REMOVING INNER REAR WHEEL ON 2003 GMC W4500

U have to use heat. They are lock tited on

is this a rear wheel bearing ! if so most auto-parts stores have a loaner program for tools. you may have to see if you can get a puller for this. just tell them the situation. good-day !

Could be the HVAC control processor is malfunctioning.Wtihout testing that would just be a guess .

why are you trying to pull the ( wheel ) . If you need to replace the 2 broken lugs then all you need to do id hammer them back thru the ( wheel ) and go get 2 new ones that match those broken ones and hammer them back in from the back side of the ( wheel )

That is one of the mode control actuators in the rear HVAC unit, it is trying to move the mode door but is meeting resistance. You can access that area by removing several screws and removing the panel.

Hi, Wheel maybe rusted on. Take a hammer and carefully hit wheel to dislodge it. Do not hit studs.

try this: spin 2 lug nuts on partially(so you dont damage threads on stud) then hit the flat part next to the lug studs... get mean with it... sometimes you just have to destroy them to get them off, rear rotors are fairly inexpensive.

Give it a good hard hammer with a 5 pound hammer. If your planing to use it again, use and plastic hammer or put wood against the Rotor where your going to Hit it.
The rotor is held on by rust to the hub assembly. 
Good luck and wear ear plugs, kinda hurts the ears. LOL

I'm assuming you can't get the rear wheel off. As a previous roadside assistance tech the cause of this is most likely that your 4 wheel drive is on. You have to turn it off to take the wheel off. If it is turned off, then it is sheer force. Keep using a rubber mallet, and lots f leverage as it is rusted on there.
I assume your 4x4 is on though. Good luck.
