Broken Differential?

I am not a mechanic, but from what you describe, I would say one of the axle shafts is broken. I had a co-worker from Jamaica. In his country, truckers take the axles in the house with them every night.

 

wat do u mean take the half shafts inside at nite? pull the axles first then u will know wat is wat

 

See, I am not a mechanic. From what he described, one of the axle shafts could be broken. Due to the terrain and the way equipment is abused in Jamaica, axle shafts are frequently broken and they are a hot item for midnight auto supply.

 

well yeah they can get broken due as the hills we have and some outrageous weights we haul out here, since day i hauled 120,000lbs net on 18 wheels on the sterling u see on my pfofile

 

Pull the rear Differential. if the short shaft between the rearends is turning and the truck is not moveing, their is a problem in the back rearend.

 

almost definetly an axle if its not making any horrible sounds. put the truck up on jacks and spin the tires, either part of the drivetrain or another tire will spin. if it doesn't, thats where your problem should be.

and remember to change the diff oil too!

 

sounds like spicer na400
