Coil Spring And Shock Absorber: Disassembly

WARNING: This page is about a different car, the 2006 Nissan Quest. However, it is still accessible from the selected car via links, so may be relevant.

Set the shock absorber (strut) in a vise, then loosen (without removing) the piston rod lock nut as shown.
CAUTION: Do not remove piston rod lock nut at this time.
Compress the spring using commercial service tool until the shock absorber (strut) mounting insulator can be turned by hand.
WARNING: Make sure that the pawls of the two spring compressors are firmly hooked on the spring. The spring compressors must be tightened alternately and evenly so as not to tilt the spring.
