What causes the differential noise in Hyundai Santa Fe?
1 Answers
There are several reasons for differential noise in Hyundai Santa Fe: 1. Insufficient lubricating oil, whether the specified hypoid gear oil is used; improper adjustment of the main and driven gears, resulting in poor gear meshing and noise. 2. Wear of the main and driven gears, or looseness of the main gear bearings, which fails to effectively constrain the main gear; loose differential bearings, causing abnormal noise. 3. Wear of the differential planetary gears, and wear of the side gears and washers, leading to abnormal noise. The function of the differential is to meet the requirement of different wheel speeds when the car turns. The car differential enables the left and right (or front and rear) drive wheels to rotate at different speeds. The steps for replacing the car differential oil are as follows: 1. First, lift the car and place a large container underneath to catch the waste oil. Use an appropriate screwdriver to remove the inner and outer casings of the transmission. 2. Remove the last oil pan, being careful to support it by hand as it still contains a large amount of waste oil. 3. Remove the oil pan gasket and clean the surrounding dirt. 4. Wipe the surface of the replacement parts clean, ensuring there are no water or oil stains, as these can cause oil leaks.
