Jeff is describing how to replace the front wheel bearings. In the front, the bearing is part of a "hub cartridge". Randy is describing how to change the rear bearings on a truck with a "dead" rear axle. The sort of differential which is one massive cast iron assembly from rim to rim. However, your truck has an IRS [Independent Rear Suspension] design. You need to remove the wheels, brakes & the complete rear knuckle assembly. To remove the bearing from the knuckle requires a hydraulic press and a "knife edge" bearing removal tool. I doubt that you have these tools available. If not, find an auto parts store or auto machine shop with these tools. They can press the old bearing out and install the new one for you. Then you can reassemble the knuckle assembly from that point on. The video linked below should help you.
Basic tools..remove wheel, remove axle nut, remove brake caliper, remove lower control arm bolts,remove the bolt for upper control arm, remove the outer tie rod bolt, support vehicle and suspension, the hardest part is getting the axle out of the rear diff, sometimes a simple pry bar will pop it out, but I've run into a lot where you either need the special pickle fork or even have to remove the complete rear diff with axle still attached, remove cover and take out c clip.if you continue prying and hammering between inner cv joint and diff, you will cause damage to diff.the cv joint is steel, cast maybe, and diff is aluminum so guess what will be damaged first? That'll lead into a pretty expensive repair.the special tool to remove axle is 205-529
remove inner cv boot, just on inside edge is circlip which holds inner bearing joint into outer housing remove circlip and separate joint outer housing does not come out of front diff unless you drop or remove whole front diff assembly will have to remove whole stub axle hub assembly to remove drive shaft from outer wheel stub axle (hub) assembly
take wheel off take big nut off cv shaft so it can slide out of hub assembly, take bolt out that holds strut to hub assembly an bolt lower ball joint and tie rod end take hammer and tap knuckle where steering end attaches, pry out ball joint and take axle end out of hub assembly. then carefully with pry bar pop it out of tranny. when install cv axle push in tranny fast so that you feel it snap in. good luck
In order to change the cv joint, you will need to remove the wheel and the brake caliper and rotor. Raise vehicle on jack stands. Remove the wheel and remove the brake pads and caliper. Tie the caliper up out of the way, do not disconnect the brake line attached. Once the caliper is removed, slide the rotor off. Using the correct size socket, remove the nut in center of hub. Some vehicles have a kotter pin in the shaft just in front of nut. If so, remove pin before nut. Next, you will need to loosen a few bolts that hold the strut to the hub assembly. Once you have hub free from strut, turn the hub either left or right while having someone push in on the cv joint while turning joint left or right. Doing so will allow the joint to slide out of hub. Next, using a pry bar, insert between end of transaxle and transmission and pry out. To install new axle, align the axle with transmission and slide into transmission. Carefully work the other end of axle into the center of the hub assembly. Once you have it in the hub, tap gently with a rubber mallet until you hear it "pop" into transmission. Once it is in transmission, replace the bolts connecting the hub to strut. Replace nut on center or cv joint and tighten just until it seats against the hub...do not overtighten. Replace kotter pin with new pin. Slide the rotor over the studs, replace caliper and brake pads, install wheel and you are done.
remove inner cv boot, just on inside edge is circlip which holds inner bearing joint into outer housing remove circlip and separate joint outer housing does not come out of front diff unless you drop or remove whole front diff assembly
will have to remove whole stub axle hub assembly to remove drive shaft from outer wheel stub axle (hub) assembly
SECTION 205-05: Rear Drive Halfshafts
2002 Explorer/Mountaineer Workshop Manual
REMOVAL AND INSTALLATION
Protector, Differential Seal 205-506
Remover, Front Wheel Hub 205-D070 (D93P-1175-B) or equivalent
Remover, Halfshaft 205-502 Removal and Installation NOTE: This procedure applies to both rear halfshaft assemblies.
CAUTION: Do not loosen the rear axle wheel hub retainer until after the wheel and tire assembly are removed from the vehicle. Wheel bearing damage will occur if the wheel bearing is unloaded with the weight of the vehicle applied. With the vehicle in NEUTRAL, raise and support the vehicle. For additional information, refer to Section 100-02 .
Remove the rear wheel and tire assembly. For additional information, refer to Section 204-04 .
NOTE: Have an assistant press the brake pedal to keep the axle from rotating. Remove and discard the rear axle wheel hub retainer and the washer.
CAUTION: To prevent damage to the brake hose, do not allow the disc brake caliper to hang suspended from the hose. Remove the brake disc.
Remove the two bolts and lift the disc brake caliper and brake pads off the brake disc.
Using mechanics wire, position the disc brake caliper out of the way.
Remove the brake disc.
Remove the bolt retaining the parking brake cable bracket to the frame.
CAUTION: Cover the stabilizer link bolt threads and the nut to prevent boot damage when removing the halfshaft assembly from the vehicle. Using a rubber hose approximately 37.5 mm (1.5 in) long, cover the stabilizer link bolt threads and nut.
WARNING: The bolt that retains the upper ball joint to the knuckle is longer and it has fewer threads than the bolt that retains the toe link to the knuckle. Switching these bolts during installation will prevent the pinch arms on the knuckle from correctly retaining the toe link to the knuckle. This may cause the toe link to separate from the knuckle during vehicle operation. Failure to follow these instructions may result in personal injury. Remove the pinch bolts and disconnect the toe link and upper ball joint from the knuckle.
CAUTION: Support the rear suspension upper arm to prevent boot damage when removing the halfshaft assembly from the vehicle. Using a wood stick, approximately 450 mm (18 in) long and 25 mm (1 in) wide, support the rear suspension upper arm.
CAUTION: Do not use a hammer to separate the outboard CV joint from the hub. Damage to the threads and internal CV joint components may result. CAUTION: Once the outboard CV joint separates from the hub the knuckle will continue to pivot until the brake backing plate presses against the suspension lower arm. To prevent damage to the brake backing plate, immediately after separating the outboard CV joint from the hub, rest the knuckle on a cushioned support that is tall enough to keep the backing plate from pressing against the suspension lower arm. Separate the outboard CV joint from the hub and rest the knuckle on a cushioned support.
Using the special tool, press the outboard CV joint until it is loose in the hub.
Remove the special tool.
Separate the outboard CV joint from the hub.
Rest the knuckle on a cushioned support.
CAUTION: Do not damage the axle shaft oil seal or the machined sealing surface on the inboard CV joint housing. CAUTION: Do not allow the splines on inboard CV joint housing to touch the axle shaft oil seal. NOTE: A circlip retains the inboard CV joint housing to the differential side gear in the axle. Using the special tool, disengage the inboard CV joint housing from the differential side gear.
CAUTION: To prevent damage to the axle shaft oil seal, install the special tool before removing the inboard CV joint housing from the axle. Install the special tool.
Remove the halfshaft assembly from the vehicle.
CAUTION: To prevent damage to the axle shaft oil seal, install the Differential Seal Protector before positioning the inboard CV joint housing in the axle. CAUTION: Always install the halfshaft with a new retainer circlip and a new rear axle wheel hub retainer. CAUTION: Never use power tools to tighten the rear axle wheel hub retainer. To install, reverse the removal procedure.
athere is a snap ring within the CV joint the nedds to be spread OPEN to release CV joint from axle, Once CV is cleaned and repacked with grease rintall onto axle by again spreading apart clamp. Prior to installing CV joint slide NEW CV joint boot onto axle, Cleanly intall add'l grrease and reinstall CV boot.
