I JUST did mine so from the knuckle out .LARGE RUBBER SEAL OUT sbk1 kit..put in the inner bearing an a small seal in the SBK1..If you get the kit from NAPA then it has a fiber washer that goes against the spindle..Next is the large 4250 seal ...I believe the bearing no.s are B35 &B37 MAY BE B45DONT remember those no.s I can edit when I get home..I'M ON son's computor.. The older orginal kits have a metal cup that holds the large spring...the large spring one end is larger than the other in my kit ..one end of the spring will fit into the wheel lock set up ..the part that warn or so sells mine had a ring that one end of the large spring goes into ...Then the outside locks go in ...very large snap ring 3or 4 inch ring ...and then the snap ring on the end of the stub shaft ...you'll need a large screwdriver to go behind the u-joint to push the stub thru the lock so u can put on the ring...then put the chrome cap on the outside..6 screws 9/64 allen hex..
