slippage in rear

[Robert Thompso]

I have a 1998.5 3500 Dodge Dually Ram, 5.9 24 valve cummins engine, Spicer DANA 80 rear with 4:10 ratio..........it's slipping on initial take-off .......what's wrong and how do I correct this?

Are you saying that you are slipping the tires or the rear end is slipping? Can you describe it a little more....

 

[Darrin Tosh]

bigger tires, better tracion..I had the same problem when I installed a Cummins,.....

Travis is even more familiar with the problem,..

 

[argve]

yeah I never did ever figure out why the rear tires on the Dodge wore out so quickly compared to the IDI I had...

 

[Robert Thompso]

It's the rear slipping not the tires.........sort of a shudder

 

[Goofyexponent]

side gears worn out?

 

[NCheek]

Has it been lifted? Possibly an improper driveline angle causing a "bind" in the ujoints?

I agree check your u-joints. Also does it have limited slip? If so you could try adding some limited slip additive, I do believe the factory calls for some. I would change out the fluid if you add the additive - what's a better time.
