This morning as I pulled off the highway onto my street I heard a banging noise coming from the rear of the truck
When I pulled into my driveway I noticed that one rear wheel would slide and jump rather than freewheel. I'm wondering if for some reason the axles are locked together. I hope this makes sense as I don't know much about how the rear end works.
After the truck set all day I drove a short distance and now everything seems to be normal. Any ideas about what might be going on would be greatly appreciated.

 

Got a build sheet for your truck? See if you have the limited slip rear..... they are know for tossing parts.....

Probably wouldn't be a bad idea to pull the cover, and take a look..... if nothing else, clean it out good, and feed it some fresh fluid.

 

Thanks man. That"s on my to do list for first thing in the morning.

 

either your spider gears have broken and lodged a piece of the gear,
or
an LSD retainer clip thing has fallen out and lodged into the spider gear.

i would remove the diff cover, clean everything and inspect it. the retainer clip is sort of normal and the diff could still run another 100K miles. but a broken spider should be replaced.

DIY for diff service.
