What does Ford call their limited slip differential?

What does Ford call their limited slip differential?

Ford’s limited-slip differential is called traction-loc (though the spelling has changed over the years). Trac-loc differentials use a mechanical clutch system to lock the wheels when necessary. The Torsen is a worm-gear limited-slip differential.

Do limited slip differentials wear out?

Maintenance. A limited-slip differential typically requires more maintenance than an open system as there are clutch plates that can wear out and oil that may need to be changed.

What happens if you don’t add limited slip additive?

What happens if you don’t use limited slip additive? Friction modifier makes the fluid “slicker” so without the additive the limited slip clutches will grab and it will shudder going around tight turns. And yes, eventually it will destroy the clutches and render the limited slip useless.

What is Ford Positraction called?

“Posi-Traction” is simply a GM name for their limited slip differential. Ford’s name is Traction-Loc. (Chrysler’s name if I remember correctly is “True-grip”). It’s very common for people to believe they have a “posi” etc if they can spin both the wheels, when in fact it just means both tires have poor traction.

Does Ford F150 have limited-slip differential?

Ford F150 Limited Slip A Limited-Slip Differential works much the same as an open diff; it is intended to keep the wheels moving equally at different vehicle speeds. But the variance arrives during low traction situations.

What happens when a limited slip differential wears out?

Limited slip differentials tend to lose their slip-limiting qualities when they wear out. Once the fluid wears out, the differential will progressively fail to transfer power while cruising or turning.

What does a bad limited slip differential sound like?

Clunking and banging noises on the corners can be due to lack of sufficient posi-traction lubrication, broken spider gears, or worn posi-traction or limited-slip clutches. This rear differential noise is described as a heavy clicking type of sound which occurs every eight feet or so.

How long does a limited slip last?

Most regularly driven rigs should need the rear differential rebuilt after reaching 100,000 miles. Those that see a mixture of sand, dirt, gravel, and snow or are used for towing or off-pavement duties will probably need the limited-slip rebuilt before 60,000 miles.

What happens when a limited-slip differential fails?

Limited Slip Symptoms Limited slip differentials tend to lose their slip-limiting qualities when they wear out. A traditional clutch-type differential will lose its ability to transfer power to the slower spinning wheel, essentially turning it back into a standard “open” differential.

What does the limited slip additive do?

Kendall® Limited-Slip Axle Additive Concentrate is a special additive used to modify the frictional characteristics of axle lubricants for use in limited-slip differentials. It helps to eliminate chatter in limited-slip differentials when added to non-limited-slip API GL-5 gear lubricants.

Do you need limited slip additive with synthetic oil?

Mobil 1 Synthetic Gear Lube LS 75W-90 contains special friction modifiers designed for limited slip-type differentials. In most applications, the addition of special LS (limited slip) additives is not required.

How does a limited slip differential work on a car?

Limited slip differentials lock two wheels together while traveling in a straight line. While cornering it allows for the outside wheel to rotate faster than the inside by overcoming the tension of its clutch. A clutch type differential is the most common, consisting of two sets of multiple disc clutch packs located on each of the two side gears.

How can I tell if I have a differential or driveline problem?

Driveline, Axle, Ring and Pinion Gear and Differential Noises and problems can sometimes be tricky. Noises, vibrations and other irregular driving characteristics can often help diagnose a differential or driveline problem.

How does a limited slip rear tire work?

A limited slip rear uses a special additive to the gear oil when you do a gear-oil change, and it is necessary or damage could occur. An open differential (like the one in the video) does not use the special additive and the tires spin in opposite directions when one tire is spun.
