You wouldn't happen to have that same exploded diagram but of the front suspension/hub/brake, would you?

This one is pretty good; https://cardiagn.com/lexus-ls-430-20...repair-manual/

You can save them to your computer, which I recommend doing in case the site ever goes down.

Take the bolts used to hold the hub to the carrier assembly, they go in from behind the carrier assembly through the cover and into the hub, and screw them in the wrong direction from the outside. If you can knock the flanges either clockwise or counter (either will work) to mis align the holes screwing the bolts in from the outside will push on the dust cover and hopefully provide enough force to seperate the parts.

If the carrier assembly holes are threaded take 2 of the bolts, 6 and 12 o'clock, and insert them normally just far enough to be flush with the hole and not allowed to thread into the hub. Then use the 2 remaining bolts, threaded into the same holes from the outside, to push the hub out...

Edit- you'll prob have to remove the brake shoes to accomplish anything.

May or may not work but it's worth a shot.
Just had a chance to try to push and move bolts against bolts in the unit but it is not working. The thread of the bolt got damaged instead. .. this is awfully tight.

Got it. Thanks for sharing diagram. This greatly helps in understanding the surround structure.

What about a slide hammer puller? I doubt you're going to get a wide enough spread with one, so you might have to do a pull on each corner and work your way around till it comes off.

The other option is to use an air hammer/chisel in the same fashion. Just remember to use your safety squints and ear protection. Mine came out with reasonably minimal fuss, I had an air hammer to use which made the job far easier, ans I wasn't worried about trashing the old hubs as they are effectively ruined anyway
Came back to work. Tried this but the thread of the first 2 bolts got damaged. Another option I will try is air hammer/chisel which I do not have. On my way now to home depot. Stay tuned.

That looks good and it might work but do not have that. I get it repaired today. Looks like HF has a similar tool like that. I may go get it. Thanks.

Finally done last night (see pics). Had to take the parking brake shoe off and about 10 min of whacking with hammers from outside. I also used air hammer/chisel but found to be ineffective. Thanks to you all for kind helps. It was a great experience and learned a lot. Two winters ago I replaced a cv axle (front right) myself for honda odyssey but this is my first time working on wheel bearing.

Congratulations! You did it! By the way, what brand of rear hub have you decided to purchase? If it helps, my recommendation is Koyo or Timken.

I’d also recommend Koyo. Closest to OEM.

The TIMKEN I got shows KOYO at the bottom of the part. May be the same thing. See the following link.
