Important Service Tips for Control Arm Replacement
When replacing the front lower forward control arm, the steering knuckle tapered sleeve may become seized to the ball joint stud, causing a visual difference between the old and new parts.
It is essential to follow the factory service manual for removal procedures, as a special tool may be required to retain the sleeve in the knuckle bore.
Inspection and Re-use of Steering Knuckle Sleeve
If the sleeve needs to be removed from the ball joint stud for re-use, it must be separated carefully using penetrating oil and a three-jaw puller.
All rust and corrosion must be cleaned from the sleeve and steering knuckle bore, and the sleeve and mating component must be inspected for damage or abnormal wear.
Do not re-use the sleeve or mating component if signs of damage or abnormal wear are found during inspection.
