What type of rear end does a single side burn out versus both tires? I've never known which was which?

Ford types?

Chevy?

I know I have a Dana 60 in my F250 but I really don't know what that means regarding type of differential.

 

All open differentials will do single-side burnouts if you overload the tire with the least traction. It's usually the right side, if both your tires are on the same flat surface because of the way the drive shaft tries to turn the rear axle.

If you have a limited slip differential, and both tires are again on the same flat surface, then if you can deliver enough torque, you can burn out both tires. In this case, due to the difference in torque applied to each tire, the rearend will tend to swing out to the left.

 

So what is a Dana 60? Open or limited slip?

I guess my 66 Chevelle I had back in the 80's had a limited slip. We called it Posi-traction back in the day.

 

It could be both, because Limited Slip was an option.

Posi or Posi-Traction are GM terms.

1959 thru today:

If the AXLE code stamped on the Rating Plate (1959/60), on the Warranty Plate (1961/79) or printed on the Certification Label (1980 thru today) begins with a letter: Limited Slip.

If the AXLE code begins with a number: No Limited Slip.

Thanks Bill. So what is a typical DANA 60?

 

Most open, some limited slip, a few lockers.

Dana 60s were in everyone's trucks, and also in hemi powered Mopar stuff. They can be anything.

 

What are lockers?

 

Detroit lockers use gears that face each other to literally lock the two axles together. These gears are spring loaded, so in a turn, the interference forces that build up from the outside axle turning more than the inside override the spring pressure and force the gears apart temporarily, allowing very abrupt differentiation. They're the most effective mechanism for tying the two axles together, short of a spool, but they're also the harshest in operation.
