of fore axle
(c) Check for horizontal bending of fore axle.

• Overlook fore axle from right above,

and check if the line suspended and

the tie line of center bolt holes of the 2
leaf springs are aligned.

fore axle. Then you should correct it using a
press under room temperature.
(d) Check for fore axle distortion.

• Observe from one side, and check if the

2 test prods are upright and overlapped.

If not, it indicates fore axle distortion. Then
correct.

(e) Check for vertical bending of fore axle.
• Check if the 2 leaf spring seats of fore axle are in the same plane.
If not, it indicates vertical bending of fore axle. Then correct or replace with a new fore axle.
