ISSUE: Excessive wear on the inboard edges of the rear tires on 1986 and 1987 Taurus/Sable station wagons may be caused by camber and rear toe settings that are not within specification.
ACTION: To correct this, reset the camber and rear toe to specification. If the camber cannot be set to specification, install a new adjustable camber kit using the following service procedure. Refer to the chart that follows for rear alignment specifications.
REAR ALIGNMENT SPECIFICATION
Nom. Min. Max.
Camber (DEG) -0.7~ -1.9~ +O.1~
Toe-In (DEG) Per Wheel +0.06' -0.060 +0.18'
NOTE: Maximum side-to-side camber difference: 1.2~.
1. Inspect rear suspension for damage. Replace any damaged components before continuing to Step 2.
2. Measure and record vehicle rear wheel alignment settings for left hand camber, right hand camber, left hand toe, and right hand toe.
- If vehicle is in specification for camber but out-of-specification for toe, reset toe to nominal specification of +0.06~ toe-in for each individual wheel.
- If both camber and toe are within specification, reset toe to nominal specification of +0.06~ toe-in for each individual wheel.
- If vehicle is out-of-specification for camber on either side, proceed with Step 3.
3. Obtain rear camber adjustment kit (E7DZ- 5K751-A).
4. Raise vehicle using frame hoist by supporting rear of vehicle forward of rear suspension tension strut, and allow suspension to hang in rebound position.
5. Remove stabilizer bar U-brackets from outboard ends of lower arms.
6. Remove parking brake cable attaching bracket from crossmember center bracket.
7. Place a floor jack with a block of wood under lower arm stamping midway between lower arm inner pivot bushing and lower arm coil spring.
8. Remove and throw away lower arm inner pivot attachment nut.
9. Using floor jack, pre-load underside of lower arm. Remove and throw away lower arm inner pivot bolt.
10. Using floor jack, slowly lower the arm out of crossmember pocket until coil spring is completely relaxed. A pry bar will be required to guide lower arm toward outboard direction to clear crossmember stamping as arm is being lowered.
11. Using a 1/2 inch diameter tapered rotary file, elongate both forward and rearward lower arm crossmember holes to the following dimensions:
Figure 6:
- If camber measurement from Step 2 was out-of-specification in the negative direction, elongate hole horizontally on inboard side until overall slot length measures 24 mm (0.94"), Figure 6.
- If camber measurement from Step 2 was out-of-specification in the positive direction, elongate hole horizontally on outboard side until overall slot length measures 16 mm (0.63"), Figure 6.
12. Using floor jack, raise lower arm back up into crossmember pocket.
Figure 6:
13. Install kit inner pivot cam bolt from front side of crossmember. As cam bolt is being installed, the two (2) kit tab washers are to be installed on bolt so that one (1) washer is trapped between each end of inner pivot bushing inner sleeve and inside surface of crossmember pocket, Figure 6.
14. Place kit cam washer and nut on bolt, position tab washers to be in contact with crossmember bracket, and tighten nut to about 50 ft.lbs. (68 N-m), Figure 6.
15. Repeat Steps 7 through 14, for opposite side of vehicle.
16. Reinstall stabilizer bar U-brackets and parking brake cable bracket.
17. Remove vehicle from hoist and place on alignment rack.
18. Reset rear toe to nominal specification of +0.06~ toe-in for each individual wheel.
19. Loosen lower arm pivot nut approximately one
(1) turn.
20. Adjust camber to -0.7~ by rotating cam bolt.
NOTE: Rim of cams will ride against ribs which are formed in crossmember bracket. The cam is not intended to be turned a full 360~.
21. Hold cam bolt head in position with a back-up wrench and tighten inner pivot nut to specification (40-60 ft.lbs./54-81 N-m) Take care not to disturb cam/alignment setting while tightening.
