Unfortunately, Michael I cannot find any information on an AL-KO 7170 trailer hub. I would need for you to see what size bearings your hub uses and send me some images along with dimensions to identify the bolt pattern and any side brakes it may use if it is a drum or rotor style hub. If you are unable to find numbers on the bearings then you could use a Caliper # PTW80157 to measure your spindle.

I wasn't able to cross-reference these numbers but if you're looking for new bearings/races and seals all you need to do is note the capacity or measure. The easiest method would be to crawl under the trailer and look for the axle tag on the…
