  Q: How to inspect and replace the dust seals and ball joints for 4-wheel drive front suspension on Mazda B2000?

  A:

  Check the dust seals on cracks or brittle condition and change them in case of necessity. Test the end play of the ball joints of both upper and lower, and replace any with a greater end play than 0.10mm (0.0039 in.). The starting steps to replacement include lifting and placing of jackstands beneath the frame and the front end of the car, removing the wheels and holding the lower arm elevated with a floor jack to continue replacement. Removal of cotter pin and nut of the upper ball joint and separate it with the knuckle by use of ball joint separator tool. Take the bushings and dust seals off the ends of the upper arm shaft and then the nuts and bolts that hold the upper arm shaft with the support bracket and record the number and position of the shims so that they can be applied when the wheel is in position. Check the components of all parts to wear or damage any components being replaced. Test the ball joint preload using a pull scale and adapter and the reading should be 40 lb. or less when the ball joint stud is shaken. Unbolt and take out the ball joint of the arm, then reattach by reversing the steps of removal, and then torque the upper arm shaft mounting bolts to 60-68 ft. lbs., the ball joint-to-arm bolts to 15-20 ft. lbs. and the ball joint nut to 30-37 ft. lbs.
