A technician needs to replace the coil spring on a MacPherson strut assembly that has been removed from a vehicle. What is the correct chronological order of steps required to safely disassemble the strut assembly?
- 1Secure the removed strut assembly in a specialized bench fixture or holding vise.
- 2Attach an approved spring compressor and compress the coil spring until tension is relieved from the upper spring seat.
- 3Loosen and remove the center retaining nut from the top of the damper piston shaft.
- 4Lift off the upper mount assembly and slide the compressed coil spring off the strut body.
Answer
The correct sequence is: first secure the strut assembly in a bench fixture, next compress the coil spring with an approved compressor tool, then remove the damper shaft center retaining nut, and finally remove the upper strut mount and slide the spring off the strut body.
The correct procedure starts by securing the strut in a bench fixture. Next, the coil spring must be compressed with a spring compressor to relieve the preload acting against the upper spring seat. With spring tension relieved, the technician safely removes the center shaft retaining nut, and then removes the upper mount to slide the coil spring off the damper.
