How to Install a Wheel Seal and Grease a Wheel Bearing (2023)


Installing a front wheel seal in a ford truck or van isn't that difficult. In this video Ozzstar demonstrates how to remove the old seal and replace it with a new one. When the old seal is removed this is a good time to check the condition of the inner front wheel bearings and race. This also requires the bearing to be properly greased after inspection.

Hey welcome to the all-star scars channel, I'm glenn in today's fun project, I'm going to show you how to replace the wheel seal on the front, rotor or brake rotors of an ford e350.

This is a cargo van, a lot of the heavy duty or super duty fords like the f-250 f-350.

Have this set up um, even the older style f-150s have a hub at the back of the rotor.

Now this is a conventional rotor.

You usually think about on, like front-wheel drive cars and more modern vehicles where you don't have studs coming out, that's usually the telltale sign and in the center it's held on with a nut.

These you just kind of bang off the spindle or the hub and you're good to go so the old school.

What I'm going to show you here is that bearing the back bearing has a seal behind it, which holds the grease in so that those can stay lubricated.

Now the more modern vehicles that have this type of rotor, especially front-wheel, drive they're, going to just have a hub, that's already all built together and done.

That's your bearings in there and it's a little bit more difficult to service, but anyway, the video here is just to help you out how to remove that seal, inspect the bearing and then there's also a race, the bearing rides on the race, and if you have to take your rotor off, let's say to have it turned if you're not going to replace it, you get a go to a brake.

Lathe would do that that machine would turn it down, make it smooth.

So you don't have that wobble in it or warp.

Uh you'd have to take out that wheel seal on that bearing clean everything up before you can have that done all right.

So it's super simple to get that seal out.

You just need one of these seal pullers.

It's got this hook.

You could probably use a pry bar to get in under here and pop this up, but this gives you more leverage, so hopefully you'll be able to see what I'm doing I'm taking taking the hook here and I'm looping it under.

So this will work with.

You know this type of seal um.

It's in your heavy duty like ford cargo vans or the uh f250 f350.

So that's so all I'm doing just popping up and bingo that easy.

It's out! Here's what it looks like all right, so I'll! Take this bearing out now I'm gonna clean this bearing out and repack it and grease it.

I'm gonna check the race, make sure there isn't any scuff marks or burning and uh put it back together when we come back I'll, show you how to put the new seal in it's a pretty simple trick.

Well, I decided to throw in some bonus footage, so I'll show you how to pack this bearing real, quick if you're not familiar with it.

So anyhow, on these heavy duty trucks.

This is an eight lug so that that seal, that seal is uh.

Oh, this 07 e250, if you've got a heavy-duty, e150, it'll work and I'm sure some other applications.

So it's 710 625 is this type of seal right here and I'm using this brand.

So they don't pay me to advertise, so I won't say their name anyhow.

It goes there's two different ways: there's like this lip here on the on this edge.

You don't want to bend it when you're putting it in so I'll.

Show you the trick.

It's really easy.

This part here, this smaller diameter ring goes down.

That's going to go right in there, so here's the inner bearing you got to make sure this goes in.

First, of course, you take it out the way you put it in the tapered part.

You can see it's tapered on this side, it's narrower than out here.

So this goes down into the race.

The part that's down.

There is the race, and I checked it.

You want to look for scuffing or pitting, or any type of bluing means overheating.

This one looks fine, so here's how we pack it here comes your bonus footage.

Take uh, I'm using some of this synthetic grease right here this stuff, so I'm going to take a big scoop of it like a golf ball size and I'm going to just lay it in my hand like that and I'm going to take the bearing, which has been cleaned, used, brake, cleaner flushed.

It all out it spins really easy.

I checked that that's also looking real good and then all I got to do is keep I grab it like this got my fingers through here and I'm just going to pack it in now.

You can get those grease packers, I'm sure steve rob's got one of those, because he's got a lot of tools over there check out his channel, but anyhow um I'll just keep forcing the grease through and I'll.

Show you in a second here what you're looking for, so that you know that the wheel, the bearing's been packed properly, so I'm just kind of scraping and I'm pushing and scraping that in all right, it's starting to push through now, basically, there's the inner part of the bearing and then the outer.

Now I don't know if it's picking up on camera, let me see if I can get it for you, there's right in here between the two it's starting to kind of bubble up.

I don't know how else to describe it.

Let me try to clean this up, so you can see it a little better right in the middle here right here.

So that's how you know you've pushed it through, so you want to do that all the way around and I'll finish packing this one and then I'll uh I'll show you how to drive that seal in don't forget to check out my other repair videos.

I have here on youtube.

Leave me a comment down below.

I like comments hit the thumbs up.

I appreciate all my viewers, especially my subscribers, that can't consistently you know, comment on my videos and support the channel so cool.

It's a cool network of guys out there.

Okay, the inside of this rotor, has been cleaned.

I got all that old grease out of there.

I'm just lining it on the inside.

Here you don't have to go crazy.

