First off: Sorry reviving an old thread but, I could not find any updated thread, as it seems no one around here really cares. If I can find this thread, then some with the same question might benefit from the information.
It's been a couple of months and a lot of procrastinating, and the 2 month heat wave finally subsided in SoCal. I got around to start replacing my warped rotors on my '93 4x4.
My first hurdle was removing the Lock Hub. The six 12mm nuts were a breeze, but the cone lock washers were a PITA. I ended using a 3 lb hammer from the local Harbor Freight. After removing the Lock Hub, I noticed there was a paper gasket, that no one told me about. It would have been OK had the gasket been intact but it tore and was stuck to the lock hub and hub assembly. I continued my disassembly to get the rotor replaced. The rest was a breeze. I removed the axle nuts and lock washers. Pulled off the rotor/hub assembly, after gently removing the brake caliper. (BTW, There is a YouTube video on how to remove the brake caliper assembly.) Removed the six 14mm bolts that hold the rotor to the hub assembly. Installed the new rotors from RotorsWorks (cross drilled and slotted). Re-assembled the whole thing, less the gasket, which I found is not available from the any parts store. I had to special order it from the Toyota Dealer. Part No. 4342260010
Before replacing the lock hub, I scraped off the remaining gasket off with a razor blade and box cutter. Then reassembled the lock hub assembly, less the gasket. I wanted to get the wheel back on while I wait for the gasket to arrive at the dealer in a couple of days. Since I got over the big hurdle of getting the lock hub assembly off, I figure it would be a breeze the next time. Also, just in case I needed to use my Truck in the mean time. I only finished the one side, since it's no use doing the other side without a gasket.
In the following days, I'll post photos of the other side dis-assembly and replacement.
On a side note: Just in case someone wants to add Manual Locking Hubs, this is a good time to do it. I wanted to change mine but, I have not found a set I like and I really needed to replace my rotors, badly. There are 26 Splines on my axle, just in case someone needs verification.
