SERVICE EQUIPMENT
Because R-134a is not interchangeable with R-12, separate sets of hoses, manifold gauge set and recovery/recycling equipment are required to
service vehicles. This is necessary to avoid cross-contaminating and damaging system.
All equipment used to service systems using R-134a must meet SAE standard J1991. The service hoses on the manifold gauge set must have
manual (turn wheel) or automatic back-flow valves at the service port connector ends. This will prevent refrigerant from being released into
the atmosphere.
For identification purposes, R-134a service hoses must have a Black stripe along its length and be clearly labeled SAE J2196/R-134a. The low
pressure test hose is Blue with a Black stripe. The high pressure test hose is Red with a Black stripe, and the center test hose is Yellow with a
Black stripe.
R-134a manifold gauge sets can be identified by one or all of the following.
Labeled FOR USE WITH R-134a on set
Labeled HFC-134 or R-134a on gauge face
Light Blue color on gauge face
In addition, pressure/temperature scales on R-134a gauge sets are different from R-12 manifold gauge sets.
SYSTEM SERVICE VALVES
SCHRADER-TYPE VALVES
Schrader valve is similar in construction and operation to a tire valve. When a test gauge hose with built-in valve core depressor is attached,
Schrader stem is pushed inward to the open position and allows system pressure to reach gauge.
If test hose does not have a built-in core depressor, an adapter must be used. Never attach hose or adapter to Schrader valve unless it is first
connected to manifold gauge set.
Refrigerant R-12 Schrader-type valve cores have TV5 thread size. Refrigerant R-134a Schrader-type valve cores use M6 (Metric) threads. R-
134a valve cores can be easily identified by use of "O" rings and external spring. See Fig. 1
.
SERVICE VALVE LOCATIONS
SERVICE VALVE LOCATIONS NOTE:Synthetic/PAG oils absorb m oisture very rapidly, 2.3-5.6% by weight, as com pared to a m ineral oil
absorption rate of .005% by weight.
NOTE:Refrigerant R-12 service hoses will ONLY be labeled SAE J2196.
NOTE:Although sim ilar in construction and operation to a tire valve, NEVER replace a Schrader-type valve
with a tire valve.

1. With steering gear removed from vehicle, place steering gear in a soft-jawed vise. Mark threaded portion of tie rod for reassembly.
Remove tie rod ends. Remove tie rod boots. Remove lock pins from both ends of rack. See Fig. 1
.
2. Remove tie rod ball socket from end of rack. Remove both tie rods. Remove lock nut from yoke plug. Remove yoke plug, spring and
yoke support. Use a small screwdriver to remove pinion oil seal from pinion shaft. Remove pinion bearing snap ring.
3. Remove pinion and bearing assembly. If necessary use Valve Body Puller (T78P-3504-B) to remove pinion and bearing assembly.
Remove rack from pinion side of housing. If lower pinion bearing needs replacing, use Blind Hole Bearing Puller (D80L-100-L) and
Slide Hammer (T50T-100-A) to remove.
4. Press bushing lock tabs into the 3 slots located at end of rack housing. Use Blind Hole Bearing Puller (D80L-100-L), to remove rack
support bushing from right end of rack housing.
Inspection
1. Check rubber boots, ball bearings and tooth surface of rack for wear or damage. Using a dial indicator and "V" blocks, check rack for
straightness. Maximum allowable runout is 0.012" (0.3 mm). If rack support bushings are worn, use a screwdriver to release the tab lock
on the side opposite the pinion. Use blind hole Bearing Puller (D80L-100R) with slide hammer to remove bushing.
2. Check tie rod ball joints for smooth operation. Replace parts as necessary. Check sliding surface of rack support and gear housing for
cracks or damage. Check rack bushing for excessive wear. Replace entire gear housing assembly if any of these parts are worn or
damaged.
Reassembly
1. Apply lithium grease to ball bearing, roller bearing, inside of gear housing, lip of oil seal, sliding surface and back of rack support,
sliding surface of rack bushing, rack pinion teeth and ball joints. Install rack support bushing into right end of rack housing. Ensure lock
tabs engage with slots in housing.
2. If previously removed, install a new lower pinion bearing using a bushing installer or a piece of wooden dowel stock. Carefully insert
non-toothed side of rack into left end of rack housing, with rack teeth facing pinion bore. Position rack in housing so rack protrudes
2.4" (62 mm) from the left side of housing. Install pinion and upper bearing assembly so that when bearing is seated, notch (for "U" joint
clamp bolt) in pinion splines forms a 35-55 degree angle with the centerline of the housing. See Fig. 2
.

