Positraction And Limited Slip Differential

Traction-Lock (Also referred to as a Track-Lock, not to be mistaken with the Dana Spicer Trac-Lok) This is the second design limited slip that Ford used in both the 8-" and 9" rearend designs. It is a fairly good design for moderate horsepower applications. This is a clutch type design that uses four plain steel clutches, four fiber lined clutches, and one plate that is steel on one side and has fiber lining on the other side. It uses a two-piece case that looks very similar to the standard open carriers, except the parting line between the two case halves is covered by the left half that "wraps around" the right half. The parting line between the two halves on a standard case is easy to see and is not covered. Traction-Locks are not very aggressive and tend to wear out fairly quickly if used heavily.

Newer design Ford rearends such as the 7.5", 8.8 ", 9.75", 10.25", and 10.5" also can be ordered with Traction-Locks. These differentials use a one-piece case with two spider pinion gears, except for the heavy-duty 10.5 " rearend, which uses three spider pinion gears. The 7.5 " and 8.8" designs have soft clutches that tend to wear- out quickly and are not aggressive even when new. The 10.25 " unit uses composite clutches that holdup fairly well, but it is not aggressive and tends to slip too much when needed off-road. Trac-Lok is a medium-duty limited slip and will hold up without breaking, but will wear out the clutches quickly under heavy-duty use. If the unit wears out it usually can be rebuilt. (factory)


BRAKE REPAIR & SYMPTOMS

Brake pads and brake rotors are wear items and should be inspected regularly and replaced when approximately 1/8" of friction material is left on the brake pad backing plate. Brake rotors should be replaced when at or near the discard thickness engraved on the brake rotor.

CLUTCH REPAIR & SYMPTOMS

A complete clutch repair is diagnosing the cause of the problem and replacing all worn or damaged clutch components. Clutch component parts do wear and some self adjust to compensate for normal wear in clutch disc friction material.

TRANSMISSION REPAIR, SERVICE & SYMPTOMS

Neglect and overheating causes 90% of all transmission & transaxle failures per industry feedback and most of them are due to worn out transmission fluid. Regular transmission service can help avoid major transmission repairs

DIFFERENTIAL REPAIR, SERVICE

High operating temperatures reduce the gear lube's ability to lubricate, which can lead to axle and bearing failure leading to major differential rpairs. Differential service includes draining &fillin with new gear lube. to avoid expensive repairs. Most manufacturers recommend differential service every 30.000 miles.
