TIRE WEAR - OUTSIDE EDGE DIAGONAL - REAR - TOE ADJUSTMENT PROCEDURE
FORD 1984-85 TEMPO
LINCOLN-MERCURY 1984-85 TOPAZ
Some dealers have reported that they cannot adjust rear toe on Tempo/Topaz vehicles following the procedures outlined in TSB 84-3-11. The following
provides a more detailed procedure which has proven successful by dealers on vehicles that could not be adjusted originally by following TSB 84-3-11.
This procedure requires two technicians for part of the procedure to perform a successful adjustment. Part A pertains to four-wheel alignment equipment,
and Part B pertains to two-wheel alignment equipment.
NOTE:
Alignment equipment with 4-wheel capability is preferred when checking/sening rear wheel too on Tempo/Topaz vehicles. If 4-wheel
equipment is not available, 2-wheel equipment may be used.
A - Four-Wheel Alignment Equipment
1.
Drive vehicle onto alignment equipment, making sure the wheels are set straight ahead.
2.
Attach the alignment heads and adjust for wheel runout as required.
3.
If the alignment rack does not have built-in slip plates for the rear wheels, place the portable slip plates under the rear wheels. Lower rear end of
vehicle and jounce.
4.
Individual total rear toe can be read and recorded. Total rear toe is the sum of the left and right toe.
5.
Reset the rear total toe and toe on each side as close to 0" as possible using the following procedure.
^
Loosen the rear lower control arm to spindle attachment bolts (1 R/S; 1 L/S).
^
Loosen both arms' (2 arms on each side) inner attaching bolts to floor pan bracket (2 R/S; 2 L/S).
^
NOTE: The rear wheels must be setting on slip plates while this procedure is performed. Do not have the rear wheels raised.
^
Grasp the tire at the front edge and at the rear edge and pivot the tire back and forth on the slip plates a few times to make sure the lower arms
are free to move in their loose attachments.
^
Pull outboard on the front edge of the tire and at the same time push inboard on the rear edge of the tire until the desired toe change is
obtained. Toe on each side should be as close to 0" as possible.
^
One technician must now hold the tire in this desired position while another technician tightens the control arm attaching bolts.
NOTE:
Two technicians are required to prevent the alignment setting from slipping back to original setting if the wheel is not held in desired
position.
Control arm to spindle bolt torque spec 80-115 N-m (60-86 lb.ft.). Control arm to body bolt torque specification 55-75 N-m (40-55 lb.ft.).
