Front wheel bearing/hub replacement diy with individual parts

So I had to replace one of my wheel bearings recently and ended up with a Dorman assembled unit. I know there are higher quality options available here, but due to unforeseen circumstances I ended up going this route. I decided to re-use my old hub and buy what i needed to reduild it myself. I have a 20 ton harbor freight press and it worked just fine for this assembly. I included the part numbers for the Toyota o ring and hub bolts as well as the outer seal and Bearing. Also I used a Napa bearing for this build. I know the timken is available and high quality, but the parts I used were all available for purchase and in stock locally. As you can see from the pics, first you have to have a press. You will need to come up with some odds and ends pieces to use for the actual pressing. I used a small weight that was the right size to keep the wheel studs up off the press plate. I used part of the old bearing to push the new bearing down on to the spindle. The key is to be only pushing on the inner races. If you put any force on the outer races, damage can occur. The whole thing went together quite easily. It was actually more of a pain to install the outer seal on the bearing than to press the bearing onto the hub.

 

Is there a diagram how the seal and o rings go with the assembly?

 

In the fourth picture you can see what Toyota calls the "outer seal". It has to be installed on the bearing before pressing together. The same goes for the 4 bolts, put them in before or you will have to try to get it apart to put them in. In the third picture you can see there is almost a black circle going around the base where the horizontal surface meets the vertical in the pic. That's where the o-ring goes. Basically just slide the o-ring down towards the bolt threads and it just sits there. I looked things up on a Toyota parts diagram I found online to see. I would link to one, but my computer skills are lacking in that department. I also greased up the area behind the outer seal and the hub before I pressed it all the way on. I figured the seal wouldn't be rubbing against dry metal . You can see a bit of red wheel bearing grease around the seal in the pics.

 

You could also use the

$30 dorman 930-403 wheel hub for select lexus / toyota models

dorman 930-403 hub and not re-use the factory hub. I figured since I had the original I would give it a shot. The dorman hub is around $30, the outer seal is $10, the bolts are $10 for all four, the o-ring is $5. The only real variable is the bearing, you can go from $30 for a cheap one up to $75 or so for a koyo or Timken. Even if you figured $120 in total parts for each hub you can save some money. 20 ton presses are regularly on sale at HF for under $150. Do your own hubs and a friends, and its a wash, you basically got the press for free if you figure what you save by doing it yourself. I just like to buy tools, so that really wasn't a factor for me. I have had my press for a few years now. If you re-use your Toyota hubs, you save even more. I would bet there is a match for the o-ring at a local bearing shop to save a dollar or two, but I didn't have a good one to try to match up so I had to get it from the dealer. I have seen a video on youtube where the guy didn't even use a press, he went caveman on it and beat it together with a hammer. Please don't do that!

 

Where did you find the OEM bolts for $10 bucks? Local stealership charged like 12 bucks a bolt.

 

My local dealer got them for me. Even had to order them. List price is $2.30 each.

 

That is fucking crazy that the price is so different between dealerships.

Your price is what I was expecting.

 

Damn, the o-ring was just over $5 here. Those bolts are a m12-1.25 x 35mm flange head. Probably could get them from a fastenal or other supply store for around a buck or so. The washer doesn’t need to be crimped on like the factory bolts. Not sure why west coast prices are that much more from a dealer.

 

Because Los Angeles $$$$$$

I will make sure to keep the bolts off the old assemblies.

 

For sure. Unfortunately, I dinged up the threads a bit when i was pulling the hub out of the arm. It was stuck pretty good and I really wasn’t planning on keeping the bad bearing and hub. I am going to be more careful when I do the drivers side this weekend.
