Water getting into the steering rack can cause rust and wear—but how do you spot it early? Here are the key ways to judge.
1. Check the Rubber Boots
The rack’s rubber boots (bellows) keep water out:
- Look for cracks, tears, or splits on the boots. Even small gaps let water seep in.
-
If boots are loose or detached from the rack, water can easily enter the internal parts.
2. Look for Rust or Moisture
Inspect the rack itself for water signs:
- Check the rack’s metal parts (especially the inner rod) for rust spots or a dull, damp finish.
-
Wipe the rack with a cloth—if you see water stains or dampness (not just oil), it may have water inside.
3. Notice Steering Feel Changes
Water damage affects how the steering works:
- Stiff or notchy steering: Rust makes parts grind, so turning feels rough or stuck.
-
Unusual resistance: Steering needs more force than usual, especially at low speeds.
4. Listen for Strange Noises
Water can cause new sounds when turning:
- Grinding or squeaking: Rusty parts rubbing together make these noises.
-
Clicking when turning: Water may have damaged seals, leading to loose parts that click.
5. Check for Fluid Issues (Hydraulic Racks)
For hydraulic steering systems:
- Look at the power steering fluid—if it’s cloudy (not clear/amber) or has water droplets, water has mixed in.
- Fluid leaks around the rack: Water can damage seals, causing leaks alongside moisture.
