Common Shock /struts Absorber Questions
1. What causes my vehicle to make clunking noises even though my shocks/ struts are new?
This is usually caused by a mounting problem and not the shock or strut itself. Check the components that attach the shock or strut to the vehicle. The mount itself may be worn enough to cause the shock/strut to move up and down. Another common cause of noise is that the shock or strut mountings may not be tight enough causing the unit to have some slight movement between the bolt and bushing or other attaching parts.
2. Can I compress my shock/strut too easily by hand. Does this mean the shock/strut is weak or defective?
You cannot judge the strength or condition of a shock/strut by hand movement alone. The force and speed generated by a vehicle in operation exceeds what you can accomplish by hand. The fluid valves are calibrated to operate differently depending on the degree of movement inertia which cannot be duplicated by hand.
3. When do I need to replace worn shocks or struts?
There are four main reasons that determine when to replace them:
To restore the vehicle’s designed performance (usually after 80,000 Km);
when the vehicle has excessive ride control conditions (i.e. nosedive, body roll, etc.);
when the vehicle has a failed unit (i.e. dripping hydraulic fluid, tyre cupping, excessive bounce, etc.); or
to upgrade performance
4. Should I consider replacing any other part while having my struts serviced?
Yes, it is also a good idea to replace both the strut mount and the protection kit when replacing struts. The strut mount optimizes suspension performance by providing a smooth steering response and reducing vibration. Protection kits will protect your new struts from dirt, dust, salt and leakage.
5. How do I know if a strut is rebuild-able?
Struts cannot be refilled or rebuilt. However, some struts have a replaceable cartridge. These repairable struts can be identified by a large hexagonal shaped nut at the top of the strut body.Please remember that struts are usually gas charged and that replacement should only be performed by a qualified technician.
