Issue: Some 1998 MY vehicles within the above VIN ranges may have outer fulcrum bolts of the incorrect specification in the rear suspension. The fulcrum bolts connect the rear hub carriers to the outer ends of the rear suspension wishbones. Action: Install replacement fulcrum bolts on all 1998 MY vehicles within the above VIN ranges. If possible perform this action while the vehicle is undergoing PDI or prior to delivery to the customer. In the case of vehicles already in service, perform the action at the first service opportunity or next dealer visit. FULCRUM BOLT REPLACEMENT PROCEDURE 1. Raise the vehicle on a lift so that the rear suspension arms are supported while still allowing access to the nut (Illustration 1) and also to the head of the fulcrum bolt (Illustration 2). 2. Remove the rear road wheels. 3. If necessary, clean the head of each fulcrum bolt so as to be able to identify the marker line stamped on the head of each bolt (Illustration 2). Use a fine-pointed scriber to mark on each wishbone the location of the marker line, prior to dismantling. The marker line will not necessarily be in the location illustrated, depending on previous adjustment to effect correct wheel alignment. SCRIBING POSITION OF BOLT HEAD (LEFT SIDE SHOWN) ILLUSTRATION 2 4. Remove the retaining nut from the fulcrum bolt on one side of the vehicle and retain the washer for reuse. 5. Supporting the hub carrier in position and use a short drift approximately 14 mm. in diameter to drive out the fulcrum bolt toward the rear. Discard the bolt and nut. 6. While still supporting the hub carrier in position, install the replacement bolt from the rear. Rotate the bolt as necessary to allow the eccentric head of the bolt to fully seat in the guide slot in the wishbone. Align the marker line on the head of the bolt with the line previously scribed on the wishbone in step 3. Install the washer with a new self-locking nut, and tighten until the bolt begins to grip, ensuring that the marker line on the bolt head remains aligned to the scribed line. 7. Repeat 5 & 6 above on the opposite side of the vehicle. 8. Reinstall the wheels and lower the rear of the vehicle to the lift platform or workshop floor, as appropriate for the following operations. Check that the road wheel nuts are fully tightened. 9. Check the level of fuel in the tank. If full, no adjustment is required. If partly full, place in the luggage compartment, as near to the fuel tank as possible, weights equivalent to the amount of fuel which would be required to fill the tank to full condition. Allow 8 lbs. for each gallon which would be required to bring the tank to full. Allow 0.8 kg for each liter of fuel. Any luggage in the luggage compartment or in the passenger compartment should temporarily be removed, so that the vehicle is at the specified weight condition for a rear wheel alignment check.

SUBJECT: Fuel Odor or Spotting on Ground – Replace Fuel Pump Module MODELS: 2006 Chevrolet Cobalt 2006 Pontiac Pursuit 2006 Saturn ION Originally Sold or Currently Registered in Arizona, Nevada 2007 Chevrolet Cobalt 2007 Pontiac G5 2007 Saturn ION Originally Sold or Currently Registered in Arizona, California, Florida, Nevada, Texas This bulletin is being revised to include additional population. Please discard all copies of bulletin 09226, issued January 2010. CONDITION General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 2006 model year Chevrolet Cobalt, Pontiac Pursuit, and Saturn ION vehicles originally sold, or currently registered, in Arizona and Nevada; and 2007 Chevrolet Cobalt, Pontiac G5, Saturn ION vehicles originally sold or currently registered in Arizona, California, Florida, Nevada, and Texas. Some of these vehicles have a condition in which the plastic supply or return port on the modular reservoir assembly (MRA) may crack. If either of these ports develop a crack, fuel will leak from the area. The customer may notice a fuel odor while the vehicle is being driven or after it is parked. If the crack becomes large enough, fuel may be observed dripping onto the ground and vehicle performance may be affected. If a sufficient amount of fuel were to leak out and if an ignition source were present, a vehicle fire could occur. CORRECTION Dealers/retailers are to inspect and, if necessary, replace the fuel pump module. VEHICLES INVOLVED Involved are certain 2006 model year Chevrolet Cobalt, Pontiac Pursuit, and Saturn ION vehicles originally sold or currently registered in Arizona and Nevada; and 2007 Chevrolet

