Installation of the Dexter Trailer Hub Assembly

Today we're going to take a look at and show you how to install the Dexter Axle EZ Lube Trailer Hub Assembly. This has the 6 on 5 1/2 inch bolt pattern and it works great for 5, 200 pound and 6, 000 pound axles. Part number is 8-201-9CU3-EZ. Now, on the rear axle we've left everything just as the trailer rolled in, so now we'll go ahead and show you how to install it. First things first, we're going to remove the knock off cap that goes on the end. This is essentially a grease cap. There's a rubber cap here that allows us to get into our greaser we just want to get this out of the way using a rubber mallet.

We're not going to be reusing it so if we dent it or ding it up a bit, it's not really a problem. The new hub that we're going to be putting on comes with a new cap. Now we can take some shop towels and start wiping out some of the grease that's inside of there. Believe it or not, behind all that gunk there's going to be a cotter pin on the nut that we're going to remove. We'll just get enough out of there so we can see what's going on. Here you'll see our cotter pin, it's hiding in there.

Here's the bottom of it. Here's the top. Usually a pair of needle nose will do a good job of getting this straightened out. You'll want to line those up and then we'll pull down here on the bottom to try to get it to come through. Here you'll see the cotter pin that we removed. Most of the time, you're going to bend them, twist them or damage them.

We could pop that back out, just kind of tap it with a hammer, flatten it back out. This would be about on the marginal side of salvageable, but you can certainly order a couple here at etrailer that way if it does happen you'll have them there and be able to take care of it. Now here we have the larger hub nut. What we want to do is loosen that up. Once we have that off, we'll hold onto it because we will be reusing it, as well as the washer that sits right in behind there. Now with those removed, right behind that washer is going to be outside barring.
