Q: My 2015 BMW GT535 has a cumulative mileage of 87,000 km. The chassis makes abnormal noise when turning and when braking. After checking at the 4S shop, the repair plan given was: replace the left and right upper arms, with a total repair cost of more than 11,000 yuan. Do I have to replace these parts?
A: The right upper arm bending arm bushing of this car often leaks oil. In addition, the excessive clearance of the bending arm does easily cause abnormal noise when the vehicle brakes. However, you can choose to replace the left and right upper arm straight arms and bending arm bushings, and do not replace the assembly. The estimated repair cost is about 2,200 yuan, and the repair quality can be guaranteed.
