I think i have got ontop of the probs ive been having with it. Teh stripped knuckles it think happened cause i was running the kortz conversion which creates alot of flex in the front, i wont be running that again, ive since put the team prc knuckles on and reverted back to the standard front arm setup and the screws havnt worked their way out yet. The diffs leaking ive fixed...sorta, racers choice air sealant seems to seal them up better than anything else ive tried. I still have no idea why both crown gears stripped at the same time, put new pinons, bearings and gearboxes (for cheap as chips too, gotta love ebay) in as a preacautionary thing cause crown gears arnt cheap. These new rear arms and hubs look really good, i guess only time will tell if they flogg out as quick as the last 2 designs. The car handles great and no doubt (2007 euro's) can keep up with anythign out there, i was just so frustrated at having to replace stuff all the time, was costing me a $fortune$. The car didnt fail in the enduro but my engine did (head worked its way loose, my bad) which was a shame cause the car felt great! Just cant seem to catch a break atm.
