Diagnosing your Ford F-150 (2004-2008) with an OBDII scanner can reveal a range of engine and system issues, but sometimes, the problem is purely mechanical. A common culprit for noise and handling issues is a worn-out front wheel bearing. While you might think of heading straight to a mechanic, replacing wheel bearings at home is achievable with the right tools and a bit of know-how. This guide will walk you through using the Harbor Freight Front Wheel Drive Bearing Remover and Installer Kit, a budget-friendly option for DIY car repairs. This tool can save you significant money and give you the satisfaction of handling the job yourself.
First things first, while this guide focuses on the mechanical repair, it’s worth noting that understanding your vehicle’s overall health often starts with diagnostics. Although we’re not diving into OBDII scanner functionalities here, tools like OBDII scanners are crucial for modern vehicle maintenance to identify electronic faults. However, for issues like noisy wheel bearings, a hands-on approach with tools like the Harbor Freight kit is essential.
Before we get started, gather your tools. Alongside the Harbor Freight kit, you’ll need a few other items to ensure a smooth wheel bearing replacement.
Tools You’ll Need
- Harbor Freight Front Wheel Drive Bearing Remover and Installer Kit: (Search for “Front Wheel Drive Bearing Remover and Installer Kit” on Harbor Freight, as part number 66829 might be obsolete). Ensure you have the updated kit, identifiable by its black oxide coating and a one-piece forcing bolt.
- 1/2″ Ratchet: For applying torque.
- 36mm Socket: Commonly used for axle nuts.
- Jack Handle or Cheater Bar: For extra leverage when needed.
- Extreme-Pressure Moly Grease (or any grease): To lubricate tool threads and bearing surfaces.
- Vice Grips: To hold the bolt head if it spins during installation.
- Towel: To protect the bolt head from the vice grips.
- Sockets (various sizes): To fit the tool’s nut and potentially the bolt head if you don’t have vice grips.
- Wooden Blocks: To support the knuckle during hub removal.
- Hammer or 5lb Dumbbell (optional): For initial hub removal if it’s stuck.
- Dremel and Chisel/Screwdriver (optional): For separating the inner bearing race from the hub if necessary.
- Circlip pliers: To remove and install the bearing circlip (if applicable to your vehicle – ensure to check your F-150’s specifications).
Now that you have everything ready, let’s get into the step-by-step process of replacing your front wheel bearings using the Harbor Freight kit.
Step-by-Step Guide to Front Wheel Bearing Replacement
This guide assumes the wheel and brake components have already been removed, exposing the wheel hub and knuckle.
Hub Removal
If your hub is still tightly pressed in, you might need to loosen it before using the Harbor Freight tool. A common method is to use a socket and hammer to knock it out from the backside.
Place the knuckle securely on wooden blocks, ensuring the hub is facing downwards and has space to move. Position a socket on the back of the hub and use a hammer or soft-faced mallet to carefully drive the hub outwards. Once it starts moving, it should come out relatively easily. Be aware that one of the bearing races might come out attached to the hub; we will address this later.

Bearing Removal
Before you start pressing out the bearing, ensure you have removed the circlip that retains the bearing in the knuckle. This circlip can be quite stubborn and is essential to remove before attempting bearing removal.
Now, set up the Harbor Freight tool for bearing removal. Select the appropriate sized discs from the kit. Place the largest disc on the backside of the knuckle that will provide support without interfering with the knuckle itself. Position the receiving cup on the front side of the knuckle to receive the old bearing. Insert the forcing screw through the assembly.

Grease the threads of the forcing screw and the nut. Using your ratchet (and cheater bar if necessary), slowly tighten the nut, pressing the old bearing out of the knuckle. Ensure the tool remains aligned during the process.

Bearing Install
With the old bearing removed, it’s time to install the new one. It’s crucial to press only on the outer race of the new bearing to avoid damaging it. Select the appropriate discs from the Harbor Freight kit to ensure you are pressing on the outer race only. The inner race of the bearing protrudes further than the outer race, and pressing on it can lead to premature bearing failure.
Set up the tool with the discs positioned to press the new bearing squarely into the knuckle. Grease the outside of the new bearing and the inside of the knuckle with a thin layer of grease to ease installation. Also, grease the forcing screw, nut, and washer.

Tighten the nut slowly and steadily, pressing the new bearing into the knuckle until it is fully seated. You might need to use vice grips to hold the bolt head if it starts to spin. Be patient, as this process can take some time.

Don’t forget to reinstall the circlip after the new bearing is in place to secure it in the knuckle.
Hub & Inner Race Separation (If Necessary)
If the inner race of the old bearing remained stuck on the hub, you’ll need to remove it. A common technique involves using a Dremel to carefully cut a groove across the race at a shallow angle. Once you’ve almost cut through, use a chisel or flat-blade screwdriver and hammer to strike the groove. This should crack the race, allowing it to be easily removed from the hub. Alternatively, specialized bearing separators can be used if you have access to them.
Hub Install
Finally, it’s time to press the hub back into the new bearing. Set up the Harbor Freight tool again, ensuring you are pressing only on the inner race of the bearing this time. Pressing on the outer race during hub installation can damage the new bearing.
