Rebuildable HD 1988 Fiero Front Wheel Bearing Hubs $0.00



Finally an 1988 Fiero front wheel bearing hub that is HD and 100% rebuildable!


This is a preproduction sample of my new 1988 Fiero HD rebuldable front wheel bearing.



I originally had a local engineer that had some experience with designing wheel bearing hubs make some preliminary CAD drawings. As this project moved along I contacted Paul Smith and he made some changes to fine tune the design and add some nice features like the thicker flange.

I had the forgings made in China and they are machined, heat treated and assemblied in Taiwan. They come with top quality Japan NSK bearings/races and a double lip rubber seal.



Interior pictures:

 The grease cap is now on the inside of the hub.

 I did not press the steel grease cap on for these pictures


These use common tappered wheel bearings. Both inner (bearing and race) and outer races are replacable and a double lip seal that most auto parts stores will have in stock or can get within a day or so. I will also stock replacement bearings and seals and all the misc parts used in these hubs.


Those that race or want to race an 88 Fiero now have a HD hub that will last long term and is fully rebuildable.


I have had a few requests to offer these in different bolt hole patterns. I can do that. I would have some spindles left not drilled for the studs. You would choose the hole pattern you want. Drill and ream the holes and press in the studs you choose to use. You would supply the studs. I would have them machine in dimples for different hole patterns like 4 1/2" and 5" plus the standard Fiero 100 mm pattern.

If you have a size you would like to have included contact me and I'll look to add it.



OEM GM part number for cross reference:  GM part number 7466939

Interchange numbers:

513040      BR930039       7466939       20-39



I found (maybe) a better steel end cover. I have some samples coming in. I might switch to this cover.



I should have these in stock before the end of 2017 





I do not offer free shipping.

Because I use postal flat rate boxes for heavy orders there is no program that can add the proper amount of shipping to every order. So all shipping is added manually by myself after you place your order. That is explained here: Shipping added later explanation 

When you place an order the shipping amount will show $0.00. Soon after you place an order you will receive an email confirmation that shows the amount of shipping that was added to your order.
