Common Shock Absorber Failure Reasons
Shock absorber failure can be grouped into 3 areas:
Oil leakage, physical defect or noise.
Oil Leakage
Normally oil leakage occurs as a result of damaged oil seal or bushing. Any damage to the piston rod can affect the oil seal.
Cause and Action
Damage due to worn out parts (Dust cover, bump rubber). Replace those parts, with new parts, and replace new KYB shock absorber
Damage by tools (plier etc) during installation of Shock Absorber). Do not hold piston rod by any tools. Replace new KYB shock absorber
Unsatisfactory installation of shock absorber causes irregularity. Correct installation with the right instruction or suitable tools.
Noise
Noise can be present as either a rattle or a swish. Any damage to the piston rod can affect the oil seal.
Cause and Action
Not using KYB supplied parts during installation, or use of other brand parts. Replace shock absorber using parts provided.
Damage by tools (plier etc) during installation of Shock Absorber). Do not hold piston rod by any tools. Replace new KYB shock absorber.
Incorrect bump or rubber used. Piston rod or internal components may be damaged by using wrong rubber. Replace shock absorber by using correct components.
Physical Defect
Physical defects are bent or broken shock absorbers.
Cause and Action
Pressure by frozen liquid put in the strut. Do not put any liquid in the strut housing.
Tightened with impact wrench. Do not use any power tools.
Cause and Action
Wrong Installation of shock absorbers and equivalent parts. Confirm KYB Instruction Sheet and Car Manufacturer Manual, and Replace Wrong parts or procedure.
