I posted here because the front diff is a stock component, however, the transfer case differentials sub forum might be a better place for this discussion.
Included is a video showing what has to be excessive front diff movement.
Why?
Since I first noticed the issue I have tried a different front diff, new cv axles and even swapped original cv axles back into the 2nd diff. While it is entirely possible I got a 2nd diff with the same issue, I still want to run it by the board.
Recently I removed the front drive shaft to service it thinking the slip yoke might be dry. I removed the front u joint caps to grease them, and did see some wear on the cross from the u joint pin rollers, it felt "snaggy" but freed up with new grease. In the video the front joint looks ok. Could it be grabbing the diff and throwing it like this?
Another "might mention this" thing I might mention-the little clips holding both the half shaft on passenger side and cv shaft on the driver side are not there, from the removal-re installation. What do those clips really do besides make it harder to remove the shafts?
Driving in 2wd is fine as far as I can tell. The only time this happens is under load in 4wd -and sharp cornering in 4wd.
I should have shot a video of backing out of the driveway right after this. In 4wd mode, wheels cut hard right backing up very slowly it really jumped hard.
Pretend you are hanging upside down under the truck. Look at the diff--0:47 and 0:59 it really bounces good. It almost looks like it is broken from the mount.
