I know there's hundreds of other threads on CV boots tearing and replacing them on AWD IS, but after searching for an hour on the forums and stores I can't find where to purchase the actual BOOT that's needed to replace it. From what I've read CV boots aren't universal but for the life of my I can't find one for a 2011 IS250 AWD.

Mine tore pretty bad and flung grease everywhere which I expected at some point since I'm riding pretty low for context. Only happened on my driver side so far though. I'm just looking to get it fixed soon but I don't want to cheap out on anything for a temporary fix.

There aren't any symptoms of the boot leaking however, I just noticed during a maintaince check, so I don't think I need to jump to an entire axle replacement like many people seem to do for some odd reason. I just need to find where I can purchase the boot. Not even Lexus.com could verify any fitment.

Just make sure its the correct part for the AWD.
