I got some more progress done today.
Got the spindles off. AutoZone has a nifty tool that screws on the spindle and a slide hammer that beats the spindle off. As tight as they were on there, there was no other way to get it off. Once they were off, a TON of anti-seize went back before the spindle did. The old dust shields were rotton, so they came off for good. I also got a nice new set of MileMarker Supreme lockouts. With the new bearings installed in the freshly turned rotors, the hubs/rotors, and lockouts got installed. I also got the track bar bracket straightened.
I also got the center section cleaned out, diff cover cleaned inside and out, a new gasket installed, and the diff cover installed ready for fluid under the truck. I don't know what the info stamped on the ring gear means, but I hope it means the same thing the tag on the diff says, that there is 3.55 gears installed.
I have to work again tomorrow (24 hours), hopefully the last 2 parts I am waiting for arrive then (track bar bracket & driver side u-bolt plate). Saturday, unless I have a long incident Friday night or Saturday morning, the swap will happen. More to come then.
