SUSPENSION
l Tighten the nut up to approx. 53mm. protrusion of
the anchor bolt and fit the lock nut and tighten it.
l Remove the jack, bounce the wheel to settle the
suspension.
l Measure the front chassis height from the ground,
if it is not 550 + 3 mm. adjust it by torsion bar
anchoring bolt.
7. WHEEL ALIGNMENT
Following order is to be maintained while doing
wheel alignment
i) Camber angle
ii) Caster angle
iii) Toe-in
iv) Wheel lock angle
Caution
Not following the above order will lead to incorrect
wheel alignment even though individual
adjustments are done correctly.
Note
All adjustments for wheel alignment are to be done
in UNLADEN CONDITION ONLY.
Following precautions to be taken before
commencing wheel alignment.
l Vehicle should be unladen and parked on level
surface.
l Front tyre should have uniform wear and inflated
to correct pressure.
l Height of front LH & RH Hub cap centre from
ground level should be equal (Counter check for
even tyre wear and inflation).
l Ensure that hub play is correct. (Refer front axle
group)
l Ensure that the silent bushes in the front
suspension are in satisfactory condition.
l Ensure that the front suspension fasteners are
tightened to specified torque.
l Ensure that there is no play in steering linkages
and suspension ball joints.
l Checking and adjusting the steering geometry is
to be done in the proper order i.e. 1st camber
followed by castor and then toe-in.
Note
In case wheel aligning system is available please
follow instruction manual of manufacturer.
7A. CAMBER ANGLE ADJUSTMENT (Fig.22)
l While adjusting camber angle nobody should sit
inside the vehicle.
l To adjust camber angle, add or remove shims
between the chassis frame and the spindle of
upper wishbone mounting.
l Adding shims will reduce the camber angle and
removing shims will increase the camber angle.
Adjust camber angle to 00+ 30'.
Note
After addition or removal of shims tighten the
bolts to 18 mkg Recheck the camber angle.
7B. CASTOR ANGLE ADJUSTMENT (Fig.22)
l Adding shim at location ‘A’ will reduce the castor
at location ‘B’ will increase the castor. Adjust
caster angle to 30 + 30' as shown in (Fig. 22)
l Check castor angle. If castor angle is not within
30 + 30' add only one shim of 0.8 mm thick at
location ‘A’ or ‘B’ as shown in (Fig.22)
Note
LH/RH caster variation - 45'
After adding shim tighten the bolts to 18 mkg.
torque. Recheck the castor angle.
7C. TOE-IN ADJUSTMENT (Fig.23)
l The reading at the front of wheel rim should be
less than the reading at the rear of wheel rim by
2 to 5 mm.
l Toe-in is adjusted by varying the length of tie
rods after loosening their hex nuts. After adjusting
the length of tie rods recheck toe-in and tighten
back the hex nuts. Increasing length of tie rod
will reduce the toe-in and vice-versa. While
adjusting toe-in, adjust the length of both the tie
rods by rotating them in the same direction such
that their lengths remain equal at all times.
Precautions
To maintain the steering linkages symmetrical to
the vehicle centre line, centralise the linkages
i.e. the distance between chassis frame long
member outside face and centre of centre link
ball joint should horizontally equal (55 mm) at
both RH & LH sides. Hold the steering wheel in
this will ensure that when the wheels are in
straight ahead position, the steering linkages will
also be centralised.
