Installation Guidelines

Professional installation is recommended for this component. Ensure the vehicle is properly supported and secured before beginning any work. Refer to your vehicle's service manual for specific torque specifications and procedures.

Key Installation Aspects:

• Wrench Flats: The design includes wrench flats for easier tightening and loosening of fasteners.
• Initial Greasing: Although pre-greased from the factory, it is recommended to grease the component upon installation to ensure the boot is fully filled and mating surfaces are lubricated.

Maintenance

Regular maintenance, particularly greasing, is crucial for maximizing the service life and smooth operation of your MOOG K90677 Suspension Stabilizer Bar Link.

Greasing Procedure:

• Inspection: Before greasing, inspect the component for any damage, such as cracked, split, or torn boots, or excessive looseness/free play. If any of these conditions are present, the part should be replaced before greasing.
• Grease Fitting: Locate the grease fitting, typically threaded into the dome cover plate of the tie rod end or ball joint.
• Application: Use a hand grease gun to slowly pump grease into the fitting. Avoid using high-pressure grease guns aggressively to prevent damage to the boot.
• Purpose: Greasing allows fresh lubricant to flow to critical areas, ensuring the ball stud movement is well-lubricated and the socket is full of grease. This process flushes out contaminants, reducing corrosion and wear, and prolongs the component's life.
• Grease Type: MOOG engineers recommend using a heavy-duty lithium or synthetic-based grease.
• Intervals: It is recommended to grease these components at every oil change to ensure regular lubrication.
