- Raise and safely support the vehicle.
- Turn the steering wheel with a suitable spring gauge and check the reading.
- If the reading exceeds 3.3 lbs., adjust the steering gear as outlined in the following Steps.
- Place the front wheels in the straight ahead position.
- Loosen the rack screw locknut.
On 1988-91 Civic Si, perform the following procedure:
- Tighten, loosen and retighten the rack guide screw two times, to 3.6 ft. lbs. (5 Nm), then back it off 15°.
- Tighten the locknut on the rack guide screw to 49 ft. lbs. (68 Nm).
On 1988-91 CRX Si, perform the following procedure:
- Retighten the rack guide screw until it compresses the spring and seats against the rack guide.
- Back off the rack guide screw 15° and install the locknut on the rack guide screw. Tighten the locknut to 18 ft. lbs. (25 Nm).
On all other vehicles, perform the following procedure:
- Tighten the rack screw until it compresses the spring and seats against the rack guide.
- Back the rack guide screw off 40-60° and tighten the locknut on the rack guide screw to 18 ft. lbs. (25 Nm).
- Check for tight or loose steering through the complete turning travel.
- Recheck the steering effort.
- Lower the vehicle and with the wheels in the straight ahead position, measure the distance the steering wheel can be turned without moving the front wheels. The play should not exceed 0.4 in. (10mm). If it does, check all steering components.
REMOVAL & INSTALLATION
See Figures 4, 5 and 6
- Raise the vehicle and support it safely.
- Remove the cover panel and steering joint cover. Unbolt and separate the steering shaft at the coupling.
- Remove the front wheels.
- Remove the cotter pins and unscrew the castle nuts on the tie rod ends. Using a ball joint tool disconnect the tie rod ends. Lift the tie rod ends out of the steering knuckles.
- If equipped with manual transaxle, disconnect the shift lever torque rod from the clutch housing. Slide the pin retainer out of the way, drive out the spring pin and disconnect the shift rod.
- If equipped with an automatic transaxle, remove the shift cable guide from the floor and pull the shift cable down by hand.
- Remove the two nuts connecting the exhaust header pipe to the exhaust pipe and move the exhaust pipe out of the way.
- Push the rack all the way to the right and remove the brackets or mounting bolts. Slide the tie rod ends all the way to the right.
- Drop the rack far enough to permit the end of the pinion shaft to come out of the hole in the frame channel, then rotate it forward until the shaft is pointing rearward.
- Slide the rack to the right until the left tie rod clears the exhaust pipe, then drop it down and out of the vehicle to the left.
- Position the rack into the vehicle and tighten the mounting bolts to 29 ft. lbs. (40 Nm).
- Connect the exhaust pipe using a new gasket.
- Reconnect the shift linkage and adjust as required.
- Install the tie rod ends into the steering knuckle. Tighten the nuts to 32 ft. lbs. (44 Nm), then tighten as required to install a new cotter pin.
- Connect the steering shaft coupling and tighten the bolt to 22 ft. lbs. (30 Nm).
See Figures 7, 8, 9, 10 and 11Disassembly, Inspection and Assembly
- Remove the rack and pinion from the vehicle and support it in a bench vise.
- Loosen the band that retain the bellows on the ends of the rack and pull the bellows back.
- Unbend the lockwashers on the end of the tie rods.
- Using a 22mm wrench to hold the rack, remove the tie rods using a 17mm wrench.
- Remove the lock nut that retains the rack guide components and remove the pieces from the rack body. Be careful not to lose the spring.
- Remove the pinion assembly dust seal, then remove the 35mm snapring that retains the pinion assembly. Pull the pinion from the body.
- Slide the rack out of the gearbox body.
- Inspect the pinion assembly for wear, scoring or damaged teeth. If any of these are apparent the pinion must be replaced.
- Inspect the pinion bearing for freedom of movement and for signs of damaged balls in the bearing assembly. If the bearing is damaged, the entire pinion assembly must be replaced.
- Inspect the rack for signs of excessive wear or for damaged teeth. If the rack shows signs of damage, it must be replaced.
- Inspect the rack guide for scoring.
- Inspect the steering gear housing for signs of cracking, or damage to the pinion bore.
- Apply a thin coat of grease to the rack end bushing and install it in the housing by aligning the projections on the bushing with the hole in the housing.
- Apply a coating of grease to the rack and carefully slide it into the housing. Do this carefully to avoid damaging the surface of the rack.
- Install the pinion assembly into the housing and install the 35mm snapring to retain the pinion. Install the pinion dust seal.
- Coat the rack guide with grease and install the guide components into the housing. The rack guide screw will need to be adjusted after rack installation.
- Screw in each of the tie rods to the rack, while holding the lock washer so that its tabs are aligned with the slots in the rack. Install the stopper washer with the chamfered side facing out.
- Tighten the tie rod securely then bend the lockwasher back onto the flange.
- Install the bellows over the end of the rack housing and install the retaining clamp.
- Install the tie rod ends on the tie rods and fill the tie rod boots with grease.
- Install the rack into the vehicle and adjust the rack.
