• Remove the spring compressor.

5. Final Assembly:

• Tighten the mounting bolts once again to ensure proper fitment.
• Apply anti-seize compound to the threads of the suspension bolts.
• Reinstall the suspension components in reverse order of their removal.
• Connect the negative battery terminal.

6. Test Drive and Alignment:

• Take your vehicle for a test drive to ensure everything is working properly.
