Addressing these related issues at the same time can save on labor costs in the long run, as much of the disassembly is already done.
Seasonal Pricing Variations
While less common for major repairs like rack and pinion replacements, some repair shops might offer seasonal discounts or promotions. It’s always worth inquiring about any available specials, especially during slower periods for the automotive repair industry.
Diagnostic & Repair Process
How are steering rack issues diagnosed?
Since most power steering issues generate the same symptoms, it can be difficult to diagnose one part without checking the condition of the whole system. A technician will check for leaks, examine the belt tension and listen for problems with the power steering pump. If these all check out, and no other issues are found, the steering rack will be suspected of failure, if the symptoms dictate. Common diagnostic steps include:
* Visual Inspection: Checking for fluid leaks around the rack and pinion assembly, power steering lines, and the power steering pump.
* Power Steering Fluid Check: Assessing the fluid level and condition. Low or contaminated fluid can indicate leaks or internal damage.
* System Pressure Test: Measuring the pressure generated by the power steering pump to ensure it’s operating within specifications.
* Steering Feel Evaluation: A technician will test drive the vehicle to assess steering responsiveness, looseness, stiffness, or any unusual noises.
* Checking for Play: With the vehicle stationary and wheels straight, a mechanic will check for excessive play in the steering wheel before it translates to wheel movement.
How is a steering rack replaced?
Replacing the steering rack involves a fair amount of disassembly — fluid must be drained, hoses and electrical connectors must be removed, and the rack has to be unbolted from the car. Replacement is the opposite order of operations, followed by standard fill and bleed procedures for power steering systems. The general steps include:
- Vehicle Preparation: The vehicle is safely lifted, and relevant components like wheels and splash shields are removed.
- Fluid Drainage: Power steering fluid is drained from the system.
- Disconnection: Tie rod ends, steering column linkage, and hydraulic lines are disconnected from the old rack.
- Rack Removal: The steering rack is unbolted from the vehicle’s subframe or chassis.
- New Rack Installation: The new rack and pinion assembly is carefully installed and secured.
- Reconnection: All previously disconnected components are reattached.
- Fluid Fill and Bleed: The power steering system is refilled with the correct type of fluid, and the system is bled to remove any air pockets, ensuring proper power steering operation.
- Alignment: A professional wheel alignment is essential after replacing the rack and pinion to ensure proper steering geometry and tire wear.
Our recommendations for steering rack issues
Power steering components are subject to high pressure, high heat and high speeds. Using parts that are built to meet or exceed OEM standards will help ensure the longevity of the power steering system. Inferior parts tend to lead to repeated replacement. Always opt for reputable brands and ensure your mechanic performs a thorough inspection of the entire steering system.
Can I replace the steering rack myself?
Rack-and-pinion steering systems should be replaced by a professional technician. Many modern vehicles require removal of the front sub-frame while supporting the engine from the upper frame rails.
