In the case of minor damage to the rack and pinion, the vehicle may still be able to continue to drive for a period of time, but this does not mean that it can continue to drive for a long time. Even if the symptoms are mild, continuing to drive will increase the risk.

In hydraulic steering racks, the modulus of the rack and pinion is usually selected within a certain range to balance accuracy, strength and manufacturing cost. Generally speaking, rack and pinion with a modulus between 2 and 4 mm are more common.

When the rack and pinion are loose, the driver may feel that the steering wheel is abnormally loose. When the steering wheel is turned, the response of the vehicle becomes sluggish, and even more turning angles are required to cause the wheels to move.

Generally speaking, the price of the seal itself is not high, usually between $20 and $50. However, since replacing the seal requires disassembling the steering rack, the labor cost is higher, usually between $100 and $300. Therefore, the overall cost may be between $120 and $350.

The primary function of the power steering rack is to transmit the steering force applied by the driver through the steering wheel to the wheels. This transmission process seems simple, but it actually involves complex mechanical and hydraulic conversions.

Repairing the BMW steering rack is feasible, but multiple factors need to be considered, including the severity of the problem, the damage to the rack, and the cost of the repair. For some minor problems, such as hydraulic oil leakage or minor gear wear, they can usually be solved by repair.

A hydraulic steering rack is mainly composed of a rack, pinion, hydraulic cylinder, seal, hydraulic pump, reservoir, hydraulic lines, pressure relief valve and steering torque sensor. Each component plays an indispensable role in the steering process.

Steering fluid is required for Hydraulic Power Steering (HPS) and Electronic Hydraulic Power Steering (EHPS). This is because these systems rely on hydraulic fluid to generate pressure to assist in steering operations. In Electronic Power Steering (EPS), steering fluid is not required.

1. Parts cost Usually ranges from $200 to $1,000 2. Labor cost The labor cost of ordinary repair shops is relatively low, usually between $50 and $150 per hour. The labor cost of high-end 4S shops or specialized repair shops may be higher, reaching $150 to $300 per hour. 3. Other related expenses

The hydraulic steering rack can still work through mechanical transmission without assistance. The driver turns the steering wheel, and the mechanical transmission system transmits power to the steering rack to make the wheels turn.
