Volkswagen Tech Tip: Humming Noise From Front of Vehicle During Cornering

A humming sound coming from the general area of the front end may be noticeable on 1998 Beetles during slow-speed turning with the steering wheel almost to the full turning position. The noise may be generated from the differential spider gear contacting the one-piece thrust washer under load. In addition, the noise goes away when the steering wheel is returned to the center position.

You have probably seen some reality TV shows where the “builder” will pull a spark plug wire to confirm they have spark. This is one of the most misleading tests for the ignition system. If the spark plug produces a spark, the spark is at 14.6 psi (normal air pressure at sea level), not 170 psi or more inside the cylinder during the top of the power stroke.