3. Install snap ring and spacer, with beveled side of snap ring facing upward (toward oil seal). Install oil seal spacer with tab side down,
locating tab in snap ring gap. Protect pinion shaft splines with tape. Coat tape with a thin coat of grease and install new seal. Using a soft
hammer, tap lightly on seal until it is flush with end surface of housing. Remove protective tape.
4. Mount rack in a soft-jawed vise and install new lock tabs and tie rods. Tighten tie rod with a "crows foot" wrench to 44-58 ft. lbs. (59-
78 N.m). Use a center punch to stake lock tabs washer in 2 places. Slide tie rod boot over tie rod and position on rack. Secure with
mechanic's tie wire. Install other boot and other boot clamps.
5. Center rack so that tie rods are equally extended. Grease rack support yoke. Install rack support yoke, spacer and spring in housing.
Apply sealer to adjusting cover (yoke plug) threads and install in housing. Install adjusting bolt and lock nut.
6. Tighten adjusting cover to 80-97 INCH lbs. (9-11 N.m). Slowly cycle rack back and forth 5 times through 90 percent of its full stroke.
Center rack so tie rods are equally extended. Loosen adjusting cover and retighten to 22-30 INCH lbs. (2.5-3.4 N.m). Using a spring pull
scale, measure force needed to turn pinion 180 degrees from center rack position.
7. Adjust pinion to position where most force was needed to turn it. Tighten adjusting cover to 48 INCH lbs. (5.4 N.m), then back off 5-10
degrees. Hold adjusting bolt with a wrench and tighten the lock nut with a "crows foot" to 29-36 ft. lbs. (39-49 N.m). 8) To comp l et e
reassembly, reverse disassembly procedure. Install tie rod ends and jam nuts. Ensure index marks align. See Fig. 1
. CAUT ION: If rack is taken out of wrong side, dam age m ay result to rack bushing.
NOTE:If fit between housing and bearing is too tight, strike outer ring of bearing lightly while checking
m esh of rack and pinion.

Inspection
Thoroughly clean all parts in solvent. Check bearings, hub, knuckle and rotor dust shield for excessive wear or damage. If new bearing is being
installed, check bearing preload. See BEARING PRELOAD.
Bearing Preload
1. To check and adjust preload, Spacer Selector Set (T87C-1104-B) must be used. Prior to assembling hub/rotor assembly into steering
knuckle, install spacer selector into steering knuckle and clamp tool in vise. Tighten center bolt, in increments, to 36, 72, 108 and
finally 145 ft. lbs. (49, 98, 147 and 196 N.m). Each time center bolt is tightened, seat the bearings by rotating steering knuckle by hand.
2. Remove steering knuckle from vise. Reinstall steering knuckle in vise, clamping it where shock absorber mounts. Using an INCH lb.
torque wrench, measure torque required to turn center bolt. Ensure torque reading is taken just as wrench starts to rotate.
3. Spacer thickness is correct if torque wrench indicates 2.21-10.44 INCH lbs. (.25-1.8 N.m). If measurement indicates less than 2.21
INCH lbs. (.25 N.m), a thinner spacer must be installed. If measurement indicates more than 15.93 INCH lbs. (1.8 N.m), a thicker spacer
must be installed.
4. Bearing spacers are available in 21 thicknesses, in .0016" (.040 mm) increments. Spacer No. 1 is thinnest and No. 21 is thickest. See
PRELOAD SPACER AVAILABILITY table. Changing spacer thickness one increment will change bearing preload 1.7-3.5 INCH lbs.
(.2-.4 N.m). Ensure correct spacer is installed and preload is within specification. Remove spacer selector set.
PRELOAD SPACER AVAILABILITY NOTE:Rem oval of press-fitted dust shield from steering knuckle is not part of norm al bearing service. Dust
shield should not be rem oved from steering knuckle unless it is being replaced.
