| Do I have a rear axle problem?
Building the kit. After finishing the two axles I noticed that I can grab the wheel hex hub and spin them freely in either direction for the front axle. Nice and smooth. But for the rear axle I can only do it spinning as if it was going backwards. Spinning the hex hub in the forward direction jams the gear inside the diff, preventing further rotation. However I can take the input shaft of the rear axle and spin it freely in either direction. I find it strange that the rear axle doesn't behave like the front axle. Is this an issue? |

probably. id disassemble and check to see if everything is correct and the correct bolts are used. Are you using the printed instructions or the downloaded ones? I built my kit from the downloaded ones even though the version number matched the printed manual that came with the kit.

I'll take it a part and see. Luckily the axle has not been installed yet. | |

Probably nothing wrong. Attach the center shafts and try again. The center shafts act as a spacer and keep the input gear from getting "pulled into" the ring gear and binding. Not sure why one axle does it and the other doesn't, but it's a common question that comes up with hypoid gears. |

Also make sure that the 4 “3rd member” screws are not overly tight, just snug. Sent from my iPhone using Tapatalk |

Right now I only have two axles built so can't attach the center shaft to the drive shaft. Instead, I took a small string and tied something lightweight to the center shaft. I used the tire wrench that came with the kit. Even with that light weight, I had it hanging off the shaft (pointing down) like a Christmas ornament. Low and behold, smooooth as butta' when turn in either direction via the hex hub! No locking. No jamming. Glad I tested this theory out before I went disassembling everything. What is the "3rd member" screws? The four screws that hold the diff or pumpkin cover on to the axle? If so, I only have those snug. The four portal cover screws are also snug. | |
