  Q: How to replace the shock absorber on Buick Park Avenue?

  A:

  First handle the Coil Springs gently when replacing the strut assembly to protect their protective coating which reduces their lifespan. Start by removing the strut mount retaining bolts followed by raising and supporting the vehicle to remove the tire together with the wheel. The front wheel speed sensor connector needs disconnecting then remove the speed sensor bracket from the strut. Hold onto the knuckle after stripping away the bolts between the strut and knuckle to stop damage to the Ball Joint or wheel drive shaft. Remove the Brake Line bracket from the strut then remove the strut to steering knuckle bolts and nuts before extracting the strut outside of the vehicle. Installation process starts with vehicle lowering before inserting the strut back into its original position. Install the strut mount to body retaining bolts with torque reaching 50 nm (37 ft. Lbs.). After lifting the vehicle a second time install the strut onto the steering knuckle by putting bolts and nuts in place then tighten them to 185 nm (136 ft. Lbs.). Mount the Brake Line while retaining bolt as you install the speed sensor bracket with retaining bolt and reach tolerance of 17 nm (13 ft. Lbs.). After reconnecting the abs front wheel speed electrical sensor connector, you can install the tire and wheel assembly while lowering the vehicle to complete the procedure with a front wheel alignment.

  Q: What Tools Are Required to Service and Repair Front Coil Springs and Shock Absorber on Buick Park Avenue?

  A:

  Proper servicing and repairing of the suspension strut demands several basic tools: the toolkit for suspension strut servicing requires holding fixture (J 3289-20) and strut compressor (d 34013-B) and alignment rod (J 34013-38) and damper rod clamp (J 34073-20). Holding fixture (J 3289-20), strut compressor (d 34013-B), alignment rod (J 34013-38), and damper rod clamp (J 34073-20). To start the process you should remove the entire strut assembly from your vehicle. The strut compressor (d 34013-B) receives the strut until its spring achieves a small level of compression through force screw rotation. A socket device should hold the strut shaft from rotation while the technician removes the strut shaft retaining nut. After inserting the alignment rod (J 34013-38) to lead the strut shaft from the assembly you can loosen the compressor screw while guiding the strut shaft out until both the strut and spring can be removed. To install the strut position it inside the strut compressor (d 34013-B) while mounting the damper rod clamp (J 34013-20) onto the strut shaft. If you removed the bearing from the upper spring seat during recovery install it now facing out from the centerline. Lay the spring properly over the strut before placing the assembly into the vertical position inside the strut compressor while installing the upper locking pin. Follow these steps to use the alignment rod (J 34013-38) in the strut guide strut shaft: use the compressor screw to turn clockwise as you guide the rod toward the center strut shaft. After adjusting the compressor forcing screw to reveal the strut shaft threads at the top of the strut assembly install the washer and retaining nut. Uncap the strut shaft's damper rod clamp (J 34013-20) then torque the strut mount nut to 75 nm (55 ft. Lbs.) with the socket maintaining grip on the strut shaft. After removing the strut from the compressor you should reinstall the complete strut assembly back into the vehicle.
