Tracker Without Rear Wheel Anti-Lock Brakes

1. Park vehicle on level surface. Remove all luggage and passengers. Ensure fuel tank is full, and spare tire and jack are installed correctly.
2. Push LSPV against stopper bolt. Measure spring length. Spring length should be 3.9" (99 mm). See Fig 1. If spring length is not within specification, adjust stopper bolt until correct length is obtained.
