How does power steering affect a rack and pinion system?
The power steering makes it easier to steer, but adds complexity to the compact rack and pinion system, which can make it more difficult (and expensive) to repair. Adding power steering to a rack and pinion steering system changes the design slightly. A cylinder with a piston is put in the rack, and fluid is added to both sides of the piston.
Do you need to replace rack and pinion?
Most rack and pinion leaks will require the replacement of the entire rack and pinion assembly even if most of it works just fine. The good news is you do have another alternative to an expensive replacement.
What causes a leak in the rack and pinion system?
There are three main factors that can cause leaks: The seals between the steering column and the rack and pinion or around the tie rod connections can shrink, crack, dry out or become unseated. It’s worth mentioning that the leak is coming from your power steering system, not your rack and pinion system.
