QA1 1210-299B GM Style Ball Joint

TOOLS AND SUPPLIES REQUIRED

QA1 Ball Joint Tool Kit p/n 1891-106
1” Wrench
1/2” Wrench
High Quality Lithium Grease

ADJUSTING PRELOAD ON THE BALL STUD

NOTE: Preload on the ball stud can be set with the ball joint attached to the control arm if the spring is unloaded and the ball joint taper is free from the spindle. Preload can also be set prior to installing the ball joint and can be done one of two ways.

Using the QA1 spanner wrench, loosen the lock nut by turning counter clockwise. Turn the torque nut to adjust ball stud preload until the stud has the least amount of rotational resistance with no up or down play in the housing. Final setting must allow for the lock nut to be fully seated in the housing.
Manually install the lock nut and spin clockwise until tight against the torque nut.
Using the QA1 hex key, a ½’’ open-ended wrench or socket, and the QA1 spanner socket, turn the lock nut clockwise while holding the torque nut, locking them together to 25 ft. lbs.
Re-check the preload on the ball stud and adjust as needed.
Using a grease gun, lubricate and rotate the ball stud by hand until the grease is visible on the bottom of the ball. If the ball joint is on the car, move the suspension up and down to get the same effect. Note: Excessive grease may result in hydraulic lock. If this occurs, move the ball stud until pressure is relieved and the ball stud freely rotates.

ALTERNATIVE INSTRUCTIONS

Using the QA1 spanner socket from Ball Joint Tool Kit (p/n 1891-106) loosen the lock nut by turning counter clockwise.
Using the QA1 hex key, torque the torque nut to 25-30 in. lbs. and then back off 90°.
Using the QA1 hex key, a ½’’ open-ended wrench or socket, and the QA1 spanner socket, tighten the lock nut while holding the torque nut, locking them together to 25 ft. lbs.
Re-check the lash on the ball stud and adjust as needed. The ball stud should not have any axial lash.
Using a grease gun, lubricate and rotate the ball stud by hand until the grease is visible on the bottom of the ball. If the ball joint is on the car, move the suspension up and down to get the same effect. Note: Excessive grease may result in hydraulic lock. If this occurs, move the ball stud until pressure is relieved and the ball stud freely rotates.

MAINTENANCE / REBUILDING OF BALL JOINTS

Grease using high quality lithium grease and check preload on a regular basis. Disassemble (follow instructions below) at least annually or every 2000-2500 laps or 3,000 miles, whichever comes first, to inspect all parts, clean, and re-adjust preload on the ball stud. Ball joint must be regularly checked for wear, and replaced accordingly.

NOTE:
QA1 Ultimate Ball Joints do not come with dust boots for quick and easy inspection. The following part numbers are available dust boots are desired.
9034-107 Upper Dust Boot
9034-106 Lower Dust Boot

Disconnect from the spindle:

Remove the spring and shock.
Place a jack stand under the lower control arm for support.
Make sure the control arm is near level and the taper of the ball joint is centered in the ball joint housing.
Use a pickle fork to push evenly on both sides of the ball joint housing until the taper is free from the spindle.
NEVER POUND THE BALL JOINT OUT BY THE BALL STUD!

Do NOT press on the ball stud to remove the ball joint from the control arm! Press on the housing only.

Ball Joint Disassembly:

Use the QA1 spanner wrench to remove the lock nut by turning counter-clockwise.
Use the QA1 hex key with a ½’’ open-ended wrench to remove the torque nut by turning counter-clockwise.
Remove the self-lubricating cup, steel spider, ball stud, and bearing race.
Clean all parts and inspect for excessive wear. Replace any parts that may be worn or damaged. The ball stud is concentric and should be checked for straightness. Place ball stud on a flat, clean surface and roll gently back and forth observing the stud. If there is a wobble in the stud, it is bent and must be replaced.

INSTALLATION

**IMPORTANT*** – QA1 does NOT recommend welding the ball joints to the control arm. However, if you choose to weld the housing to the control arm, you must disassemble and remove the self-lubricating cup and the steel spider. The bearing race should be left in the ball joint housing if you choose to weld. If the ball joint housing distorts due to welding, the race will not fit back inside. Be sure to minimize any welding procedure to prevent distortion of the ball joint housing. Welding is done at your own risk; QA1 does not warranty parts that have been welded.

Screw In
Apply anti-seize to the threads of the housing. Install the ball joint in the upper or lower control arm and tighten to 100 ft. lbs. Do NOT use the QA1 hex key, the QA1 spanner wrench or an air gun to screw the ball joint into the arm.

Bolt In
Install the ball joint on the correct side of the control arm and torque the mounting bolts per the recommended bolt specifications. Press In
Install the ball joint on the correct side of the control arm, ensuring you are pressing squarely only on the ball joint housing. When pressing in the ball joint, do NOT press on the lock nut or you will damage it. Press in using only the appropriate tool(s). Do NOT pound into place.

Connecting to the spindle:
The ball stud must be in full contact with the spindle taper from the top to the bottom. If the taper in the spindle does not fit the taper of the ball stud, it will appear to be tight at one end, but will have a gap at the other end, and will lead to failure of the ball joint.

Torque Spec
Follow minimum initial torque specs, then tighten till the first available slot aligns with the cotter pin hole.
