Theuprights are like the GT6 unit except that they are drilled for the TR4 taperedaxle (smaller than the GT6 axle). Ibve seen these uprights on some of the more esotericBritish bgarden shedb cars (TVRbs, Elvabs and Loti) so theybre not totallystrange. BUT, I want to put a set of thetrunionless uprights on this ride so that I do not suffer the indignity ofwatching one of the wheels leave the car at some inopportune moment! Herebs thefly in the ointmentb&they only make them for the GT6 stub axle. So, I can find a bearing that will fit the outer end of the GTaxle and TR hub, but not the inner. Seems the closest I can find is about 50 thou larger in O.D. So before I chuck the hub up and bore thebearing hole in the inner TR hub largerb& does anyone have a way to accomplish thissetup without my having to unscrupulously modify the TR hubs?

Don't know how many of those that have failed had the mod done to them but assume that some of the broken uprights on race cars were done and still failed. How did you mod the GT axle to fit the TR hub? You actually don't need to do anything for the outer bearing as Timken lists one to do the job. The inner is the problem. Did you cut the GT axle down to fit the TR bearing? About 60 thou would have to removed from the axle and doing that just sounds like a new place for a stress riser with a stepped axle just as it goes into the upright! Guess this becoming a more difficult mod...was hopin for a simple bearing to fit. Lookin for the simple fixes in life...
