Need pitman arm replaced and idler arm replaced

I'm guesing you have had your tires balanced and wheels aligned. If this does not help, then you have a broken belt in one of your front tires.

The first thing to do is to have your alignment checked again. Wear on the inside edge usually points to an excessive negative camber problem caused by a bent suspension component or something like a worn ball joint. In some cases it can be caused by excessive toe out.
Alignment shop will be able to diagnose what is causing the neg camber.
Throwing parts at it is not a good idea could be just one part or multiple parts acting together. That's why a reputable alignment shop is in order.

Idler arm and or pitman arm most common.could also be excessive play in steering gear box.Tie rods/center link but usually its my first 2 choices go bad bothe of them idler and pitman common wear parts.

The most likely cause is a worn ball and socket (not the 'ball joint' on the suspension) on the Pitman arm for the steering linkage. The steering idler arm's ball and socket may also be worn. The parts are cheap, but it is a PITA to remove the Pitman arm. This can be checked by seeing how much steering wheel play you have before the wheels do anything. Looking at the Pitman arm while doing this may scare you. I drove with a bad one for ~1 year, and was always scared the ball was going to pop out of the socket and result in no steering.

You could have a bad tie rod end, Idler arm, pitman arm, wheel bearing or ball joint. All of these will normally cause a vibration also. Check by jacking the front end one side at a time and moving the tire back and forth on front and back and in and out on top and bottom. Either watch or have someone else watch the steering assembly for movement and where it is. If there is no unusual movement, it is more than likely an alignment problem or tire problem.

You could have a worn idler arm and pitman arm. The idler arm is more common to wear out before the pitman arm so start with that and have the front end aligned. Inspect all your front end steering components for damaged and worn out parts that need to be replaced.
Thank you for using Fixya, you did replaced your brake rotor when you replaced the brake pads right???

you will have to remove the steering gear box to change the pitman arm. the idler arm is on the other side by the passenger wheel. one nut and two bolts going threw fender take it off.

jack up and support van passenger side first with wheels straight remove wheel unbolt idler arm from center link and using a fork designed for removing front end parts some auto stores let u borrow / loan u fork remove idler arm unbolt (2) from frame replace and bolt in new one replace wheel other side wheels straight jack and remove wheel mark pitman at steer box so u can transfer mark to new pitman unbolt and us fork to remove pitman from center link us pulley to remove pitman transfer marks to new arm align up replace bolt up replace wheel done

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

tire pressure low,alignment jack up the front end and wobble the tires side to side the body lift would not effect this
