Jeep Comanche Wheel Bearing Guide for 1986-1992 Models
Stop the humming and grinding—here's what you need to know about replacing your Comanche's wheel bearings.
- First, confirm if you have a 2WD model with serviceable bearings or a 4WD model with a sealed hub assembly; the parts are different.
- For longevity, especially if you off-road, spending more on a premium brand like Timken, SKF, or FAG is a worthwhile investment.
- Replacing 2WD front bearings is a manageable DIY job, but rear bearings require a hydraulic press and are best left to a professional shop.
- Always replace the bearing and race as a matched set and use high-temperature grease for disc brakes to prevent premature failure.
Understanding Your Comanche's Wheel Bearings
Before buying parts, you must identify your truck's setup. The 1986-1992 Jeep Comanche used two different front-end designs, and ordering the wrong part is a common mistake.
- 2WD Models: Most two-wheel-drive Comanches have serviceable wheel bearings in the front. This means you have an inner and an outer bearing that sit inside the brake rotor. These can be replaced individually along with their matching races. This guide focuses on these serviceable bearings.
- 4WD Models: Four-wheel-drive Comanches use a single, sealed wheel bearing and hub assembly. You cannot replace just the bearings in this unit; the entire assembly must be replaced.
- Rear Axles (All Models): The rear wheel bearings are pressed onto the axle shafts themselves. This is true for both 2WD and 4WD models. Replacing these requires specialized tools.
Pro Tip: Always replace wheel bearings and their races as a matched set. A new bearing will fail quickly if installed on an old, worn race.
Choosing the Right Aftermarket Wheel Bearing
Since genuine Mopar parts for this truck are largely unavailable, the aftermarket is your only option. Quality varies significantly between brands, so it's important to choose based on your budget and how you use your truck.
Brand Quality Tiers
- Premium Brands (Timken, SKF, FAG): These brands are widely regarded as the best in the industry, often meeting or exceeding original equipment (OE) quality. They use high-quality steel and precision manufacturing, making them the top choice for durability, especially if you use your Comanche for off-roading or heavy hauling. Owners and mechanics consistently recommend Timken and SKF for longevity.
- Mid-Grade Brands (National Bearing): National is a well-respected brand that offers a good balance of quality and affordability. They are a solid choice for a daily driver and are considered a reliable, no-frills option by many DIYers.
- Economy & Value Brands (Mevotech, WJB, Beck Arnley): These brands offer a lower price point, which can be appealing for budget-conscious repairs. WJB is sometimes noted as a decent value option. However, the long-term durability may not match that of premium brands. Mevotech is another value-oriented option.
- Brands to Approach with Caution (Crown Automotive): While Crown Automotive specializes in Jeep replacement parts, forum discussions among Jeep owners often report issues with poor fitment and lower quality on their various parts. While their bearings might be sourced from a reputable manufacturer, the brand's overall reputation makes it a riskier choice.
Known Issues, Recalls & Service Bulletins
Searches of the National Highway Traffic Safety Administration (NHTSA) database show no specific recalls or technical service bulletins (TSBs) for wheel bearings on the 1986-1992 Jeep Comanche. Failures are almost always due to normal wear from age and mileage, or accelerated wear from water, mud, and off-road use.
| Tier | Brands | Estimated Part Cost |
|---|---|---|
| Premium | Timken, SKF, FAG | $30 - $80 |
| Mid-Grade | National Bearing | $20 - $45 |
| Economy | WJB, Mevotech, Beck Arnley | $11 - $35 |
Note: Prices are for a single wheel's inner and outer bearing set. 4WD models require a complete hub assembly, which costs significantly more ($70 - $190+ per hub).
Frequently Asked Questions (FAQ)
Do I need special tools to replace my Comanche's wheel bearings?
For the 2WD front bearings, you will need standard hand tools, a torque wrench, wheel bearing grease, and a new cotter pin. For the rear axle bearings, you will need a hydraulic shop press to remove the old bearing from the axle shaft and install the new one. This is generally not considered a DIY job without access to a press.
Should I replace bearings on both sides at the same time?
It is highly recommended. If one wheel bearing has failed due to age and mileage, the other side is likely not far behind. Replacing them in pairs ensures balanced performance and prevents you from having to do the same job again in the near future.
What kind of grease should I use for the front bearings?
You must use a high-temperature wheel bearing grease. Look for a product specifically rated for disc brake applications, as the heat from the brakes can break down standard grease and cause the new bearings to fail.
Is a wheel alignment needed after replacing wheel bearings?
No, a wheel alignment is not typically required after replacing wheel bearings, as this repair does not affect the vehicle's alignment angles like caster, camber, or toe.
