2001 rt dakota standard cab. I have noticed a single pop two seperate times while first backing up. If you lay on the gas from a stop it will only lay one black mark and it will only get to 70mph up a ramp floored. If the clutches are bad the truck cant be putting all of its power to the ground. any thoughts or ideas? thanks

 

Could be a u joint causing the POP - Do you have an LSD?

 

its supposed to have an lsd

 

Pop the Diff cover drain the old oil look at it see if something looks wrong chipped broken if good re-cover re oil at least you know.

oil cover gasket + oil $30 to $40

Check all U-joints

Check rear end everything loose bolts clamps shocks shock bolts leaf spring clamps bolts so on.

Check spare tire mount.

Check transmission mounts and bolts/nuts.

 

Check diff gears

 

As long as one wheel isn't spinning, it is putting all the power to the ground, worn clutches won't stop the differential from working as an open.

If a tire slips, then yes, you are losing power (traction).

I'd check u-joints, tranny and motor mounts.
