(1) Remove dryer-to-compressor retaining screw
(Fig. 13).
(2) Rotate dryer assembly 90° to release retaining
tangs from exhaust solenoid housing and withdraw
unit.
INSTALLATION
Inspect O-Ring for damage and location on dryer
assembly.
(1) Insert and index air dryer locking tangs into
exhaust solenoid outlet.
(2) Rotate air dryer assembly to lock position and
install air dryer-to-compressor retaining screw (Fig.
13).
SOLENOIDS (STRUTS AND AIR SPRINGS)
Front struts and rear springs are equipped with so-
lenoids that control air pressure and volume within
the assemblies. The solenoids are electrically oper-
ated to allow air input, contain air, or release air
pressure, depending on control module commands.
REMOVAL
WARNING: DO NOT ATTEMPT TO REMOVE OR IN-
STALL
SOLENOIDS
WHILE
AIR
SUSPENSION
(FRONT STRUTS AND REAR AIR SPRINGS) ARE
SUPPORTING VEHICLE.
Disconnect negative battery cable. Raise vehicle
and remove wheel and tire assembly then remove so-
lenoid(s) as follows:
(1) Separate electrical connection to solenoid.
(2) Disconnect air line, see Air Lines and Fittings.
Solenoids have molded square tangs to fit into
stepped notches of the air spring housing. The
notches provide an air relief position and a retaining
position. The retaining position is locked with a re-
taining clip.
(3) Remove retaining clip (Fig. 14).
(4) Rotate solenoid to first step in housing and al-
low air pressure to vent (Fig. 15).
(5) Rotate solenoid to release slot and remove (Fig.
16).

INSTALL
(1) Inspect O-Ring condition and position on sole-
noid stem. (O-Ring can become dislodged during re-
moval (Fig. 16).
(2) Install solenoid with tangs to top ledge of hous-
ing and install retaining clip.
(3) Reconnect air line and electrical connection.
STRUT (AIR SUSPENSION) DAMPER
ASSEMBLY
Service procedures for removal and installation for
(air or steel spring) assemblies are essentially the
same. Except for air venting/recharging and discon-
necting/connecting air lines and electrical connection.
REMOVAL
(1) Disconnect battery negative cable.
(2) Hoist vehicle and remove wheel and tire assem-
bly.
(3) See AIR LINES AND FITTINGS and discon-
nect air line.
(4) Disconnect electrical leads, solenoid and height
sensors.

SUSPENSION and remove strut.
DISASSEMBLY/ASSEMBLE
Disassembly is restricted to upper mount and bear-
ing housing. The strut shock absorber, air spring
with integral height sensor, solenoid and wiring har-
ness are serviced as an assembly.
