2500HD front wheel bearing hubs - replacement inner cap for 2wd?
Just bought an '04 2500HD and need to replace one of the front wheel bearing hubs. I noticed that the one that needs replacing is missing a metal cap that covers the splined axle hole on the inside for the 2wd version. I surmise that the missing cap is part of the reason for the bearing's early failure as it looks to have been replaced before.
Problem is I cannot find a replacement cap anywhere. Most parts stores only sell the 4wd bearing without the cap. While I have found a few on eBay, ship times are longer and warranty issues are more difficult to resolve. Any ideas?

Really doubt the failure was due to the cap missing. The splines are inside the hub, not the bearing. The bearing is sealed from the ouside world. Even if the cap was on, waster/dirt/ ect...would get inside the hub splined from the inside. The replacement bearing may not have been a good quality one, or, depending on the miles, may have just worn out. It's possible it was even involved in a curb hit that damaged it.

Re: 2500HD front wheel bearing hubs - replacement inner cap for 2wd?
Time for a follow-up:
Okay, I replaced the hub with one that did not have a cap. Apparently the cap is press-fit into the back side of the hub somehow...it spins with the wheel as it turns. Anyway, I took matters into my own hands to try and protect the back side from unnecessary intrusion of dirt and water. What I did was make a cover by cutting a piece of sheet metal into a disc shape about 3-1/4" in diameter, a little larger than the diameter of the hole in the spindle. Then I snipped and bent in three 1/2" long by 1/4" wide tabs equally around the edge so that the sharp corners of the tabs would hold it in the inside diameter of the spindle. There is a curved notch on the bottom part of the spindle hole to make room for the lower ball joint. So I gave the disc a gentle bend between two of the tabs to match the curve along the bottom. Finally, I coated the back side of the hub with bearing grease to help prevent rust, then installed the cover and ran a bead of ultra black silicone sealant around the edge of the cover. It's a bit ugly but I hope it will keep the worst of the crud and water out of there. I could have painted the covers but I wasn't concerned with looks at this point. I cared more about function. I'll post pics when I can.
