OVERHAUL
STEERING GEAR
Disassembly
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.

ST EERING SYST EM - POWER
1991-92 ST EERING Ford Motor Co. - Steering - Power Rack & Pinion
DESCRIPTION & OPERATION
Power steering system consists of a rack and pinion steering gear, valve body, power steering pump, fluid reservoir and interconnecting
hydraulic lines. Pressure and return lines from pump are connected to valve body. A vane-type power steering pump draws fluid from the
steering reservoir. Fluid is compressed by rotor and vanes inside steering pump and sent to steering gear. Pressure is monitored and controlled
by a pressure switch and a control valve located inside of steering pump.
TROUBLE SHOOTING
Refer to TROUBLE SHOOTING - BASIC PROCEDURES article in the GENERAL TROUBLE SHOOTING section.
LUBRICATION
CAPACITY
Information is not available.
FLUID TYPE
Use Dexron-II ATF type fluid.
FLUID LEVEL CHECK
Check fluid level before engine is started, while fluid is still cool. Remove reservoir cap fluid indicator on steering pump. Check fluid level.
Fluid should be between the "L" and "H" marks on the level gauge dipstick. If fluid is needed, fill to the "L" mark on dipstick. Run engine until
warm and turn steering wheel fully in both directions about 10 times. Return steering to straight-ahead position and shut engine off. Ensure
fluid level is between "L" and "H" marks. Add fluid if necessary.
HYDRAULIC FLUID BLEEDING
1. Raise and support front of vehicle. Ensure pump reservoir is filled to specified level. With ignition coil wire disconnected, crank engine
and add fluid to steering pump until fluid level remains constant. While cranking engine, rotate steering from stop to stop. Recheck and
add fluid as necessary.
2. Start engine and allow to idle for several minutes. Turn steering wheel completely lock-to-lock several times. Check fluid level. Add
fluid as necessary. Continue this procedure until there is no bubbling or decrease in fluid level.
ADJUSTMENTS
BELT TENSION
On Festiva, remove air duct and air cleaner. On all models, loosen steering pump mounting pivot bolt and the adjusting bolt lock nut. Using
Belt Tension Gauge (021-0028A), fit gauge to longest available belt span for testing. Adjust belt to specification. See BELT TENSION
SPECIFICATIONS . Tighten adjuster lock nut to 32-45 ft. lbs. (43-61 N.m) on Capri or 27-38 ft. lbs. (37-52 N.m) on Festiva.
BELT TENSION SPECIFICATIONS
REMOVAL & INSTALLATION
STEERING GEAR
Removal
1. Disconnect negative battery cable. On Capri, mark and loosen intermediate lower U-joint. On Festiva, mark and remove steering gear
intermediate shaft connecting steering gear to column shaft. On all models, disconnect high pressure and return lines and plug them.
Loosen front wheel lug nuts.
2. Raise vehicle. Remove front wheels. Remove tie rod end cotter pins and nuts. Separate tie rod ends from steering knuckles using Tie
Rod Remover (T85M-3395-A). Remove tie rod end splash shields. Remove right fender splash shield. Remove front catalytic converter
nuts and separate converter from inlet pipe.
3. Place reference marks on tie rod end and tie rod for reassembly reference. Loosen tie rod jam nut and remove right tie rod end. Remove
steering gear mounting bolts and washers. Slide steering gear to the left and pull right tie rod through fender opening. Remove steering
gear by sliding it to the right.
