97 TXT Shuttle Engine Spins but Cart won't Move

[gsmith1110]

I have a '97 TXT Shuttle. Had this same problem about 3 months ago and determined it was a spun hub. Replaced both hubs and problem was fixed, temporarily (cart ran fine for 3 months), then yesterday it stopped moving again. This time axle nuts do not spin. What is most likely cause; axle, differential, or the input shaft at the motor????
NOTE: When I did the repair I tightened the axle nuts back well, but did not have a torque wrench to confirm above 100lbs/ft torque could this be the cause?

Thanks in advance, you guys are always very helpful!!

if the nut is not spinning in the middle of the hub, i would say it's not the hub, did you check both of them, it could be , a broke axle, a bad wheel bearing and the axle slid out a little and is not in the drive gears in the rear end, could be a striped motor coupler that connects to the motor/but not likely, you have to start checking things,,, most of the time it is the brake hub, they need to be torqued to 120 - 140#

It could be you have stripped the gear on the input shaft ......

It is definently not the hub. I checked both. If I did not torque the axle nut enough what problem(s) would that most likely caused? I will start my checking there. Where is the input shaft, is that the shaft the engages the motor or the shaft the enter the differential?

Your next step would probably be to pull the differential cover and have a look inside while rotating the wheels to see what might be wrong. May be a problem with spider gears. Good luck - RAY

here's a diagram that will show you all the parts, # 12 is the input shaft,, if your sure it's not a hub,, jack the rear off the ground put on some jack stands, and grab the rear wheel and push and pull on it and see if it will move up or down and see if the wheel bearing is bad,,if not, remove the pan and look in side like bigstik40 said, if you don't see anything, then remove the motor and check the motor coupler, and the input shaft,, if you have to remove the motor, use two wrenches, one on the nut that holds the stud in the motor, and one on the nut that is holding the cable tight, DO NOT let the stud turn in the motor or you will have big problems

The correct way

Thanks guys. I guess I have my weekend plans now. I'll let you know what I find and how it turns out!

[gsmith1110]

I took the tires and hubs off both sides and the driver side axle would spin (but not with the hub on). So I dropped the differential pan and spun the axles. When the driver side (longer) axle was spun the differential turned when the passenger side was spun the differential did not turn. When the gas is depressed the differential spins, so I guess the input shaft is Okay?? Can the axle on the passenger side be broke?? When I try to wiggle the passenger axle it does have a little play, the driver side is very tight no play. Can someone please help with a diagnosis??? Thanks in advance!!!!

If you can spin the pass side axle and nothing in the rear moves I'm thinking the axle is bad or has shifted out of the side of the differential. Next step is to pull that axle. As just one more thing to try, if you can get completely under the rear on jack stands... look up and see if you can see the axle spinning when you turn it.

When I havemy son spin the pass. axle at the tire end and I look in the diff. the dif end of the pass. axle does not spin at all. Is the axle sheared in two??? How do I pull the axle. I know I probably need to remove the snap ring in front of the wheel bearing and then what?
