Proper maintenance of your Bronco is essential to making your OBS truck last longer. Follow along as we discuss regular maintenance tips and things you can do to keep your 1992-1996 Bronco on the road for many years to come!
There are a number of areas that require regular maintenance to allow your OBS Bronco to perform at its best. At this point, these OBS trucks are over 30+ years old, and many have continued to rack up the miles. Oil changes are one of the most frequent serviceable areas on your Bronco. The general service interval for oil and oil filter changes is every 3,000 miles. The types of fluids and capacities to use can be seen in depth in our 1992-1996 Bronco Fluid Capacities article. LMR offers full oil change kits to make this service as easy as possible!
Also after many miles of drive time, spark plugs will corrode. This can cause misfires and rough idle. Restore the performance of your 1992-1996 Ford Bronco engine with a factory replacement spark plug kit! Don’t stop there, be sure to also swap out those old, cracked, and dry-rotted spark plug wires with a new set of plug wires.
Checking out your serpentine belt for damage and tension is always a good measure. A defective drive belt can cause power loss and premature accessory failure. Our belt offering includes belts from top brands such as Gates, which utilizes advanced technology that meets or exceeds the OE size, construction, and materials.
A majority of the common service areas on your Bronco are for the engine and drivetrain. However, it is recommended to also inspect your suspension. Including the shocks, struts, and steering components. You will want to keep an eye out for any leaks, broken/worn areas, or noises made from these items, as this will typically indicate the item needs replaced or serviced. Bushings are one of the most common suspension components to wear out as well. This includes body mount bushings, sway bar, and leaf spring bushings.
After repairing or upgrading your suspension and steering components, a wheel alignment will be a must. Tires are also an important area to maintain. It is good practice to rotate your tires per the manufacturer's specifications to extend their life and ensure proper wear patterns. Maintaining the proper tire PSI is important in this step for the correct treadwear as well.
Beyond the mechanical upkeep, regular washing and care of your Ford Bronco can go a long way, especially if yours sees offroad use. A major issue these OBS trucks face is rust. Common rust areas, such as the lower portion of the tailgate, fender and rear wheel lips, lower rear quarter panels, or floor pans, can be relatively easily repaired with patch panels. Routine cleaning inside and out can help with rust prevention and prolong the interior materials, such as seat upholstery and other areas, even further.

Over time, your differential fluid can become used up or contaminated. This can cause your gears to lock up, causing poor performance and a whining noise. Changing this fluid and gasket is also a straightforward process you will want to maintain. Fortunately, we offer a complete front and rear differential service kit made to alleviate any of those problems with an all-in-one solution!
Proper maintenance for your transfer case is often overlooked; if it is not maintained to OEM specs, performance and reliability can suffer. Routine fluid changes should be performed at intervals stated within your owner's manual or manufacturer's specifications. A service kit is a quick and easy way to refresh any burnt or aged fluid within your transfer case. Extend the longevity of your transfer case in your OBS Ford Truck with Motorcraft's fluid kit!
Keeping your transmission fluid clean and cool, is another vital drivetrain area to prolonging your transmission life expectancy. Routine transmission maintenance should include fluid change, as well as a new filter, every 30,000 miles. This Motorcraft E4OD transmission service kit replaces your clogged filter with a new filter to ensure no harmful debris will be swimming around the new fluid.
Keeping an eye out for leaking lines, worn or noisy brake pads, and rotors is vital to maintaining the brake system in your full size Ford Bronco. Throughout the years, the factory rubber brake lines dry rot and crack, leading to fluid leaks and a soft pedal feel. Flushing out the brake fluid every couple of years or as needed is also just as important. Replace any leaking hoses, brake pads and rotors, fluid and any other brake components for your OBS truck from our wide selection of brake parts!
Maintaining your 1992-1996 Ford Bronco doesn’t have to be a daunting task, but it does require dedication and attention to detail. By staying on top of routine maintenance like oil changes, brake inspections, fluid changes, and suspension checks, you can ensure your Bronco stays reliable and continues to provide excellent performance for years to come. With the right care and the right parts, your OBS Bronco can remain a solid and trustworthy companion, whether you’re hitting the road or venturing off the beaten path. Regular upkeep is key to keeping this iconic OBS truck in top shape.
