Shock Absorber, Gray/Red, Rear

Start shock absorber servicing by taking away both the wheel and tire then support the rear axle with suitable jack stands or supports. Move forward by taking off the upper shock nut alongside washer and insulator assembly that you should throw away. When reassembling the shock absorber system maintain at least 40 Nm (30 lb-ft) of torque on the upper components. The shock absorber service starts with removal of the lower shock nut bolt combination which will be disposed. When reinstalling the lower shock components use torque to a value of 90 Nm which equals 66 lb-ft. Replacement of shock absorbers should be performed individually when needed while using new fasteners having an equivalent part number to achieve proper performance and safety. Proper suspension system integrity depends on using correct torque specifications for reassembly processes. It is crucial to never apply heat or flames on the gas pressurized shock absorber or strut tube because they may explosively explode and risk serious bodily harm. Similarly all physical parts need to stay away from shock absorbers and strut rods to prevent injury.

The first step for replacing the rear shock absorber demands turning off electricity to air suspension to avoid unintended air spring inflation or deflation because such changes could trigger vehicle shift while servicing. All vehicles containing fire suppression systems need to have their depowering function completed before moving forward. Position the car in NEUTRAL gear then set it on a hoist after supporting the rear axle through appropriate jack stands or a suitable jack. After removing the upper shock nut together with the washer and insulator you should discard these components followed by new part installation where the upper nut gets tightened to 40 Nm (30 lb-ft). The shock absorber installation requires removal of the lower shock nut and bolt followed by installation of the new absorber part where the nut must be tightened to 90 Nm (66 lb-ft). After finishing the installation you must trigger the fire suppression system if your vehicle contains one. Shock absorber replacement requires identical fasteners to their original part number or essential equivalent models since inferior parts or substitute designs will deteriorate performance and raise maintenance expenditures. The correct retention of components depends on following all specified torque values during reassembly operations. The installation of shock absorbers happens one by one and manufacturers do not require you to replace absorbents in sets.

Professional servicing of gas pressurized shock absorbers requires strict care due to the uncontrolled extension ability which threatens bodily harm. A spring compressor must be used for shock absorber and spring disassembly procedures because of the intense operational loads. The proper functioning of essential systems depends on suspension fasteners' performance because replacement parts need to match original numbers exactly and torque specifications from assembly must be notably followed for effective retention. The first step involves removing the shock absorber with spring assembly but you should avoid tightening the vise beyond necessary force to prevent shock absorber tube damage. Tag the upper mount as well as the spring and shock absorber for future reassembly orientation. Check the spring part number on the new spring against the part number written on the Vehicle Certification label to verify spring code accuracy. An appropriate spring compressor should compress the spring while you should hold the shock absorber rod to remove and discard the nut. The assembly of upper mount and dust boot should be removed from installation while you extract the spring by using the spring compressor. Additionally use the same marks on new shock absorbers and springs and upper mounts to align them to their original positions. Check the lower and upper spring seats for damage while examining the spring insulator for wear because replacing the upper mount may be required. Examine the spring for any signs of damage before installation because a new spring is required if any damage exists. The mechanic can install the shock absorber into the vise before adding the shock along with the spring compressor onto the strut. After proper alignment of the upper mount and dust boot against the disassembly marks you must install a new nut before eliminating the spring compressor to finish the installation of shock absorber and spring assembly.

Discard the nut and bolt, then tighten the new nut to 90 Nm (66 lb-ft) during installation.

Discard the nut and bolt, and tighten the new lower shock nut to 90 Nm (66 lb-ft).

Position the new shock absorber and spring assembly and loosely install the lower nut and flag bolt.

Suspension fasteners are critical components that affect the performance of vital systems.

Yes, shock absorbers can be installed individually as required, without the need to install in pairs.

The specified torque values for proper retention.

With the vehicle in NEUTRAL, position it on a hoist and support the rear axle with a suitable jack or jack stands.

Reverse the removal procedure.

Use new fasteners with the same part number or an equivalent, ensuring that torque values are adhered to during reassembly.

Position it and secure it with two anchor plate bolts tightened to 160 Nm (118 lb-ft).

Do not allow it to hang from the brake hose; instead, remove the two bolts and support the assembly with mechanic's wire, tightening it to 160 Nm (118 lb-ft) upon reinstallation.

Use the hex-holding feature.
