I recently replaced the shocks on my T1N and noticed a long irregular mark on my left front wheel outside of the lug holes spanning three lug holes. I felt it with a small pick and couldn't feel anything, I then sanded part of it down and was able to get it to disappear, but I could have just smeared the edges over so isn't visible. Without doing some sort of dye penetrant test I can't know for sure, but the dye penetrant kit is almost as much as a new wheel. If it is plausible that it could be a crack, I may just go ahead and order a new wheel and skip inspecting it. So, has anyone ever had a steel wheel on a Sprinter crack in normal use?
