What is a cracked rear differential?
Cracked rear diff covers is quite common and caused by numpties over tightening the hex bungs in the alloy cover plate. A replacement cover plate is easy to pick up. Just drain the oil if there is any in there, replace the cover and torque it up evenly and then refill with oil to the level of the oil fill bung.
How to tell if you have a bad differential?
Typically, there are two symptoms you’ll notice when you have a bad differential, or car differential problems: Rear Differential Noise – if you hear howling from the rear of your truck or SUV when you’re driving, it’s possible it’s rear differential noise.
What does it mean when your rear differential is leaking?
Rear differential leaks are the culprit, either at the axle seals, the pinion seal (where the driveshaft attaches), or the rear differential cover. Light brown or grayish fluid on the ground under the back of your truck is an indication that you have a differential fluid leak.
Why is my rear differential making so much noise?
Many times, rear differential noise is mistakenly thought to be tire noise and ignored, leading to more expensive repairs. Rear Differential Leak – more commonly, the problems stem from low rear differential oil.
When do you need to replace the rear differential?
Replacing the rear differential gears. When teeth on the gears have chipped or worn badly, they must be replaced to eliminate the noise and potential for failure. These ‘hard parts’ are the costliest components, and repairs can only get one step worse. Complete rear differential replacement.

What’s the difference between front and rear differential noise?
Only difference between a wheel bearing noise and a rear differential noise would be the fact that the wheel bearing noise will change with wheel speed but usually will not change with load variations (accelerations/decelerations) while the noise from a rear differential will change with wheel speed and load.
How much does it cost to repair a bad front differential?
If you catch it early, the fix could be as simple as a gear oil change. The average cost of repairing bad front differentials and rear differentials will depend on the severity of their condition. Generally speaking, it should not cost more than $400 to repair most rear or front differentials.
