Pc of cake. Its a left hand bolt goes right thru the center, remove the bolt with a socket and rachet not too tough to do , then just let the belt lay to the side and remove the bolt and the pulley falls off in your hand. On both sides around the bearing is a seal, take a pocket knife point and pop out the seal on both sides. Clean and spray it real well with WD40 and blow it dry. Then use some good Hi temp wheel bearing grese and pack it in on both sides then wipe the exces and press the seal back in with your thumbs. Re install the wheel remember its a left thread nd put the belt back on and listen to the quiet !!
