AXLE ADJUSTMENT
HENDRICKSON
The design of Hendrickson suspensions does not
provide for axle adjustment for alignment purposes. If
the axles are measured to be significantly out of
alignment, the following areas should be investigated as
the possible cause.
1.
Severely worn walking beam center or end bushings.
2.
Worn spring pins.
3.
Improper location of frame brackets on frame.
4.
Any worn or damaged parts.
