SureTrack Community Fix: Stop Your Whining

Real Fixes from the SureTrackĀ® expert information resource are documented issues from actual shop repair orders and community discussions. Read on to see how SureTrack can help you correct issues that are not easily diagnosed using OEM information alone. SureTrack is currently available free with the purchase of a current Snap-onĀ® diagnostic software version.

Whining customers are one thing you might not be able to fix but a whining power steering system should be easy. SureTrack community member jacksonwhidbey had an Acura MDX in their shop that had a whining power steering pump. They replaced the pump but that didn’t fix it. They posed the question to the community, and with the help of fellow community member todawg and others, they were able to resolve the issue quickly.

The following Community Fix summarizes the interaction between members of the community that led to the solution.

2002 Acura MDX 3.5L

Power steering whines, replaced reservoir hose.

Customer complains that power steering whines.

Diagnostic Steps Performed/Parts Replaced
Checked vehicle and confirmed that power steering is whining. Checked fluid level and it is not low. No leaks found in system. Replaced power steering pump with aftermarket unit but still whines. Signs of bubbles in reservoir.

Best Answer from Community Member todawg
Replace the line from the reservoir to the pump. If they get hard they won’t leak fluid but the will suck air. Very common problem on Honda’s.

Line from reservoir to pump sucking air.

Replaced line from reservoir to pump, ran until air in fluid disipated. No more whining noise in steering.

SureTrackĀ® is a powerful value-added feature available with select Snap-on diagnostics tools. It offers an exclusive combination of expert knowledge and detailed parts replacement records, all wrapped in an interactive community.
