Expensive but worth every penny
The National bearings are much more expensive than the competition. I did front rotors on my light truck and had to buy inner/outer on both sides. However, the product is excellent quality and a trusted name. Also consider, how many times are you going to replace front bearings on ANY car? Once? You might at well do it right while you have the rotors off! Don't be affraid of this repair...JUST DO IT!

Bearings boxed wrong and no one tried to help figure it out.
Purchased 2 A2 bearings. They barely came out of the box because they were such a tight fit, Once these were put next to the ones on the truck, we realized they were too big. We took them back to the store when we exchanges the seal and they parts guy said that was the only option and told us we would have to bring the original bearing in so they could match it. My son thought that maybe he had compared the sizes wrong so we took them back and tried again. I could see that he was right , the new bushing was much bigger than the old one. I started to research the measurements on the bearing your website advertised and they did not match the size of the bearing we received. We decided to go to AutoZone to see what their bearings looked like and they were exactly what we needed. After three different trips to your stores plus a stop at two stores to find the replacement seal, we have decided that although you offer deals and coupons and most of your employees are knowledgeable and helpful, we will be buying our parts from your competitors. We live in an outlaying area so we need the right parts the first time.

Bottom Line Yes, I would recommend to a friend
Rides much better and quieter
Verified Buyer -
Went in easy. Don't forget to have or get grease and couple of pairs of latex gloves for the grease pack. Completed inner and outer on one wheel in about 1 hour ( not counting socket search time...to drive out inner bearing)
Bottom Line Yes, I would recommend to a friend

National Front Wheel Bearing, A-2
Verified Buyer -
Each came sealed in plastic in a box. Each comes with the outer race (red part of the picture). I used these while replacing all the front pads, rotor-hubs, bearings, and seals on a 1997 Ford Explorer (RWD). These A-2 bearings matched up with the dimensions on the old ones. Packing these bearings by hand was more difficult than the larger A-5 bearings for this same job. The new rotor-hubs had races already installed, so I didn't need the ones that came with these bearings. The only con so far is that I dropped one. No scratches or dirt in it, so we'll see.
Bottom Line Yes, I would recommend to a friend
Exact fit

Really like the online order process. Everything ready when I got to the store.
