Rack and Pinion leaks can be frustrating to deal with and hard to understand why mechanics charge so much money to fix them. Rack and Pinion steering systems are often used in sports cars and other vehicles that are low to the ground or have limited space in the front of the vehicle. Rack and pinion steering systems are used more in these situations because they are relatively compact systems and do not require elaborate linkages like the steering gear systems found in most trucks.
The rack and pinion is used to transfer the rotary motion of turning your steering wheel into the linear motion your tie rod uses to push your steering knuckle in and out which causes your front wheels to turn your vehicle. It accomplishes this task and gets its name by using both a rack and a pinion. The pinion is simply a small gear at the end of your steering column that rotates as you turn your steering wheel. The rack is a flat gear the pinion rests on, and as the pinion rotates its teeth mesh with the teeth on the rack which are pushed left or right creating the linear motion needed to turn the front wheels of your vehicle. To get a better idea of what a rack and pinion looks like, check out this article on how rack and pinions work.
The power steering system in your vehicle uses the power steering pump to pressurize power steering fluid and send it down to your rack and pinion. This high pressure fluids is used to help the steering rack move as you turn the steering wheel so it isn’t so difficult for you to turn your wheels when your vehicle is moving slowly or stopped. Like any high pressure hydraulic system, the power steering system used with your rack and pinion can be prone to leaks.
It is possible that one of the hoses or lines in your power steering system can begin to leak either at the connection or due to the flexible rubber section cracking. However it is more likely that your power steering system will develop a leak at one of the seals on your rack and pinion. There is a seal where your steering column enters the rack and pinion assembly, then a seal where each tie rod attaches. Each of these seals have to keep high pressure power steering fluid contained while allowing the steering column to rotate and the tie rods to move as well. Over time these seals can dry out, shrink, crack or become unseated causing a leak.
To find your rack and pinion leak you can check these three seals relatively easily. The only difficult part is fitting underneath your vehicle but if you have ramps or a jack and jack stands that can be easily accomplished, just make sure your vehicle is secure before you crawl under! The rack and pinion should be one of the lowest components on your vehicle and will likely be just under your engine’s oil pan.
The reason rack and pinion leaks are so expensive to fix is that the seals are often not serviceable, even by a mechanic. Most rack and pinion leaks will require the replacement of the entire rack and pinion assembly even if most of it works just fine.
