my last rack, if i stood by the drivers door car off or on, and rocked the wheel and put my other hand on the tire, i could feel a knock.
car was having a bit of a drifting issue too. but not bad. then i added the 3.4 and all and the car started to just pull what ever way it wanted to when on the gas, let off back on the gas and it was pulling the other way now.
after this that same knock was worse and the wheel had more play.
so with one wheel jacked up, i had a friend push and pull one tire, while i held the other side, it had no play tie rod wise, but it did have a lot of back and fourth play with the steering wheel locked you could see, and feel how much play.
installed a new rack, that knock when the wheel is rocked is gone and the car no longer pulls like a tard when hard on the gas.
