Q: How to replace a tie-rod end on a Saturn LS and LS1?
A: Loosen the wheel lug nuts, raise the front of the vehicle and support it securely on jackstands. Apply the parking brake and block the rear wheels to keep the vehicle from rolling off the jackstands. Remove the wheel. Loosen the tie-rod end jam nut using two wrenches. Mark the relationship of the tie-rod end to the threaded portion of the tie-rod to ensure the toe-in setting is restored when reassembled. Remove the cotter pin and loosen the nut from the tie-rod end ballstud a few turns. Disconnect the tie-rod end ballstud from the Steering Knuckle arm with a puller. Remove the nut from the ballstud, separate the lie-rod end from the steering knuckle, then unscrew the tie-rod end from the tie-rod. Thread the tie-rod end onto the tie-rod to the marked position and connect the tie-rod end to the steering arm. Install the nut on the ballstud and tighten it to the specific torque. Install a new cotter pin. If necessary, tighten the nut a little more to allow insertion of the cotter pin. Never loosen the nut to align the cotter pin holes. Tighten the jam nut securely and install the wheel. Lower the vehicle and tighten the lug nuts to the specific torque. Have the front end alignment checked and, if necessary, adjusted.
