Power steering fluid does not leak out of the input shaft because of the power steering input shaft seal. On the input shaft, there are two seals: one is a dust seal, and the other keeps liquid from leaking. Both are subject to wear and tear over time as they are exposed to high heat and used on a regular basis.
Your power steering system must be connected to the steering shaft in order to work. This runs down from the steering wheel and gives the power steering system driver input. The steering shaft links with the power steering system at the gearbox, and two seals guarantee that no dust enters and that the power steering fluid is preserved.
What is the Use of a Power Steering Input Shaft Seal?
Since the power steering system is hydraulic in most modern cars, seals are utilized to avoid fluid from seeping out and debris from entering the mechanical parts that drive the power steering system. Hydraulic fluid can leak from the power steering input shaft when the seal on the input shaft is compromised, causing the system to overheat or break down completely. This is the function of the power steering input shaft seal, and it’s why it’s so critical to the power steering system’s overall operation.
All seals will eventually need to be replaced due to wear and tear. The quantity of use and the age of the system are the two most important criteria in deciding how long the seal will endure. Your power steering input shaft seal may be leaking if you observe excessive power steering noise or a fluid leak.

What are the Symptoms of Power Steering Input Shaft Seal Failure?
Watch for the following symptoms to make sure the power steering input shaft seal needs replacing:
- Low power steering fluid
- Difficulty steering
- Power steering fluid leakage
- Whining noises when turning the wheel
How is Power Steering Input Shaft Seal Replacement Done?
- The engine is started, and the power steering system is tested. The lower yoke connecting the steering column to the rack and pinion input shaft is disconnected.
- The damaged input shaft seal is removed, and the shaft is cleaned and inspected.
- The bottom yoke is reconnected, and a new input seal is inserted.
- The air in the power steering system is purged and replaced.
Your system will lose fluid if the power steering input shaft seal fails. The power steering pump and other components may suffer as a result. If you suspect a problem, have your system evaluated and fixed by one of Swezo’s skilled mechanics. Contact us today!
