posted November 21, 2014 Posted November 21, 2014 Putting the t-case in neutral may disconnect the axles from the transmission, but the drievshafts are still locked together. You likely won't be able to spin your wheels without all four off the ground.
FrankTheDog Posted November 21, 2014 Posted November 21, 2014 Neutral will not connect front and rear. It's only connected in 4 hi and 4 low. The driveshafts will spin indepentantly.
Blue XJ Posted November 23, 2014 Posted November 23, 2014 Neutral will not connect front and rear. It's only connected in 4 hi and 4 low. The driveshafts will spin indepentantly. The case in mine is a 90, it locks the front and rear together in neutral.
Eagle Posted November 24, 2014 Posted November 24, 2014 BlueXJ is correct. The early 231 transfer cases did not have a true neutral. "Neutral" disconnected the transfer case from the engine and transmission, but left the two driveshafts locked together. I don't remember what year they changed to a real neutral. Suggestion: Remove the driveshafts and then try pushing it. If it still rolls backward but not forward, your problem is in the brakes. My guess would be a dragging parking brake in the rear -- the drum brakes are designed to work better in the forward direction, and it's very common to see a parking brake that holds when the nose is pointed downhil but won't hold when the tail is pointed downhill.
