2002 Jeep Grand Cherokee Power Steering System Leak Inspection Cost

Excessive noise may be noted from the power steering pump if the fluid level is low.

Power steering leaks can be evident while the vehicle is being moved, and power steering fluid may be seen on the ground. Intermittent, or failure of power steering assist may occur due to low fluid. Besides the fluid leak, the power steering pump may also begin making a screeching noise.

A vehicle can be driven with weeping or leaking power steering components. However, it will be necessary to pay close attention to the power steering fluid level to make sure there's enough fluid for the system to function. If the fluid is actively dripping or pouring out of a leak, a tow truck is recommended to prevent damage to the pump, steering gear, or loss of power steering assist while driving.

For most vehicles, the power steering system will last well over 100,000 miles before any failures occur. Mechanical failures and leaks in the power steering system are considered usually avoidable if maintenance has been performed according to the manufacturer service intervals. Keeping the power steering fluid fresh, and the system free of contaminants is the key to ensuring long power steering system life. As any system that carries high pressure will, the system will eventually fail from normal wear and tear, but this should be well into the serviceable life of the vehicle.

Since most power steering issues will generate the same symptoms, it would be difficult to diagnose only one part, without understanding the condition of the whole system. When symptoms emerge, the power steering fluid is inspected, and topped off, and the condition, and tension of the power steering pump belt is noted. The system may need to be bled of air prior to diagnosis. Any leaks will become very obvious at that time, and mechanical failure of the power steering pump will be evident from noise, or a pressure gauge inserted into the power steering line. At that time, if no other issues are found, the steering rack or steering gearbox will be suspected of failure. Any dust boots and seals will be inspected for leaks. The rack and pinion gear set will be inspected for sounds typical of mechanical failure. This systematic approach will lead a technician to a diagnosis.

Power steering leaks are corrected by replacing or rebuilding the leaking component. In some more fortunate circumstances, the power steering lines may simply become loose, and will be properly tightened to prevent leaking. In most other situations, the power steering fluid is drained, the defective component is removed, and a rebuilt or new component is installed. Once the system is reassembled, the power steering system is filled with power steering fluid, according to manufacturer specification. Finally, the system is bled of air, and the vehicle will be tested for leaks and other symptoms.

We recommend against any product that claims to stop leaks in the power steering system. These products contain sealants that will become contaminants as they cure in the power steering fluid and build up inside components that are only designed for power steering fluid. This can lead to failing power steering pumps and steering gears, and even cause additional leaks.
