Guessworks Feature Product - 1st Motion Spigot / Pilot Bearing
Genuine RHP bearing, which supports the end of the 1st motion shaft with the inner bearing pressed onto the end of the shaft and the bearing race into the transfer case. The bearing and race are a matched pair so both need to be replaced.
This is for ALL non TURBO applications, for the turbo bearing see p/n ADU6033. Please note it is the transfer case which determines if you need the standard or turbo nose bearing and not the gearbox
