How much does it cost to fix limited-slip differential?
Depending on the make and model of your car, as well as its condition, expect to spend between $1,500 to $4,000.
Do Ford Rangers have limited slip diff?
Limited slip differentials are not common in Ford Rangers; however, some do have them. The limited slip differential will transfer power from one wheel to the other if one of the wheels begins to slip, thus providing the Ranger with better traction on slippery surfaces.
Should I add limited-slip additive?

Should I use a friction-modifier additive with AMSOIL synthetic gear lube? AMSOIL synthetic gear lubes are limited-slip capable and do not typically require an additional friction-modifier additive. However, depending on the differential’s friction material and degree of clutch wear, chatter can still sometimes occur.
Can you put limited-slip oil in open differential?
Registered. our limited slip differentials require adding a friction modifier to the oil. it will work fine in an open differential.
Does Lucas synthetic gear oil have limited slip additive?
Does Lucas gear oil have limited slip additive? Lucas gear oil contains a special additive package that increases lubricity and insures less gear noise and longer bearing life. Designed to stand up to high temperatures without losing its lubricity. Excellent for use in limited slip differentials.
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.
How much is a rear diff rebuild?
If new gears are needed the price can be at least $1,500. Going to the worst-case scenario, if the differential is beyond repair, you’ll need the component to be replaced altogether. You can expect a rear differential replacement to cost up to $4,000.
