RECOMMENDED PARTS REPLACEMENTS

KING PINS
	The king pin assembly should usually be replaced by a kit that contains the king pins, bushings, shims, thrust bearings, seals, gaskets, bolts, caps, and drawkeys for both sides of the axle. The average replacement interval for king pins is approximately 300,000 miles, or every 3 years.

	Reasons for replacement:
		Lack of lubrication Normal wear on bushings and bearings Salt and road contaminants that have entered the assembly Severe duty applications such as mining, construction, logging etc. Misalignment of seals, bearings, shims, bushings and drawkeys Out-of-round knuckle bore

ROD ENDS & DRAG LINKS
	Premature tire wear and excessive steering play are common symptoms of tie rod or drag link problems. Another symptom of failure for these parts can be seen when the tie rod and drag link joints “jump” when the steering wheel is turned on a stationary vehicle. The tie rod should be replaced more frequently than the drag link assembly. The average replacement interval of tie rod end is 240,000 miles. The average replacement interval of a drag link is approximately 300,000 miles.

	Reasons for replacement:
		Lack of lubrication Salt and road contaminants that have entered the assembly Excessive play Shock loads Leaking or cracked seals Misadjustment Excessive thread wear due to corrosion Boot cracks or tears

WHAT DOES MY TRUCK NEED?
	Air contains moisture, and when the temperature drops below the dewpoint, this moisture is released in the form of rain or fog. the same principle applies to a truck’s air system. Warm engine air passes through the air compressor and begins to cool and condense as it flows through the air lines. The moisture collects in the supply tank or “wet tank,” and should be purged daily to prevent system problems. In the long run, “preventive maintenance” through the use of the System Saver 1000 air dryer, with its specially designed Multi-Filter System, can help you save considerable time and money in the service bay.

	Reasons for having a truck air dryer:
		Protect valves and seals Remove dirt, oil, and other particulates from the air system Keep lubricants in the air lines Prevent equipment failure resulting from erosion Prevent system problems especially in cold climates Avoid costly downtime

AUTOMATIC SLACK ADJUSTERS
	Government Mandate National Transportation Safety Board (NTSB) studies have shown that vehicles equipped with automatic slack adjusters (ASAs) are less likely to have brakes that are out of adjustment. The Federal Government has mandated the use of automatic slack adjusters on all air-braked vehicles regulated by FMVSS 121, built on or after October 20, 1994.

	Reasons for having automatic slack adjusters:
		Keep brakes in constant adjustment Eliminate the need for frequent under-the-truck brake adjustments Reduce brake maintenance costs Reduce vehicle safety inspection citations Allow optimum brake performance

BRAKE LINING REPLACEMENT
	Replace the linings on both brakes of a single axle or all four brakes of a tandem axle at the same time. If you do not replace all the linings at the same time, poor brake performance may occur. Use only the same lining material with the same friction level across axles or on all four brakes of a tandem axle.

	Dirt is the number one cause of noisy brakes. To reduce dirt, always replace the S cam overhaul kit and install a new wheel bearing seal at every reline. This insures a new seal, preventing oil and dust build-up. Then, be sure to install backing plates on all wheel ends.
