The grease cap part number that you referenced cross references to a drive in cap with a 2.44 inch outside diameter. If you have a standard cap then the Grease Cap, 2.44 inch OD Drive In, item # RG04-060, is the correct part. If you have a grease fitting in the end of the spindle then the Grease Cap, 2.44 inch OD Drive In with Plug, item # RG04-080, would be the correct part. These parts are correct only if the 092101 part you mentioned is correct. The correct inner and outer bearing part numbers are the best way to select parts for the axle and hub you have.

I spoke with our parts supplier and found that the wheel stud part number that you referenced is not a part number that can be cross referenced to Hayes-ALKO axles and hub and drums. The knurl diameter, for driving the studs into the hub, along with the 1/2-20 x 2-1/2 inch dimensions would be needed.

To determine the correct parts for your hub and drum, the most accurate recommendation can be made with the inner and outer bearing part numbers. These part numbers are stamped on the back of the bearings, you will need to remove the hub and clean off the bearings to get the part numbers.
