Are you experiencing any steering problems?
It could mean there’s an issue with your vehicle’s rack and pinion. This component is connected to the steering knuckles, which turn the steering wheel left or right.
We installed a new one on a Honda Odyssey. Our technician determined that it needed to be replaced when he noticed it was leaking.
This is a good reason why you should have the rack and pinion inspected.
Rack and pinion replacement
Installing a new rack and pinion
To replace this part, the technician needed to remove a bracket for the engine mount.
This one was relatively simple to install. For vehicles that have switches and multiple sensors, the process can be more complicated.
A stiffer steering wheel is one sign of a bad rack and pinion. This problem can be caused by leaking steering fluid that’s getting bound up, or the system being low on fluid.
You can help protect this component through regular power steering fluid exchanges.
Signs of a bad rack and pinion
Rack and pinion problems are normally noticed when the vehicle is in a shop.
The only way a driver would notice a leaking rack and pinion is if they see spots of power steering fluid on the ground. This part is so buried that a lift would be needed to isolate it.
Bellows boots, which slide over the end seals of a rack and pinion on each side, will be very damp. Moisture could be seen or there may be fluid leaking out if they’re torn.
New and old rack and pinion
Leaks are also possible where the fittings screw into the rack and pinion, but those are pretty rare.
The end seals are normally what give way, because they’re always under pressure. The boots are there to protect the seals from the elements.
Other problems we look for
Dampness or leaks aren’t the only issues our technicians look for when inspecting a vehicle.
They also make sure there isn’t a lot of movement among suspension parts, such as the inner tie rod ends.
The mounting bushings – where the rack and pinion mounts to the subframe – are checked, as well. Those bushings can become worn overtime. If the rack is moving, the steering might feel a bit loose.
Problems could also arise if there is some sort of impact.
When performing an oil change on a Ford F-150, one of our technicians found that the end of the rack and pinion was broken. This damage had occurred when the vehicle drove over a pothole or hit a curb.
Water and dirt can get in if this component cracks.
Preventing unwanted problems
For some peace of mind, bring your vehicle to a place that offers good quality oil changes and digital vehicle inspections.
Minor problems may be caught early on and they can make sure your car is receiving the maintenance it needs.
Getting power steering fluid exchanges every 30,000 miles or so (depending on the manufacturer’s recommendations) is one way you can take care of your rack and pinion.
If you notice a change in how your vehicle steers or see some type of fluid near your car, have an automotive expert make sure that something isn’t going on.
