Power Steering

From BMW E34 Encyclopedia

Symptoms[edit]

  • Steering might feel fine for few hours after installing the new belt, then it begins to squeal/kickback as you attempt to turn the steering wheel. This will tend to happen during a complete stop or at a low RPM range.
  • No symptoms when car is in full motion

Causes[edit]

Harmonic Balancer[edit]

One of the most overlooked parts that might cause your steering problems is a harmonic balancer. Most mechanics will suggest replacing tensioners, belts, pumps and even rack pinions before narrowing this problem down.

Loose V-Belt / Bad tensioner[edit]

A worn out v-belt or an improperly tensioned belt will omit similar symptoms. The tensioner should also be inspected and replaced.

Worn Out Idler/Adjusting pulleys[edit]

It's always a good idea to inspect your idler and adjusting pulley.

Low Power Steering Fluid[edit]

Check the level of your power steering fluid (black canister near the fuse box (driver side). You may have an undiagnosed leak within the system, or just need to add bit more power steering fluid.
