No it's horrible.
Runout at the seat, nearest the flats 0.35mm (0.014") Runout at the contact patch worn silver by previous torquing was 0.55mm (0.022") QUOTE What can you guess caused them to bend like that? Mayb not torqued down properly and came loose? I'm doubtful this was installation or usage error. I can really only see this being a manufacturing defect (loose tolerances) because they are all the same. QUOTE Good catch Mark. What made you think to check 'em? When I was unbolting the wheels with an impact driver I noticed more rotational wobble than usual. If you were using a socket wrench you would never notice. Once I realized what was going on, you could easily see the problem when tigthening the lugs. You could see the gap between the bolt and the wheel would vary significantly while screwing it in. Every half turn the gap would go from small to big, then go back again. |
