STEERING 20 1.3.3.5 DO’S & DON’TS DON’TS 1. Never lift steering gear by holding bellows. 2. Never store steering gear resting on its bellows. 3. Never store / transport steering gear with bellows fouling with other objects. 4. Never remove port plug before connecting with mating parts. 5. Never use cotton waste which will cause contam- ination. 6. Do not adjust ball joint nuts except during wheel alignment 7. Never lift steering gear by holding IBJ’s. 8. Do not remove the protective cap from the input shaft during transit or before assy. 9. Do not remove the protective cap from the OBJ during transit or before assy. NOTE Bellow is a seal. Do not use sharp tools near bellows if it can damage bellows. ! CAUTION Damaged bellow or absence of clip can cause water ingress and subsequent failure of Power steering. DO’S 1. Lift steering gear by holding mountings / body / cylinder only. 2. Store / transport steering gear resting on body / cylinder only. 3. Use steering gears on ‘first in first out’ basis. 4. If any steering gear is dropped, inspect for dam- age before using. 5. If any bellow is found damaged, replace it imme- diately with a good part & with proper position of clips 6. If any bellow clip is found missing, do not use the defective steering gear. Instead use another new steering gear 7. If the steering gear is off the vehicle, all ports should be covered with protective plugs to avoid contamination. 1.3.3.6 WHEEL ALIGNMENT Wheel alignment is a procedure of aligning wheels according to the specifications. The purpose of these adjustments is to give maxi- mum tire life and vehicle-travel that is straight and true when driving along a straight and level road. A correct wheel alignment is necessary because it af- fects directional stability, tire tread wear and vehicle’s safety. Warning signs of improper wheel alignment include steering wheel shimmy, a constant steering pull to one side, tire squeal noises when making turns, ex- cessive vibration as speed accelerates, and changes in direction after a car has hit a bump on the road. If any of the above symptoms are noticed, wheel alignment becomes necessary. Wheel alignment should be done at the time of fitting new tires and thereafter at regular intervals. Wheels which may be only a fraction out of alignment can scrub or drag along the road instead of rolling along it. Normally overall wheel alignment refers to the pro- cedures used to check and adjust the steering system, including the camber, caster, and toe. Basically toe is a measurement of how much the front and/or rear wheels are turned in or out from a straight ahead position. When the wheels are turned in, toe is positive (+). When the wheels are turned out, toe is negative (-). The purpose of toe is to ensure that the wheels roll parallel. Toe also serves to offset the small deflec- tions of the wheel support system that occur when the vehicle is rolling forward. In other words, with the vehicle standing still and the wheels set with toe-in, the wheels tend to roll parallel on the road when the vehicle is moving.
