RIDING HEIGHT
Note. Riding height information not available.
Scheme 2
- For 2WD, raise front by centering floor jack under inner edge of lower control arm pivot bolt mounting bracket. To raise rear end, position floor jack under rear axle next to leaf spring mount. (Scheme 2)
- For 4WD, raise front end by placing floor jack under outside of front leaf spring mount and center it under front axle. To raise rear end, place floor jack under rear axle next to leaf spring mount. (Scheme 2)
| CAUTION | Never place jack under any part of vehicle underbody. DO NOT attempt to raise one entire side of vehicle by placing a jack midway between front and rear wheels, as permanent body damage could occur. |

RWD VAN
To raise front end, place floor jack under center of front crossmember, inboard of lower control arm pivot. (Scheme 3) To raise rear end, place floor jack under rear axle, next to leaf spring "U" bolt mount.
Scheme 3
HOISTING
| CAUTION | DO NOT raise vehicle by hoisting or jacking against front lower control arms. If rear axle, fuel tank, spare tire and liftgate will be removed for service, place additional weight on rear end of vehicle. This will prevent tipping as center of gravity changes. |
Scheme 4
- Vehicle may be raised on single or twin-post swiveling arm, or ramp-type drive hoists. If using swiveling arm hoist, ensure lifting arms, pads or ramps are positioned evenly on frame rails, and adequate clearance is maintained for transfer case (4WD models) or skid plate. (Scheme 2)and (Scheme 4).
- If twin-post hoist is used, a 4" x 4" x 12" wooden spacer may be required to maintain level vehicle. Position spacer under front axle tube (opposite differential housing). All hoists must be equipped with adapters to support vehicle properly.
To raise vehicle on single and twin post type hoists, ensure hoist pads contact vehicle frame behind front control arm pivots and inside rear wheels on rear axle housing. Always use appropriate hoist adapters. (Scheme 3)
2WD
Clean eccentric cam bolt threads. Record camber and caster measurements. Loosen cam bolt retaining nuts. (Scheme 5) Adjust camber and caster to specification. See WHEEL ALIGNMENT SPECIFICATIONS table. Tighten cam bolt retaining nuts to specification. See TORQUE SPECIFICATIONS.
Scheme 5
4WD
Camber is not adjustable on 4WD models. Caster angle may be adjusted using shims. Record caster measurements. Remove original caster shims from spring pads and add or delete shims to meet specifications. See WHEEL ALIGNMENT SPECIFICATIONS table.
Scheme 6
- Use Tool Set (C-4581) for this procedure. (Scheme 6) Position each tool with small hook attached to upper control arm frame bracket and large hook around pivot bar. Tighten adjustment nut on each tool until large hook is snug against pivot bar. Loosen both upper control arm retaining bolts completely.
- To obtain proper camber and caster angles, tighten or loosen tool adjustment nuts on each tool to move one or both ends of upper control arm. See «WHEEL ALIGNMENT SPECIFICATIONS»(ref-52334-S19182643722001011800000). Tighten pivot retaining bolts. See «TORQUE SPECIFICATIONS»(ref-52334-S27800955962001011800000).
RWD VAN & 4WD MODELS
Center steering wheel and hold with steering wheel clamp. Loosen tie rod adjustment sleeve clamp bolts. Rotate adjustment sleeve to align toe to specifications. See WHEEL ALIGNMENT SPECIFICATIONS table. Position sleeve clamps on underside of sleeve so that clamp ends are not over sleeve slot. Tighten adjustment sleeve clamp bolts to specification. See TORQUE SPECIFICATIONS . Remove steering wheel clamp.
EXCEPT RWD VAN & 4WD MODELS
Center steering wheel and hold with steering wheel clamp. Loosen tie rod lock nuts. Rotate rods to set toe to specifications. See WHEEL ALIGNMENT SPECIFICATIONS table. Tighten tie rod lock nuts to specification. See TORQUE SPECIFICATIONS . Adjust steering gear to tie rod boots at tie rod. Remove steering wheel clamp.
