Rear pinion question
Hello all. Had the Burb out last night and noticed another strange noise to add to the list. Checked under the truck, and the rear yoke at the rear axle is moving around quite a bit. The u joint looks ok, it's the yoke assy. that's moving. The pinion shaft stays still and the yoke moves up and down when I push up on the driveshaft. I looked in the Haynes manual, but all it said was to mark the location and count the exposed threads on the pinion nut for use upon reinstalllation. This was info to replace the seal. Anyone know how this thing goes together, what the torque spec should be, etc? Is it possible that the pinion nut just loosened up, or is something really fubar'd? Thanks for any help guys, I'd really appreciate your input before I go and rip everything down. BTW, the truck in question is a 87 V1500 Sub w/3.73 ratio.
