REMOVAL & INSTALLATION STEERING COLUMN Removal 1) Disconnect battery ground cable. Remove steering wheel. On Cressida, Corolla, MR2 and Tercel models, remove fuse box cover, lower instrument trim panel and air duct from under steering column. 2) On all models, remove upper and lower steering column covers. Remove combination switch. Mark position of “U” joints and shaft for reassembly. 3) On models with “U” joints, remove “U” joint retaining bolt. On models with flexible joint, remove flexible joint retaining bolt. NOTE: On 2WD Pickup models, remove steering column with intermediate shaft attached. 4) On all models, mark position of joint and pinion shaft for reassembly. Remove intermediate steering shaft. 5) Remove floor pan cover bolts. Remove tilt bracket-to- dashboard mounting bolts. Remove steering column toward inside of vehicle.

Fig. 3: Exploded View of Land Cruiser, Pickup, Van & 4Runner Steering Column Assembly Courtesy of Toyota Motor Sales, U.S.A., Inc. Installation 1) To install steering columns, reverse disassembly procedure. Grease main steering shaft and all bearings. 2) Ensure marks made to flexible couplings and to “U” joints are aligned. Ensure steering column and shafts do not bind after installation. STEERING COLUMN OVERHAUL NOTE: Camry, Corolla, MR2 and Tercel steering columns are similar. Some of the following procedures will not pertain to all models. Disassembly (Camry, Corolla, MR2 & Tercel) 1) Remove tension springs, grommets and screws from tilt bracket. Remove tilt lever left-hand set bolt. Remove column upper support lock bolt. 2) Remove tilt steering support bolts and pawl set bolts. Place bushings and “O” rings aside and keep them clean. Remove ignition lock cylinder. 3) Using a screwdriver, push 2 thrust stoppers into bearing retainers. Pull out shaft from column. Remove the No. 1 column ring, bearing retainer, thrust stoppers and No. 2 column ring from shaft. 4) Remove snap ring and lower bearing from shaft. Remove bearing inner snap ring. Remove upper bracket retaining bolts and ground strap. Separate upper bracket from column. Inspection 1) Check that steering lock mechanism operates properly. Check upper bearing for smooth rotation or excessive noise. Replace upper bearing (if necessary). 2) Using Drift (09631-00020) and Adapter (09627-30010), drive bearing from upper bracket. Pack new bearing with grease. Using the same drift and adapter used in removal, drive new bearing into upper bracket. 3) Inspect lower bearing for smooth rotation or excessive noise. If lower bearing shows signs of wear or damage, replace with a new one. Reassembly 1) Install upper bracket onto column. Install ground strap. Tighten retaining bolts to 14 ft. lbs. (19 N.m). Install inner snap ring on shaft groove nearest to center of shaft. 2) Install lower bearing and lower bearing snap ring. Place No. 2 column ring into position next to bearing on side nearest center of shaft. See Fig. 4.
Correction 1. Visually inspect the tires and the wheels. Inspect for evidence of the following conditions and correct as necessary: 2. Set the tire pressure to 30 psi (205 kPa) COLD. Subject: Shake/Vibration in Steering Wheel, Floor, Seat at Highway Speeds on Smooth Roads (Diagnose/Balance Tires/Wheels) Models: 1998-2005 Buick Park Avenue, Park Avenue Ultra 2000-2005 Buick LeSabre 1998-2004 Cadillac Seville (SLS, STS) 2000-2005 Cadillac DeVille (DTS only) 2001-2003 Oldsmobile Aurora 2000-2005 Pontiac Bonneville (17″ Tires only) • Missing balance weights • Bent rim flange • Irregular tire wear • Incomplete bead seating • Tire irregularities • Mud/ice build-up in wheel • Stones in the tire tread © 2009 General Motors Corporation. All rights reserved 3. Road test the vehicle with the Electronic Vibration Analyzer (EVA) essential tool for a sufficient distance on a known, smooth road surface to duplicate the condition. Record the Hertz (Hz) reading as displayed by the EVA onto the tire data worksheet found at the end of this bulletin. This should be done after a tire break-in period of at least 10 miles (16 km) at 45 mph (72 km/h) or greater, in order to eliminate any possible tire flat-spotting. 4. If the road test indicates a shake/vibration still exists, check the imbalance of each tire/wheel assembly on a known, calibrated, off-car dynamic balancer. If any assembly calls for more than ¼ ounce on either rim flange, remove all balance weights and rebalance to as close to zero as possible. Important: Some GM dealers may have a Hunter GSP9700 Road Force Balancer, or a Coats XR1850 Runout Balancer. Either will simplify Step 5 by not requiring dial indicators. If a Hunter GSP9700 machine is available, it may also be used to measure the radial force of the tire/wheel assembly. A guideline here is 18 lbs or less. 5. While on the balancer, measure wheel runout. If radial or lateral runout exceeds .020 in (0.50 mm) for aluminum wheels (.030 in (0.76 mm) for steel wheels), replace the wheel. 6. After confirming wheel balance and wheel runout, if any changes were made, road test the vehicle again. 7. If the smooth road shake/vibration still exists: Important: THE CONTROL ARMS SHOULD ONLY BE INSTALLED ON VEHICLES IF, AFTER THE TIRE AND WHEEL DIAGNOSIS AND REPAIRS HAVE BEEN PERFORMED, THE VIBRATION CONDITION STILL EXISTS. 8. Replace both lower control arms on vehicles built prior to the following VIN breakpoints. On Aurora, Bonneville, DeVille, Park Avenue, Park Avenue Ultra and Seville models, a newly developed hydro-bushing lower control arm with improved damping characteristics has been released. This control arm is not used on the LeSabre. The new lower control arms may provide an incremental improvement to the vehicle ride. Customers who have become “tuned in” to the shake condition may still feel some shake in the vehicle after the new lower control arms are installed. Refer to Lower Control Arm Replacement in SI (refer to the Parts Information table below for SI document ID numbers) . Important: The completed worksheet must be attached to the hard copy of the repair order. • If a Hunter GSP9700 Road Force/Balancing machine is used, record radial force variation (RFV) on the worksheet at the end of this bulletin. If one or more of the tire/wheel assemblies read more than 18 lbs, match mount the tire to the wheel to get below 18 lbs. Readings of 12 lbs or less are preferable for sensitive customers. • If a Coats XR1850 Runout/Balancing Machine is used, record radial runout of the tire/wheel assemblies on the worksheet at the end of this bulletin. If one or more of the tire/wheel assemblies are more than .040, match mount the tire to the wheel to get below .040. Readings of .030 inch or less are preferable for sensitive customers. • If the RFV or runout cannot be reduced to an acceptable level, replace the affected tire(s) under the guidelines of the GM Tire Warranty. • The screened tire program is only available for the General branded tires used on the Buick LeSabre. Complete the tire request form at the end of this bulletin and fax to Continental/General. • Road test the vehicle to ensure the shake/vibration has been eliminated

SYMPTOM A moan or whine is heard when turning the steering wheel when the engine is cold. There may be air bubbles or foam in the power steering reservoir. The noise usually goes away when the engine warms up. PROBABLE CAUSE Air enters the power steering pump through the inlet joint O-ring. CORRECTIVE ACTION Replace the O-ring on the power steering pump inlet joint. PARTS INFORMATION O-ring: P/N 91345-RDA-A01, H/C 8811010 REQUIRED MATERIALS Honda Genuine Power Steering Fluid: P/N 08206-9002, H/C 3747284 (One container repairs about 12 vehicles.)
