NOTE:
The Celica, Cressida and Supra steering columns are similar. Some of the following procedures will not pertain to all models.
- Pack new bearing with grease. Place bearing over intermediate shaft. Place intermediate shaft in a soft-jawed vise with bearing at "U" joint end of shaft.
- Using Sleeve (09612-22011 ) and Bearing Plates (09237-00010 ) and vise, drive new bearing onto shaft. Using a plastic hammer, tap the shaft toward the vise to drive the bearing onto the larger section of the shaft. Install snap ring.
- Using a press and Collar (09515-21010 ), press a NEW PPS sensor ring onto shaft with lettering facing away from "U" joint.
- Using the same drift and adapter used in removal, place upper bracket on block of wood and drive new bearing into upper bracket. Coat all moving, rubbing or sliding parts with grease.
- Use new "O" rings where needed. Install adjuster memory cover to upper bracket. Install pawl set bolt. Tighten pawl set bolt or nut (if equipped) to 14 ft. lbs. (19 N.m). See Figure.
- Install tilt lever and tilt control lever over the mounting pin. Use a bushing that will eliminate all play between tilt adjust lever, tilt control lever and the mounting pin.
- Bushings are available in sizes between .7087-.7100" (18.002-18.035 mm) in .0002" (.007 mm) increments. Install tilt steering pawl over pawl pivot pin. Aligning holes, install release pin.
- Install tilt lever retainer. Install retainer attaching nut and bolt. Tighten to 14 ft. lbs. (19 N.m). Using a drift and hammer, drive serrated bolt into tilt bracket. Check that bolt collar is firmly installed into pivot of control lever inside plate.
- Install nut onto serrated bolt. Tighten to 14 ft. lbs. (19 N.m). Select bushing for opposite side of tilt bracket that will eliminate all play. Bushings are available in sizes between .7089-.7100" (18.005-18.035 mm) in .0005" (.015 mm) increments.
- Select a shim or shims that will fit snugly between pivot points of upper bracket. Shims are available in sizes between .0067-.0728" (.17-1.85 mm) in increments of .011" (.30 mm).
- Install selected bushing and shim(s) into upper bracket pivot. Install bolt with a new nut. Tighten to 14 ft. lbs. (19 N.m). Install column cover support. Install stopper bolt and a new nut. Tighten to 96 INCH lbs. (11 N.m).
- Install 2 springs to side of tilt bracket. Install collar and spring over mainshaft. Turn ignition to "ACC" position. Insert mainshaft assembly into upper bracket.
- Using Steering Shaft Retainer (09950-20016 ), tighten steering mainshaft against the upper bracket. Take care not to overtighten steering shaft retainer. Install snap ring. Remove steering shaft retainer.
- Connect tilt bracket springs to cords. Install spring/cord assemblies into top of tilt bracket. Install dust seal to column. Install column tube to breakaway bracket. Tighten bolts to 14 lbs. (19 N.m).
- With thrust stoppers installed in the bearing retainers, place bearing retainers over lower bearing. Install No. 1 column ring over the 2 bearing retainer grooves to secure bearing retainers.
- Insert shaft into column. Align thrust stoppers with notches at bottom of column. Holding thrust stoppers in with a screwdriver, insert intermediate shaft into column until snap ring nearest center of shaft bottoms.
- Turn bearing retainers to seat thrust stoppers in column slots (if necessary). Connect main shaft-to-intermediate shaft "U" joint. Tighten attaching bolt to 19 ft. lbs (25 N.m).
- On Cressida and Supra, install steering sensor to bottom of column. Check that sensor does not touch sensor ring by turning steering shaft and listening for rubbing sound. Install sensor cover.
- On all models, check that tilt mechanism locks in all 8 positions. With mainshaft in neutral position, pull the tilt lever and check that the mainshaft rises to the uppermost position.
- Check for smooth operation of all shafts and "U" joints. Install combination switch, steering wheel, column covers and horn pad.
- Lubricate all moving parts with multipurpose grease before reassembly. Install pawl set bolt. Tighten pawl set bolt to 13 lbs. (18 N.m).
- Assemble tilt lever assembly. Select a bushing to eliminate all play. Bushings are available in sizes between .7086-.7100" (17.998-18.033 mm) in increments of .0003" (.007 mm).
- Install tilt pawl. Install tilt steering support-to-column bracket. Using a drift and hammer, drive in serrated bolt. Install shim and bolt to tilt pawl. Select a shim to eliminate all play.
- Shims are available in thicknesses between .0078-.0711" (.193-1.805 mm) in increments of .117" (.302 mm). Install column cover support. Install release pin to tilt pawl.
