Trying to figure this issue out... had some bad vibrations that started getting worse.
Last week or so, got under the truck and rotated the driveshaft at the rear pinion by hand. It seemed to have excessive slop and it seemed to turn a lot more than what should be allowed with 010 backlash.
I figured I screwed something up again when I installed the 4.56 gears, and backlash was way off.
Well tore it apart... without the axles in, everything felt good. I do think the inner pinion bearing was bad, or going bad; at the very least, when I smacked the pinion out the bearing cage was loose enough that half the roller bearings.
So got new bearing installed properly this time, everything is good. Replaced both pinion bearings and races. Checked backlash at 3 spots, and it's at .010 which is within spec. Pinion bearing preload is around 22-23 in-lbs. Gear pattern looks good.
Slid the axles in, but didn't c-clip, and sat the tires on to get some weight.
Best video I could get. Is that anything to be concerned with? It appears that there may be some slop between the 2 sets of spider gears. But maybe that's normal and I'm just paranoid.
Can the (most likely, as they are OEM) toasted LSD clutch packs cause any of these issues?
