Hi,

The clicking you hear is likely the cause of a rubber coupling in the motor driven power steering unit (MDPS). There is actually a technical service bulletin (TSB) related to the clicking. If you look at pic 1, it shows the coupling I'm referring to.

As you can tell, it isn't something that is easy to replace. In fact, to replace the coupling requires disassembly of the MDPS and computer programming to get it properly working again. Honestly, I feel this is a dealer repair unless you feel comfortable and have the tooling needed.

Here is the actual TSB. The remaining pics will correlate with this TSB.
