Ford CF6000 Wheel Bearing Replacement Guide (1986-1990)
Keep your medium-duty work truck safe and on the road by understanding its wheel bearings.
- A failing wheel bearing on a CF6000 is a critical safety issue; do not drive on a suspected bad bearing.
- Always use premium aftermarket brands like Timken or SKF for this application; Timken is often preferred for heavy-duty trucks.
- Replacement is not a DIY job and requires professional installation with specialized tools like a hydraulic press.
- Bearings must be manually packed with high-temperature grease, and it is best practice to replace them in pairs.
Is Your Ford CF6000 Showing Signs of a Bad Wheel Bearing?
A failing wheel bearing on a heavy truck is a serious safety issue that should be addressed immediately. Because the CF6000 uses serviceable, non-sealed bearings, symptoms often appear gradually. Ignoring them can lead to wheel separation.
Common symptoms include:
- Grinding or Growling Noise: A constant humming, grinding, or growling sound from the wheel area that changes with speed is the most common sign.
- Wobble or Looseness: You might feel a vibration in the steering wheel or notice the wheel feels loose if you try to shake it when jacked up.
- Pulling to One Side: A badly worn bearing can cause the truck to pull to the left or right.
- Abnormal Tire Wear: Uneven wear on the inside or outside edge of a tire can point to a bad bearing causing improper wheel alignment.
Safety First: Do Not Drive with a Bad Wheel Bearing
A failed wheel bearing on a medium-duty truck can lead to a wheel locking up or detaching from the axle. This is a critical safety failure that could cause a complete loss of control. If you suspect a bad bearing, have the vehicle inspected immediately.
Choosing the Right Aftermarket Wheel Bearing
For a 1986-1990 Ford CF6000, original equipment (OEM) Ford parts may be difficult to find or discontinued. The aftermarket offers high-quality alternatives that often meet or exceed original specifications. For a critical part like a wheel bearing on a commercial vehicle, it is essential to choose a premium brand.
Brand Tiers: SKF vs. Timken
Both SKF and Timken are top-tier bearing manufacturers trusted in the heavy-duty industry. You cannot go wrong with either, but they have different reputations.
- Timken: Timken is highly regarded for its tapered roller bearings and has a very strong reputation in heavy-duty and commercial truck applications. Many truck owners and mechanics prefer Timken for its proven durability under heavy loads. Given the CF6000's role as a work truck, Timken is an excellent choice.
- SKF: SKF is another premium brand known for precision engineering and quality. While sometimes more associated with high-speed applications, SKF produces excellent heavy-duty bearings and is a trusted OEM supplier for many manufacturers. It is a reliable and high-quality option.
Pro Tip: For a commercial truck like the CF6000, the small price difference between a budget bearing and a premium one from Timken or SKF is negligible compared to the cost of downtime or a catastrophic failure. Always choose the best quality available.
Estimated Replacement Costs
The bearings for a CF6000 are not sealed hub assemblies. You will need to buy inner and outer bearings, as well as new races and seals for each wheel being serviced. The replacement process requires specialized tools, including a hydraulic press to remove the old races and install the new ones, making it a job for a professional shop.
| Part/Service | Estimated Cost (Per Wheel) |
|---|---|
| Aftermarket Wheel Bearing Kit (Inner/Outer Bearings, Races, Seal) | $47.46 - $81.99 |
| Shop Labor | $225 - $450 |
| Total Estimated Cost | $272 - $532 |
Cost estimates are for one side and do not include taxes, shop supplies, or potential costs for replacing a damaged spindle or hub. Labor costs are based on an estimated 1.5-3 hours at a typical commercial truck shop rate.
Frequently Asked Questions (FAQ)
Should I replace wheel bearings in pairs?
Yes, it is highly recommended. If the bearing on one side has failed due to mileage, the other side has been subjected to the same conditions and is likely near the end of its service life. Replacing both at the same time saves you from a second repair bill in the near future.
Do these bearings need to be packed with grease?
Absolutely. Unlike modern sealed hub assemblies, the tapered roller bearings on a CF6000 must be manually packed with high-temperature wheel bearing grease before installation. The hub itself should also have grease applied. Failure to properly pack the bearings will cause them to fail very quickly.
Can I replace a CF6000 wheel bearing myself?
This is not recommended for a DIY mechanic. The job requires lifting and securing a very heavy vehicle, removing large wheels and hubs, and using a hydraulic press to change the bearing races. Incorrect installation or improper torque on the spindle nut can lead to premature failure and is a major safety risk. This job is best left to a professional mechanic with experience in medium-duty trucks.
Are there any recalls for 1986-1990 CF6000 wheel bearings?
No, there are no specific recalls or Technical Service Bulletins (TSBs) from the NHTSA for wheel bearings on the 1986-1990 Ford CF6000. Any failures are typically due to normal wear and tear from age, mileage, and heavy use.
Technical Specifications
The 1986-1990 Ford CF6000 uses a serviceable wheel bearing setup consisting of separate inner and outer tapered roller bearings, corresponding races (cups), and a wheel seal. These components must be manually packed with a suitable high-temperature wheel bearing grease before installation.
