2004 Buick LeSabre Shake/Vibration in Steering Wheel, Floor, Seat at Highway Speeds on Smooth Roads (Diagnose/Balance Tires/Wheels) Service Manual

download
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

1. Verify that the power steering pump reservoir is full. 2. Verify that the accessory drive belt is in good condition and that the pulleys are not bent or damaged. 3. Verify proper belt tension and operation of the belt tensioner. 4. Check for power steering hose ground out conditions. 5. Check for good engine idle and correct engine RPM. 6. Check to see that the rear transaxle mount does not have a plastic assembly aid installed which is used Subject: Steering Vibration/Shudder/Moan During Parking Maneuvers on Dry Pavement (Install Power Steering Pressure (Inlet) and/or Return (Outlet) Hose Assembly) Models: 1995-99 Buick Riviera 1997-2001 Buick Park Avenue, Ultra 2000-2001 Buick LeSabre 2000-2001 Pontiac Bonneville • 1995-98 Buick Riviera • 1997-98 Buick Park Avenue and Ultra • 1999 Buick Riviera • 1999-2001 Buick Park Avenue and Ultra • 2000-2001 Buick LeSabre • 2000-2001 Pontiac Bonneville • If fluid level is low, fill and check for leaks. • If power steering system has air in the system, perform the “Bleeding Air from Power Steering System” procedure as described in the Power Steering System sub-section of the Service Manual. Important: When performing the “Bleeding Air from Power Steering System” procedure, it is important that the front of the vehicle is supported by the lower control arms. If the vehicle is not supported by the lower control arms, the procedure may cause the strut bushing to dislocate and cause new concern. for assembly purposes. If the assembly aid is installed, remove the assembly aid and install the rear transaxle mount. 7. With the vehicle on dry pavement, maneuver the vehicle in parking positions. If the steering vibrates/shudders or moans in this test, replace the power steering pressure hose and/or the harmonic balancer. Important: A defective harmonic balancer on the 1995 Buick Riviera can influence steering vibrations after power steering hose installation. Important: When installing the pressure hose on the 1995 Buick Riviera, pull down on the pressure hose at the rear of the engine or bend the hose to allow clearance between the hose and the front of the dash.

REPAIR PROCEDURE: VALVE ROTATION: 1. Relieve the fuel pressure. Refer to the detailed service information available in TechCONNECTunder: Service Info>14-Fuel System>Fuel Delivery >Standard Procedure>Fuel System Pressure Release Procedure. 2. Remove upper intake manifold. Refer to the detailed service information available in TechCONNECTunder: Service Info >9-Engine>Manifolds>Intake Manifold> Removal. 3. Remove cylinder head cover(s). Refer to the detailed service information available in TechCONNECTunder: Service Info >9-Engine>Cylinder Head>Cylinder Head Cover(s) >Removal. 4. Remove rocker arm and shaft assembly. Refer to the detailed service information available in TechCONNECT under: Service Info >9-Engine>Cylinder Head> Rocker Arm/Adjuster Assembly >Removal). 5. Clean and mark the tip of each exhaust valve stem at the 12 O’clock position witha paint marker. The paint mark will be used later to assist with determining the amount of valve rotation. 6. Remove the sparkplugs. 7. Rotate the crankshaft clockwise, until the number 1 piston is at Top Dead Center (TDC) on the compression stroke. 8. Install the compression tester sparkplug adapter in cylinder#1 sparkplug hole. With air hose attached to sparkplug adapter, apply 620.5 to 689 kPa (90 to 100 psi) air pressure. This is to hold valves into place while servicing components. 9. Using Tool MD 998772A (1) with adapter 6527 (4) or equivalent, slightly compress the exhaust valve spring to release tension against the valve and valve spring retainer ( Fig. 1 ). 10. Remove the valve spring retainer locks and discard the locks. NOTE: It is important that the valve rotation section of this repair procedure be performed.
