On a side note: For those of you that are getting sick of replacing 950 bearings, but don't want to buy all the parts required to switch to the 1050 bearing hubs (knuckles, uprights, bearings, king-pins, axles & driveshafts), Give the new Fluorine sealed TRF 950 bearings a try. The teflon keeps the dirt out allowing the bearings to last longer. And since they are sealed, there is no nead to clean & relube them. I've been running them same ones for half a season of parking lot racing in the back on my 415 and they are still smooth as butter. I just added them to the front...
eBay seller RDVTG-Hobbies has the best deals going, and he gets parts to the US in about 5 days after ordering. Amazing seller. And at $5.30 a pair (plus $3 postage for two pairs), they cost only a dollar or two more than the crappy metal sheild ones...
