Why is my Kia Sorento's rear differential leaking?
00:04 Problems with a Kia Sorento Prime
• The car arrived with all-wheel drive problems: the rear differential was jamming and making noise.
• Metal shavings were found in the oil, indicating the need to disassemble the rear differential.
00:26 Causes of failure
• After disassembling the differential, it was discovered that the final drive was in poor condition.
• This issue is not a manufacturing defect, but is related to the powerful diesel engine, which generates high torque.
• One awkward movement can cause the differential to fail.
01:16 Problems with another Sorento Prime
• Another Sorento Prime with a gasoline engine arrived the same day, but it had a leaking rear differential.
• The final drive was in good condition, but the nut on the tailpiece had come loose, resulting in loss of all-wheel drive. • The problem was solved by replacing the nut, locking the threads, and replacing the consumables.
02:00 Conclusion
• The all-wheel drive on these vehicles is very delicate and requires careful operation.
• They are suitable for city driving and uncleaned roads, but not for driving in mud.
• Different vehicles are needed for such conditions.
