How do you change a tie rod end to a Pontiac Aztec 2003?

Outer or inner? I've only done the outer ones

Loosen wheel lug nuts. Raise and support on jackstands. Chock rear wheels and set parking brake.

Remove wheel.

Loosen tie rod ball stud nut. Loosen jam nut. Remove ball stud nut. Mark tie rod (so you know approximately where new tie rod should end up) or count threads as you're removing the old tie rod end.

Install new tie rod. Install ball stud into steering knuckle. Tighten ball stud nut. Tighten jam nut. Check torque specs on the ball stud nut, tighten to spec, then put the cotter pin in stud to keep the new stud nut from backing off.

If you bought "greaseable" ends, you'll need to grease them.

If you need outer tie rods, check am-autoparts.com. They offer one or a pair of greaseless outer tie rod ends and they're under $50. If you go to the auto parts stores, they'll charge you at least $35 apiece for them!

Hope this helps!
