Can someone tell me what the trick is to removing the front rotors on a 2005 Colorado. I have the tire, caliper assembly, axle nut, and 4 bolts in back of the rotor (bolts that hold the rotor assembly to the steering knuckle) removed but the rotor assembly will not budge. There has got to be something I am missing. Any help would be appreciated. Thanks.

Get out a ball peen hammer and strike it hard between the wheel studs a couple of times. I guarantee it'll come right off.

I'm curious if the hammer trick worked for you fbloss... I tried that also and it was a no go for me. I even have an extractor, and I couldn't get that to work. After that I figured they must be pressed on. I never had experience with a truck that was designed as late as 2004 and I figured itpart of the new design. (Mine's the 2005 version) I ended up taking off the whole wheel assembly on both sides and bringing them down to the autoparts store and getting them pressed off. It took a few tons of pressure to get them off, and to get the new ones pressed back on. Because the truck was relatively new, the clerks at the store said they hadn't seen it before.

All I know was the dealer wanted almost $600 to replace the rotors and pads. It cost me $150 in parts (and the pressing) and 2 hours time.

I may be wrong that they're all pressed on, but I couldn't get them off either... someone let me know if you've run into this as well.

Thanks!

i'd have to agree thy're pressed on also. i had the whole knuckle off and went at it w/ an air hammer and no luck, it was 10:00 pm last night so no presses were avail. so for now it's a pad slap only.

I took everything a part and got nowhere..I re-padded also...I heard GM has an on board
lythe that they can turn rotors on my truck..Anyone have experiance with this?

Is there a lock washer/nut on any of the wheel studs

Are they hubbed rotors? (the hub is inside and part of the rotor)


On-vehicle lathes work really well, but they are tricky to position correctly so you don't end up with a conical rotor.
