Land Rover Air Ride Replacement

Land Rover was one of the first import nameplate manufacturers to adopt a four-corner air ride suspension on the Range Rover. Over the past 25 years, the system has become more refined and reliable.

Ride Of The Week: Oldsmobile Fournado

Never heard of the Oldsmobile Fournado? Then you probably missed the March 1968 issue of Super Stock & Drag Illustrated, which blurbed this car on its cover.

When Over-Voltages Electrocute PCMs

During the past nine months, I’ve had three instances of powertrain control module (PCM) failures on Jeep Wrangler vehicles that were evidently caused by an over-voltage condition.

Active Ride Control Diagnostics

In the 1990s, adjustable valve shocks and struts were all the rage. These systems had two or three comfort and sport settings that could be changed with buttons on the dash. These systems played the role of firming up the suspension if the driver wanted a sporty feel while driving. These systems have evolved to the point where they can actively change dampening characteristics in milliseconds.

Jeep Liberty Alignment Specs

The Liberty (2002-2007 KJ and 2008-2012 KK) was Jeep’s replacement for the Cherokee (XJ). The major changes from the Cherokee to the Liberty were an independent front suspension and trailing arm rear suspension. Compared to the Cherokee, the Liberty is actually easier to align.

Worn rocker arms and lifters should not be reused to prevent failures down the road. If you’re installing a new flat tappet cam, new lifters are a must. Any pushrods that are not straight must also be replaced, along with high-mileage valve springs that have weakened with age.

Tire Tread Wear: Causes And Symptoms

Tire tread wear can tell you a lot about a suspension. Most specifically, it can tell you if the angles, inflation and components are within specification. Here are the most common tread wear patterns and what causes them.

Timing Chain Replacement: Diagnosis And Repair

Timing chains, with their thinner width, reduce overall engine length and are more durable than timing belts, requiring no scheduled maintenance. Timing chains do make more noise, have higher weight and higher cost than timing belts, though.

Intermittent Engine Misfire Analysis

Even for an experienced diagnostic technician, ­attempting to diagnose an intermittent misfire ­condition that occurs only under specific driving conditions can be a frustrating exercise. Let’s begin by getting the basics out of the way. As we know, the general causes of a misfire fall under the ­general headings of 1.) ignition, 2.) fuel density, 3.) compression and 4.) timing failures.
