Generally this occurs during heavy articulation when front sway bar links are disconnected and longer shocks are installed. If this is found to occur, the proper procedure would be to replace the oversize factory shaft with an aftermarket smaller diameter shaft to increase clearance between the transmission and front driveshaft. Rough Country does offer this driveshaft if needed. 2007-2010:2WD:Jeep:Wrangler JK Unlimited;2007-2018:4WD:Jeep:Wrangler JK Unlimited
