recommendations and any other additional

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.
