Hi everyone. I have a new to me 2006 yukon XL Denali. I am very certain I need to replace the front left wheel bearing/ assembly. From what I've been reading I have to replace the whole assembly, not just the bearing. Correct? Also should I go with the factory OEM Timken setup? Has anyone done anything different that enabled something that makes it better than stock? Maybe a 3/4 ton assembly or a newer generation assembly?
