What Causes the BMW X6 to Jerk When Turning the Steering Wheel While Stationary?
2 Answers
The reasons for the BMW X6 jerking when turning the steering wheel while stationary include loose steering gear bearings or excessive clearance in the steering gear meshing transmission pair. Below are the specific causes and solutions: Specific Causes: Wear and looseness of the main and tie rod ball studs, causing play; severe wear of the steering knuckle kingpin and bushing, resulting in excessive clearance; looseness of the front wheel hub bearings; bent front wheels or loose rivets; deformation of the frame and wheel rim; excessive toe-in. Solutions: Clean the throttle body; inspect or replace the spark plugs; check for air leaks; perform a computer scan to check for fault codes. Inspect oil pressure and replace components if necessary; clean the fuel system and check the idle speed motor for carbon buildup, which should be cleaned if present.
I have a BMW X6, and it used to jerk violently when turning the steering wheel while stationary, as if there was a stone causing trouble. After consulting a mechanic, it was found that the issue was caused by pressure fluctuations due to aging or pressure leakage in the hydraulic power steering pump. Friction between the tires and the ground can also exacerbate the jerking, especially in uneven parking lots. When the steering linkage ball joints wear out, it creates a sense of looseness, which becomes more noticeable when turning the wheel forcefully. Additionally, dirty or insufficient power steering fluid can make the system unstable. I recommend regularly changing the power steering fluid and inspecting the steering components, rather than waiting for the problem to worsen. I remember one time I neglected it, and the pump burned out, costing a fortune to repair. For safety, check the tire pressure and power steering fluid level as soon as you notice any jerking.
