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 UNLADEN CONDITION ONLY.
c) Only TOE-OUT value at front has to be
adjusted while doing wheel alignment. Rest of
the values remains fixed i.e. NO adjustments
are required. Refer the given table for standard
values.
1. Steering rack & pinion gear comes with
1260.2±3 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. Rotate the steering wheel from lock to lock.
Measure the number of turns.
3. Bring the steering gear to centre by rotating
through half the number of measured turns.
4. Remove the steering wheel & refit it so that
spokes & mascot (T-emblem) are correctly
positioned.
5. Ensure that both front tires are in straight
ahead position. Tighten the steering wheel nut
to specified torque.
6. Fix the outer ball joints into the steering arm of
suspension and rotate the steering wheel to
bring the spokes to the correct position.
7. Adjust toe-out as given below.
b)
Toe-out 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-out and
vice-versa.
c)
While adjusting toe-out, adjust the
length of both tie rods by rotating them in the
same direction such that their lengths
remain equal at all times.
8. Check the position of the T-emblem and 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.
NOTE:
After setting / adjusting steering geometry (i.e.
Toe), connect the diagnostic tool and follow
the instruction for ECU learning. This is
applicable for all variants fitted with EPAS.
