What trouble codes are you getting? From symptom description, seems a wire connection is loose somewhere andnot providing sufficient connectivity.

The trouble code would help to determine which circuit is at fault.

The trouble code was P0501 vehicle speed sensor which did not help when they replaced it. They also replaced the wheel bearing. The tech said he checked all of the wiring. Do you think it could have anything to do with the rack and pinion? Would it be connected to the ABS in any way?

A truble code means a circuit has a malfunction and it does not necessarily mean a sensor is bad. The wiring circuit , sensor or control modules are all possible causes. The mechanic replaced the sensor and bearing without confirming that they are bad indicates he is not up to the mark.

Since parts had been replaced and they did not solve the problem, you would need to test the wiring circuit and control module. Unplug the control module and look out for signs of contminations, water entry etc.

I believe you have the electronically controlled power steerign system and yes, the speed sensor can affect it as it is related.
