Chrysler Steering Rack Return Problems

If your Chrysler develops a return problem – meaning the steering wheel returns slowly to the centre position after you turn it – the cause could be any of five slightly different problems, and you might as well approach them in this order to diagnose and fix the problem as inexpensively and quickly as possible.

Stiff or Seized Rack Internals

There are two directions of movement within a steering rack and if it is tight within the rack then there will be resistance in both directions of turn. Try to turn the steering wheel slowly through the full lock when the vehicle is stationary with the engine switched off. If it feels ‘notchy’ or requires more force to turn at any point then the problem is within the steering rack.

Pinion Preload Too High

Excessive preload causes the rack to hold the column shaft in such a manner to prevent smooth self-centring. In some Chrysler applications the pinion is known to have faulty ‘preload’ which can cause confusion with a ‘faulty valve body’. This is a typical example of why a correct diagnosis is so important before attempting repairs.

Hydraulic Pressure Imbalance

A worn pump or a partially clogged control valve can cause the same problems, due to uneven pressure on the rack. Low fluid, old fluid, dirty fluid or a whitening fluid can all indicate a worn pump. A whining or grinding noise from the pump when under load can also indicate worn pump components.

Tie Rod Binding

Tie rod ends which are over-tightened or have corroded can cause problems with steering return. Check the tie rods by jacking up the front of the car and gently trying to move them. If they feel stiff or are rough to movement, check for wear. Ideally they should move in a smooth, consistent arc.

Fluid Condition

The fluid in your car’s power steering system can get thick as it gets old. Check to see if your fluid is dark, smells burnt or looks contaminated. If it does, flush and re-fill your power steering system before starting your diagnosis of the slow return of the steering wheel.

Wait until you have established the likely cause of the problem before starting the repair. Otherwise, you could waste a lot of time and money trying to sort out a complicated fault.
