Replace Shock Absorber, Why, When & How.
Do you know why shock absorber is so important for driving?
Because it makes sure safety and comfort
- Proper fitment result in safer & comfortable driving conditions.
- Replace shock absorbers periodically
- Do check for damages
What are the problems caused by worn out shock absorber?
- Excessive shaking on the unpaved road
- Unstable ride at high speed
- Excessive nosedive and squat during acceleration and braking
- Longer stopping distance
- Tyre bouncing on a bumpy road
- Bad fuel consumption
When should we replace the shock absorber?
- Uneven tread wear shows the shock absorber are worn out
- When your car tends to drift or bounce when you experience loss of handling control
- When your car keeps rocking while you push the hood down
- When your car is bouncing continuosly
- When you hear a stange and unfamiliar sound from the shock absorber
What is the purpose of shock absorber?
- Keeps tyres firmly on the road
- Better road grip and control
What is the sign of a dead shock absorber?
- Dents on the outer casing
- Bend on the piston
- Damaged bushes and washers
When do you recommend to change the shock absorber?
- Generally you need to replace the shock absorbers every 20,000 kms
Can we replace one shock absorber alone
- Do not replace one shock absorber alone
- Always replace all the shock absorbers at one time
What grade shock absorber suits my car?
- Sets higher that OE, not down than OE
- If original shocks are Oil= set Oil (44/63/66 series) or Twin Tube Gas (34/36/33 series) or Mono Tube Gas (55 series)
- If original shocks are Twin tube Gas= set Twin tube Gas (34/36/33 series) or Mono Tube Gas (55 series), No Oil Shock (44/63/66 series)
- If original shocks are Mono Tube Gas= set Mono Tube Gas (55 series), No Oil Shock (44/63/66 series) and No Twin Tube Gas (34/36/33 series)
What is the advantage of Gas Shock Absorbers?
- Stable road grip
- Better comfort on rough roads
How safe are reconditioned Shock Absorbers?
- No adequate damping force
- Harmful to human life
- Less durability makes frequent replacement
Is life span of gas shock absorbers more than that of oil shock absorbers?
- Both gas and oil shock absorbers have same life span
Can I check damping force of the shock absorber by hand testing?
- Shock absorbers should not be hand tested
- Aactual damping force cannot be checked by hand
How about KYB’s damping force?
- KYB shock absorber’s damping force is always more than genuine shock absorbers
How to store the shock absorbers?
- Do not store the shock absorbers in upright position
- Always store them in flat position
Points to be noted before installation
- Hold the shock abosorbers vertically
- Pull the piston rod/cover right up to the maximum expansion
- Press down the piston rod/cover to the maximum compressed length
- Do this operation at least 4 to 5 times
- This operations allows to prime the shock absorber
Points to be noted before installation
- Always use a new lock nut while using a new shock absorber
- While installing the brake hose, make sure to release air bubles on all brake hoses
- Always use a torque wrench to tighten the lock nut
- Please check the manufacturers service manual for the torque required
- Replace the bumper stop in case of missing or broken
- Bumper stop is fitted on the shock absorbers to prevent bottoming and possible damages to the bottom compression valve of the shock absorber
- Remove the stabilizer link from the strut assembly and the braek hose
- Cap the tip of the hose to avoid spillage of the brake fluid
- Take off the bolts from the bottom attachment bracket
- Take off the attachment nut on the top and remove the strut assembly from vehicle
- Hold the strut assembly in a vice and set spring compressors on both sides and compress the spring
- Remove the lock nut located on top of the rod
- Take off the upper support assembly, spring seat, coil spring and dust boot
- Keep these parts in one location as they may be re-used for installation of the new shock absorbers
Always use the proper tools to replace the shock absorber like torque wrench and a pair of spring compressors
