What are Tapered Bearings and Why Use Them?

Tapered bearings are better than roller ball bearings at handling forces exerted on the bearing during cornering (known as axial load) in trucks and large cars. 

Roller ball bearings have spherical ball bearings between two straight rings (called races). Tapered bearings use tapered rollers shaped like flat-topped cones and two races angled from the outside to the inside of the bearing. The greater the angle, the more axial load the bearing can handle.

Your model came from the factory with tapered bearings. This type of bearing handles cornering forces better for trucks and large cars. Roller ball bearings work well for smaller cars, but replacing a tapered bearing with a roller ball bearing will result in increased wear and faster failure.

Product Fit 2002 Ford Explorer 4X4! Wheel bearing and assembly looks great and felt solid! The online video was spot on and easy to follow! From quotes I got from local mechanics and the big boys, I must have saved $400-500 easily. Two weeks no problems! Extremely happy. Need to do brakes next! Will use 1A auto again!!

Great Product
I bought this for my Mountaineer and was afraid because of the price I was going to have problems with the installation or quality of the part. Installation was easy. I didnt have any problems with fitting and the part was solid. Ive been driving on it for about 2000 miles now with no issues. I would purchase again. Very speedy delivery also, the company had the part shipped the same day.

1A Auto is the way to go for the right parts and very dependable service.
I was greeted on the phone by a knowledgeable staff member who helped me find the wheel bearing for my truck. The price was less than half of most part stores and I received my order in two days. Thank you for getting me back on the road with good quality parts.

Wheel bearing and hub Assembly ford explorer
I have used A1 before to do the upper arm assembly and upper ball joint for my Ford Explorer and the the parts arrived on time and intact. I watched the video on how to replace and completed the job in the estimated time. Sooooo I knew I was going back tot he website when I wanted to replace my front hubs. The video walked me through the installation and the parts matched wonderfully. I would recommend A1 for people who are willing to do the work. Prices are good and the videos are helpful.

A very satisfied consumer LRB
I have nothing but good to say about the professionalism of the staff at 1A-Auto.In the past few months I and my family seemed to be hit by the auto Demon.It is bad enough that your vehicle has issues. But when you have to locate parts for repairs it can be very frustrating and expensive. I was very fortunate to locate 1A-Auto on the computer web site. Not only were the ppl I dealt with professional,they were very pleasant and proficient, the prices were very reasonable.also most of the parts I purchased had as life time warranty. They also provided a tracking number of which you could see when and where your parts would be delivered.

Great site
I cant say enough about A1 they have never let me down , not one time . I have bragged them up to many of my friends and family . Every time someone tells me that they need parts I tell them to go on line and try A1 for the best experience ever. Thank you so much for your devotion to your customers . I will never buy from anyone else again.

Purchase and product working review
I have been ordering from 1 A for years and up to and including this last purchase I have had no issues. The one advantage I Really like about 1a is the fact that I can call and speak to someone if I have questions. The price is right and the delivery time is on or before the stated shipping date. I will Continue to use and I recommend 1 a to friends and family for vehicle parts. Thank You. Darrell E Gregory.
