1995 Volvo Acl: problems, recalls and reliability

VEHICLE DESCRIPTION: CLASS 8 HEAVY DUTY TRUCKS. THE AIR SUSPENSION CONTROL VALVE SUPPLY LINE WAS NOT PLUMBED THROUGH AN AIR PRESSURE PROTECTION VALVE. IN THE EVENT OF A FAILURE, THERE WOULD BE LOSS OF AIR PRESSURE IN THE 'B' SYSTEM AIR RESERVOIR THAT SUPPLIES AIR PRESSURE FOR THE FRONT STEER AXLE BRAKES.

Remedy: DEALERS WILL INSTALL THE NECESSARY AIR PRESSURE PROTECTION VALVE.

UNDERCOATING APPLIED TO THE INSIDE OF THE CAB SHELL SQUEEZED OUT DURING ASSEMBLY ONTO THE BRAKE PEDAL PLUNGER.

Remedy: DEALERS WILL CLEAN THE UNDERCOATING FROM THE BRAKE PEDAL PLUNGER ASSEMBLY, LUBRICATE AND REINSTALL THE BRAKE PEDAL PLUNGER ASSEMBLY.

THE TRACTION SOLENOID EXHAUST CAN BE OBSTRUCTED DUE TO INADEQUATE DRAINAGE AND A BUILD-UP OF ROAD CONTAMINATION BETWEEN THE MOUNTING BRACKET AND THE SOLENOID HOUSING. THE OBSTRUCTED EXHAUST PREVENTS THE RELAY VALVE CONTROL AIR PRESSURE FROM VENTING AFTER A DIFFERENTIAL BRAKING TRACTION EVENT.

Remedy: DEALERS WILL REMOVE THE SUSPECT VALVE AND INSTALL A NEW VALVE THAT HAS A MODIFIED SOLENOID HOUSING WHICH WILL ALLOW FOR SUFFICIENT DRAINAGE AND A NEW VALVE MOUNTING BRACKET WITH INCREASED HEIGHT TO REDUCE ENTRY OF CONTAMINATION.

THE REAR SUSPENSION AXLE RETENTION PLATE CAN BREAK UNDER NORMAL USE, AFFECTING AXLE ALIGNMENT.

Remedy: DEALERS WILL REMOVE AND REPLACE THE AXLE RETENTION CLIP PLATES ON AFFECTED VEHICLES.

THE REAR MOST AXLE OF THE TANDEM AXLE SET COULD HAVE INOPERABLE BRAKES ON ONE OR BOTH WHEELS BECAUSE THE BRAKE S-CAM WAS INCORRECTLY INSTALLED.

Remedy: DEALERS WILL INSPECT THE BRAKE SYSTEM AND REPAIR THE S-CAM ASSEMBLY IF FOUND REVERSED.
