Mopar replacement. No instructions provided. I referenced a Haynes manual. The new ones had a different number of threads. This meant I couldn't count threads to get the alignment close. I had to measure. Also the Haynes manual sates 50 ft/lbs for the adjustin clamp bolts. I over tightened them using a calibrated torque wrench. Be carefull not to bend the bolt on the tie rod adjustment clamp. Alignment is required by a professional. Still and easy job. The removal required a puller. My pickle fork was almost useless with the old ones.
