One problem related to steering rack and pinion has been reported for the 2006 Toyota Tacoma.
Front suspension instability, I have replaced the tires two times, and have replaced the oem shocks for the bilstein "oem trd" but the vehicle behaves like the front sway bar or the rack & pininion are loose. I have taken this vehicle to the dealer countless times but they are unable to notice the noise that comes from the front suspension or anything wrong. It is my perception that a design flaw or a defective part of the front suspension or rack & pinion have to be causing all of the instability. I really consider this vehicle very unsafe and hope to find the problem withim the next couple months or I will replace it for a tundra.
