Q: How to replace a tie-rod end on a Mercury Cougar?
A: Loosen the wheel lug nuts. Block the rear wheels and set the parking brake. Raise the front of the vehicle and support it securely on jack stands. Remove the front wheel. Hold the tie-rod end with a wrench and loosen the jam nut enough to mark the position of the tie-rod end in relation to the threads. Remove the cotter pin and loosen the nut on the tie-rod end stud. Disconnect the tie-rod from the spindle arm with a puller. Notice the nut has been loosened, but not removed - this will prevent the components from separating violently. Remove the nut and separate the tie-rod. Unscrew the tie-rod end from the tie-rod. Thread the tie-rod end onto the marked position and insert the tie-rod stud into the spindle arm. Tighten the jam nut securely. Install a new nut on the stud and tighten it to the torque. Install a new cotter pin. Install the wheel and lug nuts. Lower the vehicle and tighten the lug nuts to the torque. Have the alignment checked by a dealer service department or an alignment shop.
