Changing Rear ABS sensor 2006 Lexus GS300
Discussion
Not sure if this is the right place, but any Lexus people on here can help with this. I've tried to pull out the old sensor but it seems to be stuck solid.
Looking at the new sensor its just round and is held in by a 10mmm bold, so should come out, looks like the only way to remove is going to be snap the top off and drill out whats left, is this normal, and will the bits I drill out just drop out the bottom of the hub as I drive.
I've tried to find an exploded diag for the rear hub with no luck. so at the moment its all back together until I tackle it again with a plan.

I'm going to guess that it's the usual thin ally casing, into an iron housing. Electrolytic corrosion over a dozen years does the rest. The only way to get it out will likely be to destroy it.
Smear of copaslip or grease when you put the new one in, and it might come out again in the future.

That's the thing the sensor is plastic but seems stuck fastSmear of copaslip or grease when you put the new one in, and it might come out again in the future.
I wouldn't count on bits 'dropping out'.
Perhaps it's got wedged by a gummed-up o-ring or trapped by corrosion of the housing. Do you have a new one to hand so you can confirm there are no other fasteners and see whether the sensor would/should be free to turn in the housing? That might be an easier way to break it free rather than trying to withdraw it. Ultimately, once you've confirmed it is unfastened, your only option would be to apply as much force as necessary to pull it out, even if that means it comes out in bits with the aid of pry bars and long nose pliers.

This is a problem in lots of cars, not just the Lexus. Take out the bolt then very gently twist the sensor backwards and forwards with pliers or similar till it loosens off.
If you're not careful, it'll snap off leaving a bit jammed in the hole. You can drill this out but you've got to be pretty careful not to go too far and damage the ring on the other end of the hole.

As stated, these things know how to stick in place.
Can you get to the other side of it? The last one I did was a Jeep rear one. I had to take the disc off and then the handbrake shoes until I could manage to get a punch into the back of it, from where I could give it a good smack as there was nothing left to grip on the front of it after I'd tried to remove it from there.
According to the manual, all you need to do is release the bolt and pull the old one out, replacing with the new one. Whoever wrote this has never had to deal with a 10 year old plus one which has been through a few rough winters.

I tried that and sprayed some wd40 on it to try and help but it's not moving, may have to just give it a bit more time, and try again, at least it's not me being a dunce.

the new one is smooth so no o rings or anything else getting stuck.
Sounds similar to panic i had with a Mondeo abs sensor, until someone gave me a simple tip, sounds harsh but worked perfectly.
My old sensor was getting ditched anyway, he said to screw in a long screw, thicker the better, right down into the heart of the sensor as far as it will go, or you feel is far enough, then get a claw hammer, hook the claw part of the hammer under the screw head, then lever the handle of the hammer which 'should' pull the sensor right up out of the hole!!
Worked a treat with mine, i really thought i was stuck when sensor wouldn't budge just by levering it out with a screwdriver or whatever.

I did the same as robbocop33 a few months ago and it worked a treat My old sensor was getting ditched anyway, he said to screw in a long screw, thicker the better, right down into the heart of the sensor as far as it will go, or you feel is far enough, then get a claw hammer, hook the claw part of the hammer under the screw head, then lever the handle of the hammer which 'should' pull the sensor right up out of the hole!!
