Simple Maintenance

Out of sight, out of mind. Remember that old adage? Well, to help add miles or years to your vehicle's life, it is essential to be mindful of all your components.

Brake Caliper Slides

One of the most overlooked items on your vehicle. Proper maintenance of this simple component could be the solution to any of these brake symptoms; brake pull when not applying the brakes, brakes overheating prematurely, or uneven brake wear. If the caliper slides are dirty, rusty or corroded, they could cause the caliper to "hang-up". Your 4x4 Quigley van could have either a round style covered with a rubber foot (late models), or a steel covered rubber spring style (early models).

Round Style

The caliper should move easily by hand left and right (in or out). If not, inspect the slide by removing it. You can either clean or completely replace your slides. To clean slides, either sand or polish them until they move freely left or right (in or out) by hand when mounted. Cover the slides with a light coat of antisieze or lithium grease. DO NOT apply too much! You do not want grease on your brakes. If the slide's boot is torn, then you want to replace the slide, because it is no longer protecting the slide from the elements.

Steel Covered Rubber Spring Style

This type of slide mounts between two flat surfaces -- one on the caliper and the other on the caliper mount. As with the round style, the caliper should move easily left and right (in or out) by hand when mounted. If not, remove the spring slide and inspect it, as well as both mounting surfaces. Clean surfaces until they are shiny. Apply either a light coat of antiseize or lithium grease to both mounting surfaces. If done correctly, you should be able to install spring slides with the palm of your hand, and check that the caliper moves easily left and right (in and out).

Checking Fluids

Your OEM Owner's Manual has instructions for when to check and change your fluids. For your 4x4 related fluids, refer to our maintenance schedules.

Ford Maintenance Schedules GM Maintenance Schedules Nissan Maintenance Schedules

Check Engine Oil

Simple enough, use your vehicle's dipstick to verify a safe level of oil. Do not overfill. Follow your vehicle's "Owner's Manual" for maintenance schedule and proper engine oil.

Transmission Fluid

Your automatic transmission will have a dipstick similar to your engine oil. Dipstick has both a hot and cold level gauge, more accurate to check when the fluid is hot. Follow your "Owner's Manual" for maintenance schedule and proper transmission fluid.

Transfer Case

Your transfer case will have two plugs, the upper plug is your fill plug. The GM requires an 18mm wrench or socket while the Ford uses a 10mm alien head. Check your fluid level by removing the FILL PLUG , fluid should trickle out of the plug. Use automatic transmission fluid (ATF). 

Choose the correct style of Quigley 4x4 system when referring to the maintenance schedules.

GM IFS Front Differential

Again, this component will have 2 plugs. The lowest towards the ground is the Drain Plug, and the highest is the Fill Plug. The procedure to check your fluid level is the same as the transfer case: use a 15mm wrench or socket to remove the Fill Plug. Fluid should trickle out of the plug. Use 80-90w gear oil fluid.

Questions? Refer to the GM Maintenance Schedule

Solid Axle Differential

With a 3/8 ratchet, remove the fill plug. Fluid should trickle out of the plug opening. Use 80-90w gear oil.


Grease all "greasable" zerk components. Refer to the proper maintenance schedule.

Other Fluids

All other fluids, such as brake, coolant, windshield washer fluids, etc., refer to your vehicle's OEM for proper fluid types and maintenance schedule.

We recommend before a long trip that you take the time to check ALL your fluids. You are looking for proper operating levels as well as condition of the fluids. You should be looking for burnt color, excessively dark coloration, or discoloration.

Caution: Always check you fluids after operating vehicle in water. Fluid will have a foamy, milky discoloration when contaminated with water.
