Searched this forum checking so see if anybody has done this swap on a 100 series. Couldn't really find anything either about it online, so I just went ahead and did it myself. TL;DR: Have to modify the spine area bushing to get a LS400 wheel to fit.
So I just picked up this '00 LX470 really cheap a few days ago. The original wheel felt like sandpaper with how chipped the finish was. There was a '98 LS400 at a pick-n-pull near me so I went ahead and grabbed the wheel. Alright condition for $20.
Original wheel:
Popped off my own wheel and discovered the 400 wheel wouldn't fit. LS400 wheel on the left, LX470 wheel on the right.
So basically there's a white bushing that's too small for the LS wheel to slide on. You have to cut it down for the wheel to fit. I used a hacksaw to get the majority off and then sanded the rest. Here's a picture of it (already cut) in progress:
Looking back I'd recommend just taking the white plastic thing off. 3 Screws hold it in. I popped it off to clean all the dust out and lube it up a bit. Took a few test fits to get the wheel right. Here's some pictures of everything buttoned up:
Final product installed using the LX's original airbag. No rattles or anything out of the ordinary. The blinker returning to position after a turn still works. I was lazy and didn't swap over the LX's cruise control and wires so the horn/cruise control aren't working. Or I messed up the clockspring. Either way I'll swap over the hardware when I get a chance and try to fix that. Forgot the right side hole covers at the yard so I'll have to go back and get those too when i get the chance.
