Can you give some advice on idler arm repairs?

Sridhar’s Request: "Please discuss Idler arm repairs"

The idler arm is a pivoting support for the steering linkage, and is usually found on rear wheel drive cars and light trucks. Most front wheel drive vehicles use “rack & pinion” steering which does not require an idler arm. The idler arm consists of a bracket, an arm that connects the bracket to the center link of the steering linkage, and an internal pivot bearing. The purpose of the idler arm is to assist the pitman arm by supporting the steering linkage as it moves in the direction controlled by the steering gear. In other words, if yours breaks, you would have a very difficult time steering the car. (That’s bad). The good news is that they almost never break… but they do gradually wear out. The idler arm needs to be lubricated every time you have your oil and filter changed (every 3000 miles). Some common vehicle symptoms associated with a worn idler arm include wandering, tire edge wear, and loose or sloppy steering. The Idler arm should be closely inspected annually in conjunction with a front-end alignment.
