What are the symptoms of a faulty car differential?
1 Answers
Common differential failures are as follows: 1. Abnormal noises during driving, such as a "clanging" sound from the rear axle (differential housing), which may disappear when shifting to neutral. 2. A roaring sound similar to an airplane during driving, especially severe within one or two seconds after releasing the throttle, often caused by wear of the main and driven gears. 3. Excessive gap (slippage) between the half-shaft gear (spline) and the internal hole gear (joint) of the differential due to excessive wear or improper oil selection. 4. Improper fit of the cross-shaft differential housing, or cross-shaft detachment or breakage. 5. Improper meshing between the half-shaft gear and the internal planetary gear of the differential, such as excessive gap or slippage. 6. Internal friction plate burnout or slippage.
