Broken wheel stud
Yesterday, I changed the oil and did the maintenance for my wife's GX470 15,000 check up. After rotating the tires, I snapped the wheel stud on the passenger rear wheel when tightening the lug nuts...by hand! I didn't tighten it too hard, but it snapped.
It cost me $6 for a replacement stud from the dealer, and I had a pain removing the rotor. I had no idea that the GX470 had drum brakes as well as disk brakes on the rear.
Does anyone know an easy way of removing the rotor from the rear? What a pain in the b*tt! I couldn't adjust the self-adujting screw because there was no slot to stick a spoon or screwdriver through.

Kurt,
I just pulled this quote from www.lexus.com - GX470 spec sheet:
Four-wheel ventilated power-assisted disc brakes
The sheet makes no mention of the DRUM brakes Just wondering how you came to the conclusion that it has both?
(about 3/4 down the page under SAFETY section...)

Thanks in advance!

Can't have both
You either have drum or rotor but not both on each corner, 
I think he talking about the deep rotor hat, it look like a drum.
How can you snap off the wheel stud , they can take up to 120ft lb. easy. That hard to do with the stock wrench.

I managed to pull it off the first time to replace the stud by brute force. After I replaced the stud, I wanted to readjust the self-adjuster on the drum brake and couldn't get the rotor off. I made the mistake of putting the key in the ignition and turning it on to move the gear shift from park into neutral, and I could hear the brakes moving. I snapped to key to lock/off as soon as I heard it but it was too late. The caliper for the disk brake completely closed and I had to use a c-clamp to recompress the piston. After that I couldn't remove the rotor again.

I Googled a search on the 4Runner wheel stud snapping and found someone else who did the same thing on his 4Runner (same part as the GX470 stud). He was using a torque wrench to tighten his lug nuts and came nowhere near what he wanted to tighten the nut to (70lbs?) and snapped his right off. So, when I bought the replacement stud, I bought an additional just in case this happens again.

Allow me to answer as to why some of us do things ourselves:

I was just curious why would anyone do this type of thing when, in the long run, there could be some warranty issue with the lack of service records. I am personally comfortable with the knowledge I have worked on cars in my youth, but I would really hate to hear that something was installed incorrectly and violate the warranty replacement. Again, I was just curious as to the reason ....
Also, I am a cheap bastard and decline to pay someone $100 for a simple task I can do in 15 minutes for $20 of parts. Sometimes its faster to do it than drag the car to the dealer for a 3 hr production.
This said, not everything is worth doing oneself. While I'll rotate tires & do oil, etc, I am not about to change the diff oil as I lack a lift!

I'm guessing that it wouldn't be since I snapped it off. :-(
You can try calling your Lexus dealer and see if they would replace it. My dealer is el cheapo.
