What Causes the Abnormal Noise When a Corolla Goes Over Speed Bumps?

[McKiara]

Corolla making abnormal noise when going over speed bumps may be due to component aging, excessive tie rod clearance, dust cover rupture and oil leakage, or chassis issues. Component Aging: If the ball joint of the stabilizer link is aged, you can remove the tire to check if the rubber at the ball joint has aged. Excessive Tie Rod Clearance: Check if the tie rod end has excessive clearance. This requires professional judgment, but you can shake both sides of the tire forcefully when the vehicle is lifted to see if there is any looseness. Dust Cover Rupture and Oil Leakage: If the dust cover of the drive shaft is ruptured and leaking oil, it will accelerate the wear of the drive shaft, leading to abnormal noise when damaged. Chassis Issues: Damaged or loose chassis components can also cause abnormal noise when driving on uneven roads. Generally, it is necessary to check some steering mechanism screws and shock absorber rubbers.
