Hi I have a 2003 hondatrx400ex,,,,so here's the deal,I need bearings and housing so I went on eBay and ordered a black path with 1 doubl row bearing on each side,,,each side only has 1 bearing but there wide double row ones,,,,,sorry just make my self clear so u can picture what I'm talking about,,,,o.k. So I go to install in got it in and after I put the brake caliper holder on it was a hell of a time to get that clamp on ,I had to get a punch a hammer it in the grooves,,,,and then I put the brake disk rotor hub on and the jam nut assembly when I got it tight then I discover there's a gap between the brake hub and the carrier so it throw my caliper placement off,,tried to bring out the caliper with washers but just couldn't get it righ,,,,,,so I grinder down the brake hub till was sug against the carrier and caliper went back on just fine,,,,,,can someone tell me the issue I was having and when I get the correct carrier and bearing do I need a new brak disk hub since I grinded it down,,,,,,

I have had issues with a few of the cheaper brand double row bearing carriers. I think there bearing seat depth is wrong and the bearings dont go in deep enough as a result. Lonestar and rpm are only aftermarket ones i would ever suggest. Rpm is taper bearings so it handles a side load alot better.(For racing) and the lonestar is just 2 big double wide bearings. I honestly run stock single row bearings. And as long as you keep the nut tightened properly and bearings pre-loaded right you dont have to worry. The reason the 400ex is plagued with the carrier bearing failure is that lock not loosens and then the bearings lose pre-load and before long get destroyed.
Yes you will have to replace the rotor hub also. That surface sits right against the bearing itself. So if you grinded it down when you get a lonestar or the like it will be in to deep and probably throw things off alignment. And no problem! Im always glad to help!
There is no way for me to be sure what you did will last. I dont know your machine work skill level. But i will tell you if you didnt get the rotor hub grinded perfectly flat i would bet it takes out the bearings in short order and mostlikely the brake pads will wear uneven aswell. All of that stuff has to be in pretty close tolerances and alignment to work long term.
No worries bro! Glad to help anytime i can!
