I have a pretty bad steering wheel shake when driving down the road, at all speeds. The steering wheel feels loose and I tracked it down to the pinion on the steering gear, which has about a half inch of play (I haven't taken it out yet). I looked on rock auto for a new rack, but they only have an FWD one. JNZtuning has the 4ws rack listed for $1400. I would really like to keep the 4ws, but I can't go for a part that expensive. Are there any alternatives?
