Review on Improved Ford AC3Z-3B396-A Front Axle Hub Link Assembly for Unbeatable Performance by Centerfold Montague

Fits like a glove. I'm not sure how this person can sell them so cheap, but they look and feel like standard Ford locking hubs have been pre-lubed. Be careful when inserting, don't force them, just twist them until they go in with minimal effort. The old ones I had were still in decent condition, but a couple of the plastic pieces that were inside closer to the outside had broken off and were swimming in grease in the hub. So I swapped them out just in case since I also swapped out the front wheel bearings. While the hubs worked great, replacing the front wheel bearing after 13 years of use, including towing the fifth wheel, made a huge difference. There seems to be a lot less noise from the front wheels. It wasn't the sound of the tires that sounded like ru-ru-ru that didn't seem to match the speed of the tires, it was coming from the tires. All the noise was coming from the wheel bearing. I bet I also got a 1mpg improvement and regained at least 5% of the power loss due to all that old wheel bearing friction. Buy a TRQ brand bearing. Great price and solid review.
