How do I remove the ignition lock cylinder on a 2006 Pontiac Montana

For the sliding doors you need to clean the contacts, there are 6 or 8 on both sides, just wipe them clean as they are probably covered in oil/grease/grime.

Remove the wheel, remove the hub nut, remove the brake caliper and rotor, put your socket and extension through the hub flange onto the bearing retainer bolts, undo them, release the abs sensor connector if it has it, remove the bearing and hub flange as an assembly, put the new one on and go backwards from here. Torque the hub nut to 180 ft/lbs, your done.

If all the bolts are off, then the gasket is holding the oil pan in place and your going to have to tap it with a mallet, Not a hammer but a mallet so you don not damage the oil pan. Good luck and hope this helps.

SOURCE: Changing the front brake pads on a 2006 Pontiac Montana SV6

no that is only the older rear calipers on gm and others. the fronts do not have that style caliper and sound like the calipers are frozen and may be way your changing the pads. try opening the bleeder screw and then compressing them if they go then you need need brake hoses and if not you need calipers. god luck man