2014 Chevrolet Silverado 1500 Dinghy or Flat Towing Procedure

Filed Under (Chevrolet) by admin on 25-07-2015

Some customers may want to tow their vehicle behind another vehicle with all four tires on the ground. This is referred to as flat, dinghy towing or even as a “toad” (slang for towed vehicle). Towing in this manner is acceptable only on certain 4WD trucks depending on the transfer case option. The vehicle should be properly equipped and prepared as described below. The information contained in this bulletin supplements the Owner’s Manual. Please provide a copy of this bulletin to customers that want to dinghy tow their truck. Towing Set Up Procedure Notice: Use extra care whenever towing another vehicle. Do not exceed the towing vehicle’s ratings such as the gross combination weight rating (GCWR) by adding the weight of the dinghy towed vehicle or vehicle damage may result. Recreational/Dinghy tow basic setup procedures Four wheel drive pick-ups with a two speed transfer case (that have a neutral and a 4 low position): 1. Tow only in forward direction. Position the vehicle to be towed behind the towing vehicle. 2. Securely attach the vehicle to the tow vehicle. 3. Firmly apply the parking brake, start the engine and shift the transmission to neutral.

1997 Ford Ranger Brakes Rear Drum Cleaning And Inspection

Inspection Use Rotunda Brake/Clutch/Service Vacuum 091-R0001 or equivalent to remove all dust from backing plates and interior of brake drums (1126). Wheel Cylinders 1. Rear wheel cylinders should not be disassembled unless they are leaking. Pull back each rear wheel cylinder dust boot and inspect for leakage. 2. Excessive brake fluid at this point indicates leakage past the piston cups and a need for rear wheel cylinder (2261) overhaul. A slight amount of fluid is nearly always present and acts as a lubricant for the pistons. If evidence of leakage is noted, the rear wheel cylinder should be disassembled, inspected and overhauled. 3. Inspect the rear wheel cylinder bore for scratches and pitting. If the rear wheel cylinder is pitted or has deep scratches, the rear wheel cylinder must be replaced. Brake Drums 1. A brake drum should be visually inspected and measured with Rotunda Brake Drum Micrometer 104- 00046 or equivalent. Before making an inspection or measurement, remove grease, brake fluid, or other contaminants from the brake drum using denatured alcohol. 2. Best shop practice requires measuring every brake drum with a brake drum micrometer regardless of visual inspection. The brake drum micrometer is set to the drum diameter and measures the amount and type of wear. Measure the diameter at various points 45-degrees apart around the brake shoe and lining contact area, and at the bottom of the deepest groove to determine if the brake drum requires replacement. Brake Lining 1. Inspect rear brake shoes and linings (2200) for excessive lining wear or shoe damage. If lining is damaged or worn within 0.79mm (1/32 inch) of the rivet heads on riveted linings, it must be replaced. Replace any rear brake shoe and lining that has been contaminated with oil, grease or brake fluid. Replace rear brake shoe and lining in axle sets only. Never replace just one rear brake shoe and lining of a brake assembly. Replace both primary and secondary shoes. Prior to replacement of lining, brake drum diameter should be checked to determine that brake drum diameter is within specification. If braking surface diameter exceeds specification, the brake drum must be replaced. 2. Check condition of rear brake shoes and linings, retracting spring, hold-down springs, and brake drum for signs of overheating. If rear brake shoe and lining metal parts have a slight blue coloring, indicating overheating, retracting and hold-down springs should be replaced. Overheated springs lose their tension and could allow new rear brake shoe and lining to drag and wear prematurely, if not replaced.
