SOURCE: How to replace s500 control arms How much do they

To replace the lower control are you need to unbolt it from the subframe, airmatic strut, sway bar link and from the lower ball joint. The lower ball joint is separate from the lower control arm. The ball joint actually gets pressed into the steering knuckle. Then the lower control arm sits on top of the ball joint and gets bolted down. The lower control arms list price are about $330 each and the ball joints are around $78 each for oem mercedes parts. The total labor for both to be replaced is somewhere between 6-8 flag hours. The thrust arms are also part of the front suspension and those arms are one piece that have a ball joint as part of the arm. The lower control arm usually doesn't need to be replaced unless its damaged since the control arm bushings are available separately and are around $73 each side for the kit.

According to Autozone.com, you must replace the whole control arm. Here is their procedure:
NOTE do not begin the removal procedure unless a new strut-to-lower arm nut, a new ball joint pinch bolt/nut and a new lower arm-to-front subframe bolt/nut are available.

  1. Remove or disconnect the following:
    NOTE
    Do not use a hammer to separate the ball joint from the front wheel hub and spindle.



    WheelsLower arm strut nut and dished washer. Discard them.
  2. Place the steering wheel in the unlocked position.
    NOTE
    Do not allow the halfshaft to move outward. Over-extension of the halfshaft joint could result in separation of internal parts, causing failure of the halfshaft joint.
  3. Remove or disconnect the following:

I need to replace the front king pin in the r/h side wheel of my El fairmont.. how do I do this ??


I take it that this is a Ford car in which case I doubt very much that it has king pins in the front end. It will have either an upper and lower ball joints in control arms or a lower ball joint on the end of a strut. Ford ball joints are riveted in from factory and the rivets have to drilled out and the new ball joints will have the correct bolts to replace the rivets IN the case of a strut the lower ball joint is replaced as above and the strut will have a replaceable insert in it that you can remove and fit a new insert in place . Ford stopped using king pins when they gave away "I" beam front axles .

Upper and lowere control arm replacement


Where you buy your ball joints usually will rent (for free, just pay for it and then return it is what they do) a ball joint press. It's an easy job if you have any mechanical skills at all. The strut is what keeps the pressure on the spring, using the weight of the vehicle to compress the spring, just undo the strut, raise vehicle and the spring will relax and you can remove the upper control arm.

The easiest way is too remove the whole knuckle and remove the joint on a bench. The Ball Joint is in the knuckle, not in the lower control arm. Try to not break pinch bolt on lower strut clamp. Hope this helps.. :-) Cobra

Need to replace the lower control Arm. Is there a procedure available?


Please be mindful to carefully note the position of the old parts as you disassemble the suspension, then follow these steps to do the re-installation:

REMOVAL

1. Disconnect the negative battery cable.

2. Raise and safely support the vehicle.

3. Remove the wheel and tire assembly.

4. Remove and discard the tension strut-to-control arm nut, then pull off the dished washer.

When separating the control arm from the steering knuckle, do not use a hammer. Be careful not to damage the ball joint boot seal.

5. Remove and discard the control arm-to-steering knuckle pinch bolt. Using a small prybar, spread the pinch joint slightly, then separate the control arm from the steering knuckle. A drift punch may be used to remove the bolt, but be very careful not to damage the ball joint boot seal.

Do not allow the halfshaft to move outward, or the tripod CV-joint internal parts could separate, causing failure of the joint.

6. Remove and discard the lower control arm inner pivot bolt and nut.

7. Remove the lower control arm from the frame and the tension strut.

INSTALLATION

Make sure the front washer is at the strut-to-lower control arm attachment.

8. Insert the strut into the inner bushing.

9. Position the lower control arm into the subframe bracket, using a new nut and bolt. Tighten to 73-97 ft. lbs. (98-132 Nm).

10. Assemble the lower control arm ball joint stud to the steering knuckle, making sure the ball stud groove is positioned properly. Be very careful not to damage the lower control arm seal.

11. Insert a new pinch bolt and nut, then tighten to 40-53 ft. lbs. (53-72 Nm).

12. Clean the strut threads to remove dirt and/or debris.

13. Install the dished washer, with its dished side away from the control arm bushing. Install a new nut on the strut and tighten to 73-97 ft. lbs. (98-132 Nm).

14. Install the wheel and tire assembly, tightening the lug nuts to 85-105 ft. lbs. (115-142 Nm), then carefully lower the vehicle.

I hope this helps.
