590 STEERING SYSTEM 1146 mm LH/RH variation in castor 45' Rear wheel alignment data (Unladen condition) Camber angle 0.75° (+ve) Toe-Out 9’ NOTE : (a) Please follow manufacturer’s (of tire replacement machine) manual for wheel alignment instructions, recommendations and any other additional information. (b) All adjustments for wheel alignment are to be done in UNLADENCONDITIONONLY. (c) Only TOE IN value has to be adjusted while doing wheel alignment. Rest of the values remains fixed i.e. NOadjustments are required. Refer above table for standard values. 1. Steering rack & pinion gear comes with 1146 mm (nominal) length between centers of the ball joints with tie rods parallel to the rack. (As shown in following figure) Ensure that number of threads of outer ball joints exposed out of the tie rod tube is same on LH and RH side 2. Mount the steering rack & pinion gear at its mounting location. Assemble the steering column with steering wheel. Do not tighten the steering wheel to full torque. 3. Rotate the steering wheel from lock to lock. Measure the number of turns. 4. Bring the steering gear to centre by rotating through half the number of measured turns. 5. Remove the steering wheel & refit it so that spokes & mascot (T-emblem) are correctly positioned. 6. Ensure that both front tires are in straight ahead position. Tighten the steering wheel nut to specified torque. 7. Fix the outer ball joints into the steering arm of suspension and rotate the steering wheel to bring the spokes to the correct position. 8. Adjust toe-in as given below. (a) Toe-in is adjusted by varying the length of tie rods after loosening their lock nuts (as shown in above figure). After adjusting the length of tie rods recheck toe-in and tighten back the lock nuts. Increasing length of tie rod will reduce the toe-in and vice-versa. (b) While adjusting toe-in, adjust the length of both tie rods by rotating them in the same direction such that their lengths remain equal at all times. NOTE : Toe - in is the difference in distance between the front of the wheels and the rear of the wheels . 9. Check the position of theT-emblemand the spokes. If the steering wheel is not centered, adjust the tie rod lengths by reducing one and increasing the other so that in the SAP (Straight Ahead Parked) condition the toe is correct and yet steering wheel is centered.
