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.

Ask a question to 1A Auto customers who purchased the product
Are the bearings pre-pressed onto the hub?
Chet S September 3, 2015
No you need to pressed the bearing some hub cone as an assembly
David R September 3, 2015 or a machine shop will have to do it.
Adam S September 3, 2015
No, have to be done upon installation .
Howard F September 3, 2015
No they are not you have to press them
Brooks B September 3, 2015
No they come in the same box but they are separate.hope this helps
James L September 3, 2015
No they are not. You must go to a machine shop, or dealership to have them pressed. Alternatively you can purchase a manual press kit and do it by hand.
Nicholas G September 6, 2015
No these are not. They have to be pressed onto the hub and the hub has to be pressed into the housing. I took the entire assembly off the truck and took it to my local garage the pressed them both for $40 and i put it back on the truck. I saved about $150 doing it myself. Its kind of a pain but if your savey with tools it saves you alot of money.
