For do-it-yourselfers on removing the front wheel bearing hub on a LS460; I know removing the hub can be a problem due to the Galvanic corrosion between the two different metals causing them to bond. This making it a grueling task to separate the bearing hub from the spindle knuckle. My question is, has anyone tried to back the bolts that secure the hub to the spindle knuckle about 1/8" (or whatever) and then drive around the block making some nice, tight left hand turns (for right side removal) including traversing some speed bump,to loosen the hub for easier removal? I'm not talking about a three day excursion, I am just suggesting enough travel and stress on the components to jar it loose. Has anyone ever tried this?

I did try to loosen the bolts 1\4" or so and drive around. Absolutely nothing happened while driving. I made some hard fast turns too.

I ended up using an air impact chisel. The trick is to not worry too much about damaging the knuckle it will get beat up a bit on the edges. I angled the air chisel between the hub and the knuckle. I tried to stay mostly on the hub but on occasion I did contact the knuckle. To speed things up on my second one I started by chiseling directly between them to force them apart. Once they start to separate jam a screw driver in the gap. Then hit it the hub with the air chisel from the other side. You have to work it out evenly. Once it is out grind off any imperfections in the knuckle so the new hub fits smoothly. The knuckle has plenty of meat to it a few gouges and scratches won't hurt it.

Both of mine were very stuck. A good quality air chisel with a good compressor are key. You need a lot of air. There is no way mine would have come out without it. I tried these with no luck chains, sledge hammers, torches, driving around with bolts loose, ect. The impact chisel and flat head screw drivers had mine out in 10 minutes.
