2000 Volvo Acl

Component

Steering:Linkages:Tie Rod Assembly

Consequence of Defect

on some heavy duty class 8 vehicles equipped with arvinmeritor axle assemblies which may have been manufactured with trw model 20edl ball sockets, the tie rod ball-socket bearings have a below specification case depth and/or hardness which can lead to premature wear out of the socket in some applications.

Corrective Action

if this condition occurs, the driver can lose steering control, possibly resulting in a vehicle crash.

Recall Notes

dealers will replace the ball socket assemblies. this campaign supersedes nhtsa campaign nos. 01v-139.001 and 02v-037.002. owner notification began july 25, 2002. owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact volvo trucks at 1-800-528-6586.

Component

Suspension

Consequence of Defect

vehicle description: heavy duty 6x4 trucks equipped with chalmers 800 series suspension kits. these suspension kits may have insufficient penetration of the weld attaching the torque rod eye to the torque rod tube.

Corrective Action

failure of the weld could result in separation of the eye and tube, causing a lock of axle retention, which could result in loss of vehicle control.

Recall Notes

dealers will replace all chalmers fixed torque rods on these vehicles. chalmers is conducting the owner notification and remedy for this campaign. owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact chalmers at 1-905-624-9750.
