se_shlock 1 Report post Posted June 1, 2016 So I have a 2wd 2006 GMC Sierra vortec max with BV4 package and I lost driver hub today. It has factory 20s. I was hoping to get Timken Ones for it but I can't seem to find them. I'm not 100 percent sure on which ACDelco ones are correct ether. I believe it to be the fw313 instead of the fw310 but tbh idk what the differences in the two are. I can find the Timken replacement for the fw310 but since im not sure on which is the correct oem part number I'm seeing if anyone can help me out. Thanks in advance.
