The idler isn't bad, Remove cotter pin going through the nut, take off nut, you need a seperator tool to pull apart the arm from the center link, once that is done, remove the two bolts holding it to the frame, remove arm, installation is just reverse.
The pitman arm is a little more to it. Do the same, remove cotter pin, take off nut, and seperate it from the rod, now there is big nut holding it on to the bottom of the steering box, take that nut off (some are a real pain), you will need a pitman arm puller to get it off. Note the position of the arm, need to put new one in same place, pull it off slow, sometimes seals will come with it, put seals back in same way, if they come out. Put some grease on splined shaft, tap new arm on until you can get nut on, tighten up with nut. Hopefully you have any problems. Good luck.

SOURCE: replace idler arm/pitman arm
Don't worry it is not too hard if you keep at. One "special tool" that you will need is a ball joint separator to separate the ball joint on the idler arm from the steering. When changing make sure to compare your replacement parts with the original and if necessary make a diagram of how things go together. On the bottom, there is a castle nut and a cotter pin. Remove the pin and loosen the nut then use the ball joint separator to remove the idler arm. (This is the hardest part of the job.) Then remove the remaining bolts and take the part off. Before putting the new idler arm make sure that you put the new grease fitting on it (and go ahead and squirt a little grease in it even though it already has some) and in between the new ball joint and the steering there should be a plastic bearing that slips into place. It's a pretty straight forward job and once you take a good look at it you will see what all needs to be done. Hope this helps, let me know how it goes. Goodluck!

Alignment has alot to do with the tires not shimmying.. Like zero toe setting. Loose componants like tie rod ends and the idler ar worn. You can ck for excess front end play by holding the front and back of the wheel and pushing and pulling on it, like rocking it. OR have someone rock the steering while you watch where the play is from underneath. By rocking I mean turn the steering wheel back and forth. Look at all th joints and pivot points for excess play, which is, movement not immediate to the rest of the steering system. Tire balance is very important. Wheel hop is a sign of a bad tire and it overtaxes the shock absorber. Shocks don't cause shimmy because they are a vertical movement controlA shimmy is lateral or side to side.Wheel balance weights must be spit. If a 2 oz. weight is needed to balance the tire, Oe once should be on the inside of the wheel and one ounce on the outside directly across from each outher.. Loose wheel brgs will cause shimmy, but they would not last long. Caster setting on the wheel alignment will also cause shimmy. Like on a shopping car. too much caster causes the wheel to start fluttering and is very hard on other componants. This may be why you have worn tie rod ends and a bad pitman arm. Worn control arm bushings and ball joints directly affect titre wear and can only be feltwhen the front end hits a dip and detected by side wear on the tire edges. Summary: replace the tie rod end and have the car aligned. Good Luck, -Ned_ sorry about the book

Provided as to wether or not your model has a steering damper (if smo, may likely need replacing) and the ball joints check good, it may be likely that you have a worn steering gear. Many types are adjustable or rebuildable.

I have had both the Pitman and Idler Arms,seize almost the same day, on a veh still under warrantee.
I have also replaced many over 45 years,just as general maintenance,before they caused,tire wear or worse. So no big deal!
The other issues will be solved,most likely, by removing the steering wheel and replacing the Clock Spring. Then the air bag will be happy and your wheel buttons,computer and radio, can once again,communicate and work properly.
Follow the proper proceedure in disarming the air bag,so you don't get hurt!!
