What causes steering wheel vibration in BMW X5?

[DiWeston]

Steering wheel vibration in BMW X5 is caused by damage to the clutch inside the transfer case. Reasons for internal transfer case damage: Overloading, overweight, and insufficient gear oil leading to high-temperature wear. Reasons for clutch damage: Keeping the foot on the clutch pedal for extended periods while driving, causing clutch slippage, clutch disc burning, and in severe cases, burning and scoring of the clutch pressure plate and flywheel surface, leading to issues like clutch pressure spring annealing. Other factors include overheating due to excessive working temperatures, lack of lubrication leading to wear, insufficient free travel or excessive load cycles, improper adjustment of the release lever, and poor condition of the release bearing return spring, all of which significantly impact clutch release bearing damage. Incomplete clutch engagement results in sliding friction, wearing out the clutch and potentially burning it.
