Seem to work fine so far
I bought these for my '02 F150 that was having a growling sound from the front end when moving, so I figured they were due for replacement. These bearings are on par with Timkin IMO (National is owned by Federal Mogel, and they also own Tinkin). These have a metal cage compared to the plastic of OEM (and Timkin). Plastic seems to work fine, but metal just gives me better piece of mind. Install was simple, just remove old hub assembly, remove race, install new included race (you can use the old one if you want but it is best to replace both), pack the bearing (I used Valvoline Synthetic bearing grease), do the same to the inner bearing and install. I replaced both sides, even though the other side was fine.

First time putting in bearings. Was pleased in the end. They seem to be what my truck needed. Make sure to buy two because "set" means the race is encluded. just a FYI
