Hey, everyone. My name is Chris from Buy Auto Parts. I'm one of the salesmen there. Today, we're out of the office, it's Saturday morning, we're going to be doing the wheel hub of my 2004 Dodge Dakota. Right here are some of the tools we're going to need for the installation, removal. We're going to need a hammer. We're going to need a socket, a 13/16 or ¾” for the lug nut. We're going to need a ½” ratchet, a 3/8 ratchet, and we're going to need a couple of sockets. We're going to need a 1-7/16 half-inch. That's going to be for the locking nut for the hub assembly. We're going to need a ½” 13/16. That's going to be for the brake caliper mount. And we're going to need a 3/8 drive ... see here, that's a 9/16. That's going to be for the brake caliper to the mount. Of course, we're going to need a new hub assembly.
All right, cool. So today we're going to start with the hub assembly. For starters, you want to disable, remove all the brake components. So you're going to start with the actual caliper. We use a 3/8 ratchet, the one with the 9/16 wrench. We're going to remove all the hardware that holds the caliper on. As soon as we get all the hardware out that hold the brake caliper on, we're going to go ahead and remove the brake caliper, slide off. A little bit of work. Sometimes you need to use a screwdriver. All right. So we're going to go ahead and remove the brake caliper. With a screwdriver, with a little pry. It takes a little bit of work to get it off. You're not going to want to let it hang. It's very important to not put wear on the brake hose here. So you're going to set this up here. You can get it to balance, hook it on the shield or use a wire tie or a bungee cord to secure it. You just don't want to let it hang on the brake line. Then we'll remove the brake pads, put those back in later. Next, we're going to remove the brake caliper mount. It will require a half-inch ratchet, one with a 13/16 socket. There will be two mounting bolts. Loosen those up; sometimes they can be pretty stubborn when the vehicle has rust. Once you get both the bolts out, you're going to go ahead and remove the bracket. Set it aside. Next step, the rotor; it's just going to come right off. That leaves the hub assembly exposed. Next step, we're going to use the half-inch ratchet along with the 1-7/16 socket or 32 mm. Go ahead and break it loose. Sometimes you might need to use some lubricant like WD-40 or penetrating grease. Lubricate if there's a lot of rust. Next step is going to be removing the actual hub assembly.
So right now we're trying to remove the hub assembly. Depending on how bad it is and heat generated in the hub, it's going bad, it'd make it pretty tough to get it off the axle spindle. So it can take some work with either a puller or give it some love with the hammer to try to work it off. It's coming very slowly.
Right now, we're trying to remove this rusty hub in the Dodge Dakota. We're going to use a specially designed puller just for this. Attached to the lug studs using some of the lug nuts. We've got a 10-pound slack hammer here. It's going to help pull that hub off the spindle, just like that. So we'll go ahead and compare the new hubs here. We're going to do a quick match, make sure everything is good and the lug nuts are the same You're going to want to confirm with your vehicle prior to ordering the hub if you have two- or four-wheel ABS. It's very simple to do. Standard trucks come with two-wheel ABS, and the two wheels on the back are the ones with the ABS. So you'll have no electrical wires going to the front of the truck. If you need to determine this, you can lay under your truck and you want to look for any electrical wires going to the center section of the wheel if you have an electrical wire coming through here and a wire back here. You'll have a sensor and it's going to read a ring on the hub assembly called the reluctor ring. So this one, as you can see, does not have two-wheel ABS or it does not have four-wheel ABS. It's going to be a two-wheel ABS application. So you're going to confirm the front and the back of the hub are similar. There's no reluctor ring for the ABS to read. So now we're going to go and get this cleaned up and reinstall the hub. We're going to want to make sure that you replace the axle nut or the spindle nut. It's very important that this is replaced with a new one.
Now we're going to want to get this spindle cleaned up here. You're ready to reinstall our new hub. So we're going to get - wipe it down with a rag. Pick up some emery cloth which I'm going to use here to get some of that surface rust since this was so hard to get off. You're not going to want to use any kind of heavy sandpaper or anything, no power tools. You just want to kind of clean that surface rust off a bit; get ready for the reinstallation of the hub. Spray it off here with a cleaner and wipe it down. Make sure there's no debris along where the hub is going to be set against the spindle head here. It's very important spindle or hub won't properly seat. Now we're going to go ahead and reinstall the hub assembly. You see that went all the way down. You want to confirm its sitting flush at the back of the spindle so it spins nice and free. So now you're going to want to install your brand new spindle nut. We want to confirm this is a lock nut. It's got the polyurethane ring inside so you won't need to seal it. We're locked tight on that. We then reinstall the nut. We're going to have to tighten this down. After this, you're going to want to grab your torque wrench because this is going to be needed to be torqued with specific specifications of the vehicle. In order to determine that, it's best to either look in the manual or contact a local dealership to find out the correct specifications of torques like this. All right. So now we're going to go ahead and torque this to the specifications for the vehicle. We want to go ahead and set your torque wrench very important that this is tightened properly. That holds your wheel on the vehicle. I'm going to go ahead and tighten that down. Okay, properly torqued. It's nice and free and nice and smooth. And after the reinstallation of the brake rotor caliper mount, the brake caliper. We're good to go.
Okay, cool. So now we're going to do the reinstallation of everything here. Let's start with the brake rotor. Just slide it on. Next, the caliper bracket. You have two bolts. You want to make sure you use lock tight on these strips to make sure they don't back out at all. Put it on there. You don't need a ton of it, just a little bit. We're going to reinstall the bracket. Make sure both of those bolts are started. Go ahead and tighten them down. You're also going to want to tighten this to specifications with the manufacturer just like you did the center spindle nut. Next, we're going to go ahead and reassemble the brake caliper. That's installed. We're going to reinstall the front pad. Now we're going to reinstall our caliper. We're going to slide the caliper over. We'll take a little bit of hammer. We're going to use the 3/8th ratchet. And then we're going to go ahead and tighten these down, very important you go by manufacturer specs. And that's the full reinstallation of a hub assembly.
