Replacement Hub For A 1994 Rockwood 2040 Pop-Up Camper


Looking for a replacement hub for 1994 Rockwood 2040 pop up camper, its stamped AL-KO 7120 on the back side, 4 studs on 4inch bolt circle


Expert Reply:

I called AL-KO and they informed me that there were two different hub assemblies for a 1994 Rockwood 2040 Pop-Up Camper. In order to choose the right hub you will have to do one of two things. You can either measure where the inner and outer bearing ride on the spindle using a digital caliper such as part # PTW80157 or you could remove the old bearings and note the part number stamped inside.

For a inner and outer diameter of 1.063" or part # L44649, you will need the Trailer Idler Hub Assembly part # AKIHUB-440-2-2K. For an inner and outer diameter of 1" or part # L44643, you will need the Trailer Idler Hub Assembly part # AKIHUB-440-2-1K.

I have attached a video that will show you how to properly measure the spindle diameters.
