NARSA To Again Hold Annual Convention At AAPEX
The International Heat Transfer Association (NARSA) will again hold its annual convention at Harrah’s Las Vegas during the Automotive Aftermarket Products Expo (AAPEX). AAPEX will be held Tuesday, Nov. 5 through Thursday, Nov. 7, at the Sands Expo Center in Las Vegas, Nev.
Wheel Speed Sensor Diagnostics for Meters and Scopes
There is no way to quickly tell if a Wheel Speed Sensor (WSS) is passive or active. Both sensors have two wires and are located in the same position on the vehicle. Often, the service information will not indicate what types of sensors are on the vehicle
Bearing Diagnostics: Brinelling and Non-Noise Failures
In the good old days, most serviceable wheel bearings were maintained at least every 25,000 to 30,000 miles during a brake job. During this process, races, stub-axles and cages could be inspected for damage and replaced if necessary. Today, the average life of a sealed wheel bearing or hub assembly is about 85,000 to 100,000 miles. But they can fail sooner than expected without a whisper.
Tech Tip: Measuring Wall Thickness of Main and Rod Bearings
Although the best method to measure clearance between the crankshaft and crankshaft bearings is by using a bore gauge while the bearing is installed in the cylinder block or connecting rod, the question of measuring wall thickness of the bearings to calculate the clearances still comes up from time to time.
Bosal Introduces New Innovative Tow Hitch Program
The ACPS (Automotive Carriers and Protection Systems) Division of Bosal North America, Inc. has announced the introduction of their innovative tow hitch program for the North American vehicle market. The new Bosal hitch has a very unique design that allows the vehicle owner to remove it when it is not use.
Wheel Bearings
Wheel bearings can be of either ball or tapered roller type. The ball bearings used for front wheel bearing applications are an angular type. An angular-type ball bearing will accept greater thrust loads than a Conrad-type bearing, which will accept a 100 percent load in the radial or thrust position and any combination of a 100 percent load. A tapered roller bearing will accept both a radial and a thrust load. All wheel bearings come in sets.
Tech Tip: Moly-Based Coating Conflicts
Using a Molybdenum Disulfide-based coating, such as a lubricating coating that is often used on camshafts, is an excellent way to increase load capacity and improve durability.
Alignment & Suspension Specs: Ford Escape 2001-2010
The Ford Escape is one of the longest running Ford platforms with models that remained unchanged mechanically from 2000 to 2010. While it is not the most complicated alignment, it does have some quirks that have emerged during its past 10 years of service.
Coni-Seal and DSPCon Prognostics to Revolutionize Automotive Maintenance with IntelligentParts Forecasting System
Coni-Seal and DSPCon Prognostics have teamed to announce an initiative focused on bringing peace of mind to drivers and their families. The IntelligentParts Forecasting System, a joint effort of both companies, embeds sophisticated technology into any type of moving vehicle. The technology can predict potential points of failure and notify drivers before a situation becomes worse.
Tech Feature: Steering Linkage Service
Although most technicians take steering linkages for granted, it pays to review the basics. Knowing them can prevent everything from excessive tire wear to the most serious situation – loss of driver control due to failure of this system.
