We do carry a range of replacement trailer brake magnets and you can use the link provided at right.

The best and easiest way to find replacement bearings and seals is to obtain the part numbers from the original parts. My research on your Al-Ko hub 8490 did return results but I could not confirm the bearing set or seals that fit the spindles for this hub.

The linked photo shows the typical appearance and location of these part reference numbers. You can search our site directly with these part numbers. The photo also shows on the spindle diagram the points on the spindle that will need to be measured (with a precision caliper to three decimal points) in the event that you cannot find the part numbers. I also linked at right our main pages for bearings, races and seals where you can use the filters in the left-hand margin to narrow the results based on your measurements. Do note that seals often change shape/size after they are removed from the hub so a part number is best in this case.
