My steering just spins ? It's solid all the way to the short shaft going into the Rack ? Past that no movement. My question is can you buy internal parts for the Steering Rack or Box ? Kawi seems to only sell the Complete unit ? Has anyone taken that steering Rack / Box apart for repairs ?

05' Crew style , 4X4, 620cc motor. No Vins stamped or any Stickers on Frame ( Front Frame, side Rails or engine area tube or flat panels ?? Where do they hide the Vin #'s ? All i can find is a sticker on the motor / engine ( Mfg. Date 0705 ) ??
