What is a power Lok differential?

The Powr-Lok differential resists wheel spin on bumpy roads and provides more pulling power when one wheel tries t.o slip. In many cases of differences in traction, pulling power willbe automatically pro· vided until both wheels start to slip. In diagnosis of vehicle operators’ complaints. both wheels slip, t.

What is Dana 44 Trac Lok?

Dana’s New Spicer® Trac-Lok™ Limited-slip Differential Improves Traction for Medium-Duty Trucks. In addition to providing automatic engagement and enhanced traction, the Trac-Lok device is lightweight and fully interchangeable with a Dana standard S140 axle differential.

How do I identify Dana differentials?

To figure out exactly what axle you have, you can look for the Dana stamped bill of materials number. This stamped number can usually be found on the righthand side or on the longer axletube on the same side of the tube as the differential cover, facing the rear of the truck.

Is a Dana 60 a limited slip differential?

The passenger car version of the Dana 60 came equipped with the Mopar “Powr-Lok” semi-float limited-slip differential option from 1966 to ’69. The Powr-Lok differential used 30-spline axles. The axle bearings, seals and retainer packages are interchangeable.

How does a Trac-Lok differential work?

Trac-Lok automatically distributes the available rear torque to the rear wheel that provides the most traction, thus helping to reduce wheel spin caused by lack of traction in the other rear wheel.

How do I identify my differential?

Without an ID tag, differentials are identified by the number of cover bolts, the distinctive shape of the cover, the number of ring gear bolts, and ring gear diameter. They can also be identified by whether the center section is an integral or dropout design.

How do you tell if you have a Dana 50 or 60?

You can also look for a sticker on the rear of the passenger side axle tube. Look for a number on the lower right of the sticker. If it’s a 229 it will be a Dana 50 and if it’s 248 it’s a Dana 60.

Which is better limited slip or locking differential?

Limited slip differentials provide your vehicle with the best traction around. Locking differentials might give you good traction too, but the traction that you will experience with limited slip differentials is better. For starters, they will make it easier to turn on roads which are slippery and wet.

Is it bad to drive with diff lock on?

First, a diff lock should not be engaged for on road driving, unless weather conditions such as snow or ice mean that extra traction is required. The diff lock will release once traction has been regained. Some automatic locking diffs will only disengage once one wheel is required to spin faster than the others.

Is a Dana 70 better than a Dana 60?

It can be identified by its straight axle tubes, 10 bolt asymmetrical cover, and a “70” cast in to the housing and is visually similar to the Dana 60. Both front and rear axle variations were first offered in 1957. The Dana 70 is generally regarded to have more strength than a Dana 60 but not as much as a Dana 80.

Is Dana 60 a ton?

One thing that’s confusing about the Dana 60 axles is that a Dana 60 in front is usually considered a 1 ton axle, and a Dana 60 in the rear is usually considered a 3/4 ton axle. This is most likely because the rear axle in a truck carries more weight than the front (when loaded).

What kind of differential does a Jaguar 4HU have?

From 1976-1985, the differential was a Salisbury 4HU Powr-Lok that came with either 3.07:1, 3.31:1 (1976-1982), or 2.88:1 (1982-1985) ratios. From 1985-1987, a 2.88:1 DANA unit was used.

Is the Powr Lok differential the same as a conventional differential?

The Powr-Lok differential has the same power flow as a conventional differential plus a more direct flow which automatically takes effect as driving conditions demand. This more direct power flow is from the differential case to each axle shaft through a clutch plate and ruse arrangement.

What kind of differential does a Jaguar XJ-S have?

The XJ-S has apparently been fitted with at least three different differentials (“final drive units” for you Brits). From 1976-1985, the differential was a Salisbury 4HU Powr-Lok that came with either 3.07:1, 3.31:1 (1976-1982), or 2.88:1 (1982-1985) ratios.

Is there a 3.54 power lock diff for a Jaguar 4HU?

The stock settings are way to strong for such a medium light weight car. Anyone got a 3.54 power lock diff going spare? It NEEDS to be ramp rate changed…BUT IMHO you would never do this today, as a Gripper unit is the way to go. By Gripper do you mean a LSD like Quaife? That would of course be the best, but hidiously expensive? Yes.
