In most cases, no.
Ironman 4×4 recommend strut assembly be performed only by a qualified automotive mechanic using specialised strut compressor equipment. Assembled struts store large amounts of sprung energy. Only mechanics with necessary tools and equipment should attempt to disassemble or assemble a strut. Mishandling of strut assemblies can result in severe injury or death. Never loosen or remove strut centre top nut until all spring energy is retained within a high quality strut compressor.
The shock absorber does not self-extend with gas pressure?
Ironman 4×4 Nitro Gas shock absorbers will self-extend due to pressurised nitrogen gas contained within, the rate of gas extension offers little relevance in determining the health or performance of the shock absorber.
Ironman 4×4 Foam Cell shock absorbers will NOT self-extend like a gas pressurised shock absorber as they do not contain gas pressure – A Foam Cell shock absorber will generally feel firmer to extend than it will to compress.
If a gas shock absorber fails to self-extend, this may not indicate a problem, it may simply be due to a dry or dirty piston rod, firm valving resistance or due to low gas pressure design. This does not adversely affect performance.
Avoid removing the thin film of oil from the piston rod, it is required for smooth seal operation and lubrication. A light oil may be used to rejuvenate the seal if a squeak is present.
