Screw those stupid things. I tried to install them and they got all chewed up and destroyed no matter what I did. Since that one side has such a thin wall it kept catching on something and ripping. Piece of **** garbage. Not even worth my time to send back to summit. I used the grease and filed any problem spots down, pain in the ass crap. Then I go to the parts store and the guy looks at me like Im stupid when I ask for rack and pinion bushings. I hate stubbon old men who think they know everything, but its fun when you prove him wrong. Ran into the same problem with the 70 year old "Parts Pro" at Kragen who handed me a bag of needle bearings when I needed a pilot bearing.
