CommonShock /struts AbsorberQuestions
6. Do I need to align my tyres after I have my struts replaced?
It depends on the vehicle design. A strut by design is also a component that supports the wheel & tyre. Some models aren’t affected when the struts are replaced while others do change the wheel alignment. Strut removal & installation potentially changes the position of the tyre alignment. Some struts have adjustment slots to perform the alignment with. All struts affect alignment in some way so it’s best to check the specific vehicle service manual and specifications.
7. What is the difference between a monotube and a twin-tube design?
By far, most vehicles (cars & trucks) in the world come factory-equipped with a twin-tube style shock or strut; probably 85% or more. The twin-tube is cost-effective and performs very well when the vehicle is operated within its designed purpose and for average, everyday use. In many other model vehicles, when the manufacturer designs a vehicle for more than average driving conditions, they often choose a monotube style shock. It’s a bit more costly, but has a quicker response rate, has no performance fade due to aeration and can automatically add performance just when needed. For vehicles factory-equipped with twin-tubes, the monotube replacement shock absorber becomes a performance upgrade opportunity. It can increase a vehicles handling and stability without dramatically decreasing ride comfort.
8. Can worn shocks or struts cause my new tires to wear unevenly?
Absolutely. Shocks and struts provide damping force to control tire movement. When the tires move excessively, they develop a “cupping” wear pattern that damages the tyre. Other factors such as incorrect air pressure, worn suspension components or improperly aligned steering also causes uneven tyre wear.
9. If I have a twin-tube shock can I switch to a monotube shock?
Yes; for many vehicles that come factory-equipped with a twin-tube, nafurancar offers a monotube (Gas-a-Just) as a performance upgrade. This will increase the vehicle’s handling and stability beyond the factory design. Please use the nafurancar catalogue to see if there is a monotube available for your specific vehicle.
11. I noticed a light film of oil on the shaft of my shock/strut do I need to replace them?
Probably not; a small amount of oil is normal and is used to lubricate the polished shaft and the upper seals. However if the unit is extremely wet or dripping oil, the unit should be inspected by a qualified technician.
