See Figures 1 and 2
Four wheel drive trucks covered by this manual utilize a front axle which drives the wheels through 2 halfshafts. These shafts utilize CV (Constant Velocity) joints to allow for suspension and drivetrain movement. The CV-boots (which are installed over the joints) should be checked for damage each time the oil is changed and any other time the vehicle is raised for service. These boots keep water, grime, dirt and other damaging matter from entering the CV-joints. Any of these could cause early CV-joint failure which can be expensive to repair. Heavy grease thrown around the inside of the front wheel(s) and on the brake caliper/drum can be an indication of a torn boot. Thoroughly check the boots for missing clamps and tears. If the boot is damaged, it should be replaced immediately. Please refer to Chapter 7 for procedures.
