Ball Joint Preventive Maintenance:
  Some ball joints use zerk grease fittings, which allow for periodic lubrication of the moving ball and stationary socket inside the ball joint. Grease fittings can sometimes be found on other suspension components and need to be lubricated as part of a preventive maintenance program provided by the OEM.

Loaded Upper Ball Joint Play Measurement:

  The most common problem in the suspension system is play, or looseness of the parts. Although many of the parts are designed with special connections that allow for movement to accommodate movement of the wheels, excessive play is actually a bad thing. Excessive play magnifies the feel of road imperfections and makes the steering less responsive to steering wheel input. Excessive play is potentially very damaging, as it causes wear on the connecting parts and tires. Naturally, any amount of play in a fixed part is problematic and is frequently a result of part failure. Remember, unwanted looseness in the suspension system can be extremely dangerous and should be corrected as soon as possible.

Picture(A)
1.Obtain a properly sized block of wood to fit between the upper control arm and the frame.
2.Place the block of wood between the upper control arm and frame so that it is secure.

Picture(B)
3.Raise the vehicle by lifting the body, using the specified lift points, so that the tire is a few inches off the ground. Support the body with a jack stand.
4.Place a dial indicator on the upper control arm and vertically against the steering knuckle.

5.Place a pry bar under the tire, and pry it upward, watching the dial indicator reading as you pry and release. Record the total amount of movement in the joint, and compare to the OEM specifications.

Picture(C)
6.Rock the bottom of the tire in and out, watching for play in the lower ball joint, and compare to OEM specifications.

Loaded Lower Ball Joint Play Measurement:

1.Jack up the vehicle, place safety stands under the control arms, and look up the exact procedure in the online service information.
2.Place a dial indicator on the lower control arm and vertically against the steering knuckle.

3.Place a pry bar under the tire and pry it upward, watching the dial indicator reading as you pry and release. Record the total amount of movement in the joint, and compare to the OEM specifications.
4.Rock the top of the tire in and out, watching for any play in the upper ball joint specifications.

Frequently Asked Questions
(1).What common symptoms indicate front ball joint need to be replaced?
1.Clunking noise from front tires.
2.Steering wheel shakes.
3.Car moves to the right or left, especially going over the bumps.
4.Vehicle tires have abnormal wear.

(2).Is it safe to drive with a ball joint problem?
  The ball joint connects the control arm to the steering knuckle. As the wheels – and therefore the steering knuckles – move, the ball joints help the suspension – and therefore the control arm – stay steady. And as the suspension moves, the ball joints help the wheels steer. When the ball joints fail, the suspension and wheels have a hard time working independent of each other. This puts unnecessary strain on each component, which can alter wheel alignment and severely damage the suspension.

(3).Are worn ball joints dangerous?
  Yes, it can be quite dangerous. Because, a worn ball joint causes suspension damage, inspection failure, and breakage of related parts.
  It might make your front suspension come apart while driving, so the wheels move in whatever direction inertia takes them. That can lead to a fatal accident.

(4).What happens if I don't replace ball joints?
  If you don't want to replace your ball joints, then get ready to experience some serious issues. The old ball joints cause mysterious clunking noise or drifting steering. Once they are worn-out, it will seriously affect your steering and suspension. However, you do not need to change the ball joints if it is new.

(5).Do I need to grease new ball joints?
  I would say it will be a wise decision if you grease your new ball joints. At least I will always grease a new one after the installation. Greasing a new ball joint will make it stronger and extend its lifetime because there is a minimal amount of grease inside. I suggest you do so after the first installation. Follow the instruction card.
