1. Perform diagnostic system check. See DIAGNOSTIC SYSTEM CHECK. After performing diagnostic system check, go to next step. 2. Turn ignition off. Spray right front wheel speed sensor jumper harness thoroughly with a 5 percent saltwater solution (2 teaspoons of salt to 12 ounces of water). Disconnect EBCM/EBTCM connector C1 (”W” body), connector C2 (”J” body, Cutlass and Malibu) or 32-pin connector (Achieva, Alero, Grand Am and Skylark). See EBCM/EBTCM LOCATION under REMOVAL & INSTALLATION. Using DVOM, measure resistance between speed sensor signal high circuit and speed sensor signal low circuit of EBCM/EBTCM connector. On “W” body, resistance should be 1020-1137 ohms at 68°F (20°C). On “J” body, Achieva, 1998 Grand Am and Skylark, resistance should be 1530-1870 ohms at 68°F (20°C). On Alero, Cutlass, 1999 Grand Am and Malibu, resistance should be 950-1250 ohms at 68°F (20°C). If resistance falls within this specified range, go to next step. If resistance is not within this specified range, go to step 11) .

PRE-ALIGNMENT CHECKS Ensure steering wheel is centered and front wheels are in straight-ahead position (to correct, shorten one tie rod adjusting sleeve and lengthen the opposite sleeve in equal amounts). Ensure none of the following conditions exist: Incorrect vehicle ride height (see RIDE HEIGHT ). Incorrect tire pressure, mismatched tires (differing size or type), excessive tire runout, unbalanced tire and wheel assemblies, loose wheel bearings, or loose wheel lug nuts. Loose or worn steering linkage/suspension components, or excessive play in steering gear box. CAMBER & CASTER ADJUSTMENT “C”, “G” & “K” Series Except 1999 Sierra & Silverado C1500 & C2500 (Caster Adjustment) 1. Check frame angle. See “C”, “G”, “K” & “P” (FRAME ANGLE) . If corrected caster is not within specification, remove frame bracket slots. See “C”, “G” & “K” SERIES (FRAME BRACKET SLOT REMOVAL) . Reset caster by loosening nut on end of each cam bolt securing upper control arm to frame brackets. See Fig. 18 . 2. Rotate cam bolts until caster is within specification. See WHEEL ALIGNMENT SPECIFICATIONS table. Tighten nuts to specification. See TORQUE SPECIFICATIONS table.

NOTE: BALL JOINT CHECKING NOTE: See SPECIFICATIONS & PROCEDURES article in WHEEL ALIGNMENT. Ball joint must be removed for the following checking procedure. See LOWER CONTROL ARM and BALL JOINTS under REMOVAL & INSTALLATION. Remove ball joint and place in vise, with ball joint stud pointing upward. Flip stud back and forth about 5 times. Reinstall the ball joint nut. Place torque wrench on ball joint nut and turn nut continuously 1 turn every 2 to 4 seconds. Read torque measurement on 5th turn. See BALL JOINT TURNING TORQUE SPECIFICATIONS table. If torque is not within specification, replace ball joint. WHEEL BEARING CHECKING NOTE: Wheel bearings are not adjustable. Whenever bearings are removed, replace with NEW bearings, races and oil seals. 1. Remove front wheel. Remove brake caliper and disc. Support caliper out of way. Using dial indicator placed near center of axle hub, check backlash by moving hub in bearing shaft direction. If backlash exceeds .002″ (.05 mm), replace bearing. 2. Check deviation at axle hub surface, outside of hub bolt by moving hub with twisting motion. If deviation is more than .002″ (.05 mm), replace bearing. Reinstall disc, brake caliper and front wheel. See Fig. 1 and Fig. 2 .

CAUTION: Use of incompatible bearing lubricant could result in premature lubricant breakdown. The recommended wheel bearing lubricant is the lithium-base grease High Temperature 4×4 Front Axle and Wheel Bearing Grease E8TZ-19590-A or equivalent meeting Ford specification ESA-M1C198-A. Sodium-base grease is not compatible with lithium-base grease and should not be intermixed. Therefore, before lubricating front or rear wheel bearings (1225), thoroughly clean all old grease from the bearing and front disc brake hub and rotor (1102). If bearing adjustment does not eliminate looseness or rough and noisy operation, clean and inspect the front disc brake hub and rotor and bearings. If bearing cups or the cone and roller assemblies are worn or damaged, replace. Disassembly 1. Raise vehicle and install safety stands. 2. Remove the wheel and tire. Refer to Section 04-04 in the Body, Chassis Manual. 3. Remove the locking hubs. 4. CAUTION: Do not let the disc brake caliper (2B120) hang only by the hose, or damage might occur to the hose or disc brake caliper. Remove the disc brake caliper. Refer to Section 06-03 in the Body, Chassis manual. Securely wire the disc brake caliper to the frame. 5. For vehicles equipped with automatic locking hubs, remove C-ring or snap ring and three-piece thrust washers (spacers). Remove the cam assembly and wheel bearing nut retaining key. Remove wheel bearing retainer (nut) using Hub Nut Wrench T95T-1197-B. Repack the wheel bearings with the specified lubricant (grease). For vehicles with manual locking hubs, remove snap ring, three-piece thrust washers (spacers), the outer lock nut, lockwasher, and inner lock nut using Spanner Locknut Wrench D85T- 1197-A or equivalent. 6. Remove the front disc brake hub and rotor. The front outer wheel bearing will slide out as the hub is removed. 7. Remove the retaining nuts of the front wheel spindle (3105). Carefully remove the front wheel spindle from the knuckle studs and halfshaft (3A329). If necessary, lightly tap the end of the spindle with a rawhide hammer to remove. 8. Clean old grease from the needle bearings and the bore seal of the front wheel spindle. To replace spindle bearing or inner seal, refer to Section 05-03A or Section 05-03B. 9. Clean any old grease or dirt from these parts and replace if signs of excessive wear are noted. Assembly 1. Using High-Temperature 4×4 Front Axle and Wheel Bearing Grease E8TZ-19590-A or equivalent meeting Ford specification ESA-M1C198-A, thoroughly lubricate the needle bearing and coat the front wheel spindles or face that mates with the seals of the front wheel spindle. 2. Assemble the front wheel spindle over the halfshaft onto the knuckle studs. Tighten the retaining nuts to 68-81 Nm (50-60 lb-ft). 3. Remove the front inner wheel bearing, wheel hub grease seal (1190) from the front disc brake hub and rotor using Bearing Cup Puller T77F-1102-A and Impact Slide Hammer T50T-100-A. Inspect bearings and replace as necessary. 4. Inspect the bearing cups for pits or cracks. If necessary, remove with a drift. If new cups are installed, install new cones and rollers. 5. Lubricate the bearings with High Temperature 4×4 Front Axle and Wheel Bearing Grease E8TZ-19590-A or equivalent meeting Ford Specification ESA-M1C198-A. Clean all old grease from the front disc brake hub and rotor. Pack the cones and rollers. If a bearing packer is not available, work as much lubricant as possible between the rollers and the cages. 6. Position the front inner wheel bearing in the inner cup and install the new wheel hub grease seal using a hammer, Driver Handle T80T-4000-W and the proper seal installer.
