Front Suspension & Wheel Alignment: Adjustments Jeep Compass I рестайлинг 2

PRE-WHEEL ALIGNMENT INSPECTION

Before any attempt is made to change or correct the wheel alignment, the following inspection and necessary corrections must be made to the vehicle to ensure proper alignment.

1. Verify the fuel tank is full of fuel. If the fuel tank is not full, the reduction in weight will affect the curb height of the vehicle and the alignment specifications.
2. The passenger and luggage compartments of the vehicle should be free of any load that is not factory equipment.
3. Check the tires on the vehicle. The tires are to be inflated to the recommended air pressure. All tires must be the same size and in good condition with approximately the same tread wear.
4. Check the front tire and wheel assemblies for excessive radial runout.
5. Inspect all suspension component fasteners for looseness and proper torque.
6. Inspect the lower front ball joints and all steering linkage for looseness and any sign of wear or damage.
7. Inspect the rubber bushings on all the suspension components for signs of wear or deterioration. If any bushings show signs of wear or deterioration, they should be replaced prior to aligning the vehicle.
8. Check vehicle curb height to verify it is within specifications. Refer to «WHEEL ALIGNMENT, STANDARD PROCEDURE»(ref-612691-S13249886242014043000000) .

WHEEL ALIGNMENT SETUP

1. Position the vehicle on an alignment rack.
2. Install all required alignment equipment on the vehicle, per the alignment equipment manufacturer's instructions. On this vehicle, a four-wheel alignment is recommended. NOTE: Prior to reading the vehicle's alignment readouts, the front and rear of vehicle should be jounced. Induce jounce (rear first, then front) by grasping the center of the bumper and jouncing each end of vehicle an equal number of times. The bumper should always be released when vehicle is at the bottom of the jounce cycle.
3. Read the vehicle's current front and rear alignment settings. Compare the vehicle's current alignment settings to the vehicle specifications for camber, caster and toe-in. Refer to «WHEEL ALIGNMENT, SPECIFICATIONS»(ref-612691-S37673915672014043000000) .

ADJUSTMENT BY SHIFTING CROSSMEMBER

1. Loosen the four bolts fastening the front crossmember to the frame just enough to allow movement of the crossmember. Refer to and «CROSSMEMBER, FRONT SUSPENSION, REMOVAL»(ref-612698-S06684408652014043000000) .
2. Loosen the bolts fastening the fore/aft crossmember to the frame just enough to allow movement of the crossmember. Refer to «CROSSMEMBER, FRONT FORE AND AFT, REMOVAL»(ref-612698-S24995802862014043000000) . CAUTION: When shifting the front crossmember, keep in mind that the front and rear engine mounts are attached to the front crossmember and fore/aft crossmember and should be inspected following the crossmember shift to make sure they are properly aligned.
3. Shift front crossmember as necessary (See following tables) to bring camber or caster into specifications. When shifting crossmember, use care not to move other angles (camber or caster) that are within specifications, out of specifications.

4. Tighten all previously loosened fasteners (bolts) securing the crossmember to the vehicle to specifications. Refer to «CROSSMEMBER, FRONT FORE AND AFT, INSTALLATION»(ref-612698-S24169639622014043000000) and «CROSSMEMBER, FRONT SUSPENSION, INSTALLATION»(ref-612698-S15878104752014043000000) .
5. Jounce the rear, then front of the vehicle an equal amount of times.
6. Measure camber and caster. If camber and caster are within specifications, refer to «TOE»(ref-612691-S28656748002014043000000) . If camber cannot be brought into specifications, perform the CAMBER ADJUSTMENT BOLT PACKAGE INSTALLATION below.

CAMBER ADJUSTMENT BOLT PACKAGE INSTALLATION

The camber adjustment bolt package contains new bolts and nuts for attaching the strut clevis bracket to the steering knuckle. The bolts contained in the package are slightly undersize allowing for movement between the strut clevis bracket and the steering knuckle. The movement allowed by the undersize bolts provide approximately two degrees of camber adjustment per side of the vehicle. To install and adjust the camber adjustment bolt package, follow the procedure below.

Scheme 3

1. Raise the vehicle until its tires are not supporting the weight of the vehicle. Refer to «HOISTING, STANDARD PROCEDURE»(ref-612692-S42044915732014043000000) .
2. Remove the wheel mounting nuts (3), then the front tire and wheel assembly (1). CAUTION: The strut clevis-to-knuckle attaching bolt shanks are serrated and must not be turned during removal. Remove the nuts while holding the bolts stationary, then tap the bolts out using a punch.
3. Remove the original upper bolt (1) and nut (3) attaching the strut clevis bracket (2) to the knuckle (5).
4. Install a bolt from the adjustment package into the hole where the original bolt was removed. Install the bolt as indicated.
5. Install a nut provided in adjustment package on the replacement bolt. Tighten the nut until it's snug, but still allows the knuckle to slide in the clevis bracket.
6. Remove the original lower bolt (6) and nut (4) attaching the strut clevis bracket (2) to the knuckle (5).
7. Install a bolt from the adjustment package into the bottom hole of the strut clevis bracket. Install the bolt as indicated.
8. Install a nut provided in adjustment package on the replacement bolt. Tighten the nut until it's snug, but still allows the knuckle to slide in the clevis bracket.
9. Install the tire and wheel assembly (1). Refer to «INSTALLATION»(ref-612693-S31957631432014043000000) . Install and tighten the wheel mounting nuts (3) to 135 N.m (100 ft. lbs.).
10. Perform the above procedure to opposite strut as required.
11. Lower the vehicle and jounce the front and rear of the vehicle.
12. Adjust the front camber to the preferred setting by pushing or pulling on the top of the tire. When camber is set to specifications, tighten the upper and lower strut clevis-to-knuckle attaching bolt nuts (3, 4) enough to hold the adjustment. Again jounce the front and rear of the vehicle, then verify the camber settings.
13. Tighten the front strut clevis-to-knuckle attaching bolt nuts (3, 4) to 110 N.m (81 ft. lbs.).
14. Once camber is within specifications, adjust toe to meet the preferred specification setting. Refer to «FRONT TOE»(ref-612691-S09654500162014043000000) within this wheel alignment service procedure.

Scheme 4

1. Center the steering wheel and lock it in place using a steering wheel clamp. NOTE: When setting toe, make sure to set rear toe to the preferred specifications before setting front toe to the preferred specifications
2. Remove the steering wheel clamp.
3. Remove the alignment equipment.
4. Road test the vehicle to verify the steering wheel is straight and the vehicle does not pull or wander.
