Freightliner Spring (Tandem)
Equalizer Bushing Checking
1. Block the frame up enough to take the weight of
the chassis off of the springs. Attempt to move
the equalizer up and down, by using a pry bar
between the top of the equalizer and the top of
the equalizer bracket. Apply hand pressure only.
See Fig. 3. If movement at the center of the
equalizer exceeds 1/8 inch (3 mm), replace the
equalizer bushings.
2. With the vehicle unloaded, attempt to move the
equalizer side to side using a pry bar between
the equalizer and frame rail. Apply hand pressure
only. See Fig. 4. If clearance between the equal-
izer assembly and any frame component or fas-
tener is less than 1/8 inch (3 mm), replace the
equalizer bushings.
Freightiner AirLiner Component
Clearance Checking
Check that the air line support brackets are posi-
tioned so the air lines do not rub against anything.
Reposition any configurations that could contact and
result in friction and wear. There must be at least 1
inch (25 mm) clearance around the rubber air spring