You don't want to pack this full of grease.

What you want to do is put enough in there where, when it heats up it flows, it melts and it kind of flows around and lubricates the bearing you don't need.

You know five pounds of grease in this thing, so the bearing is all set tapered down, got the grease in there drop that in there, like that, I kind of spin it a little bit just to seat it.

That's good! Now, let's swipe off the top here, just the top edge.

The thing you want to remember when you're packing these bearings sterile.

You want to keep everything clean.

You definitely don't want any dirt or grit or rust getting in there.

Okay, so the bearings down in there.

Here's our seal! This lip is down the smaller lip we set it on top.

Now, if you want, you can slightly tap to try to get it seated in there, but it probably won't work too good, like I just barely got it now.

If you beat on this you'll bend it so here's how we put it in we got it.

Centered just get yourself like a five inch piece of wood to this two by four set that right on top and just start hammering down nice and flush, drive it in and then check your work.

You'll know when it's all the way down there you'll see where it's seated from when you uh originally took it out, and you can hear the pitch.

The tone is different.

See that tone.

I don't know if you guys can pick it up, but that means it's in there.

It's done! That's how simple it is to uh remove the seal pack, the bearing with fresh grease, inspect things put it all back.

Okay, so I hope that video helped you out uh removing the wheel seals fairly easy.

Now, if you don't have the fancy puller wheel, seal puller, you can use a screwdriver or pry bar.

You can wedge it out that way, you can actually take the spindle nut.

Put it back on the spindle.

You know.

Obviously, the rotors off hook your wheel seal right over there between the seal and the back of the bearing yank it off that way.

It'll pop out so there's different ways to skin a cat, but I hope the video gave you a good idea if you need to do this job, so thanks for stopping by the channel, if you haven't subscribed yet please do uh thumbs up is always good leave.

All your comments and questions right there down below and I'll see you on the next one.

Take it easy.


How to Install a Wheel Seal and Grease a Wheel Bearing? ›

Wheel seals can be used with either grease or oil lubrication of the hub. Grease is more forgiving than oil, but oil provides better lubrication. Oil gets right into the bearing and gets splashed up against the seal. It also leaks out when there is a seal or hub-cap problem.

Do you grease wheel bearing seals? ›

Which way should a wheel seal face? ›

A seal must always be installed so that the sealing lip is facing the fluid to be sealed. Why? The lip is made so that pressure applied to it from the “wet” side of the seal will increase the pressure it applies to the shaft.

Which way does a wheel seal face? ›

Most seals are designed so that the “back” (side that faces the fluid) of the shell is open. The front is closed and may have a part number embossed on it.

Can you over grease a wheel bearing? ›

Overgreasing by applying too much grease to a bearing at one time can result in a seal failure and generate heat in the bearing housing. When too much grease is pumped into a bearing cavity, it eventually will become full. If there is no relief port on the housing, the grease will blow through the seals.

Can you reuse wheel bearing seal? ›

You can reuse it if it's in good shape. Then, pull the hub all the way off; the inner bearing and seal should stay in the hub. Check the seal. If it's wet, you're likely losing grease and you should replace the seal.

Where does a wheel seal go? ›

Wheel seals are designed to keep your wheel bearing lubricant within the wheel end, and keep all debris, dirt, and other contaminants out while on the road. They can be installed directly into the hub or onto the spindle with dedicated installation tools, dependent upon the seal.

Do you fill the hub with grease? ›

To keep the bearings from overheating, they need to be lubricated, which is done by filling the inner part of the hubs – the part containing the bearings – with grease. Keeping the bearings lubed and topped off with fresh grease can help ensure you get to and from the ramp safely and without headaches.

Should seals be greased? ›

While the outside diameter of metal-cased seals can be lightly lubricated to ease installation, the outside diameter of rubber covered seals should always be lubricated. Seals with an auxiliary, contacting lip can also be filled with grease between the sealing lip and auxiliary lip to reduce frictional moment.

How much grease should be applied to a bearing? ›

Open angular contact thrust ball bearings for screw drives should be lubricated with a grease quantity that fills ~ 25 to 35% of the free space in the bearing. Freshly greased bearings should be operated at low speeds during the running-in period.

How often do you need to grease hub bearings? ›

With a larger travel trailer, you should grease your trailer wheel bearings every 10,000 miles or once a year, whichever comes first. If you have a smaller travel trailer, however, you'll need to grease your wheel bearings every 2,000 miles. This is because the wheels are smaller and spin faster.

What way do lip seals go? ›

The primary sealing lip should always be facing or pointing toward the media that needs to be sealed. Sometimes seals will have a secondary lip used to keep dirt and contamination away from the bearing system and/or media being sealed.

How does a bearing seal work? ›

This seal is designed to apply continuous pressure on a bearing's inner ring, which creates the contact found in the seal's name. By providing direct contact with the inner ring, contact seals make it extremely difficult for contaminants like dust, dirt, and moisture to reach the inner parts of your bearing.
