I like to think Im smarter than the average bear,but is it harder to change the front rotors on a 05 Colorado 4x4 than other rotors?

Remove the caliper & rotor,axle nut & unbolt
the axle hub bearing assy

Watch some video on it

You do both sides at the same time

This the old fashioned rotor. The hub is part of the rotor and there will be an inner and outer bearing. In order to replace the rotor the old bearings will need to be removed from the old rotor, cleaned, inspected, repacked, and then reinstalled in the new rotor along with a new grease seal.

Most newer vehicles have whats called a knock off rotor. This type of rotor simply slips off from the hub assembly once the brake caliper is removed.

what type of vehicle,auto or manual hubs, check front u-joints. since you replaced hubs i imagine you inspected brake parts and rotors. could also be a wheel bearing in front pig. (carrier bearing or pinion shaft bearing)

Do you want to remove the rotor or the hub and all? To remove the rotor, the caliper has to be out of the way and the bracket that holds it on. The nut in the middle holds the axel into the front wheel bearing and it's a press fit. The axel can be removed and the steering Knuckle can be removed and the knuckle be put on a press to push the hub out of the bearing. This destroyes the bearing and you need to plan on new bearings. They do make a puller that can be rented at the parts store that can pull the hub. once the hub is pulled out of the bearing the rotor can be unbolted from the back side of the hub. It's best to do this work on a press as the bearing needs to be installed with out damage and it's harder to get it right with a sleigh hammer.

Front hub bearing, remove tire, remove caliper and caliper holding bracket, you do not have to remove brake caliper from brake hose, just set it aside, if 4X4 remove front axle nut that goes through center of rotor, also remove brake rotor, disconnect elec, A.B.S connector, remove three bolts on back side of hub bearing, remove hub bearing, some times you will need to knock hub bearing out with a hammer.Reverse to install new hub bearing.

2WD pickups don't have hubs. They have rotors with bearings. Once you have the brake assembly supported, remove nut from spindle. Be sure not to strip the threads on the spindle. Remove the front set of bearings and pull the rotor off. Remove the rear set of bearings. Be sure to pack greases into new bearings prior to installation. Insert new rear bearing into rotor and replace onto spindle. Insert new front bearing and washer and re-install nut. Tighten to recommended torque specs, grease fittings and replace brake assembly.

lift front axle and place on jack stands. place front axle on 4x4 and rotate wheels by hand. If front axles are harder to turn than normal then remove drive shaft from transfer case and rotate front axle once more. this will let you know if the problem is in the front axle or in the tranfer case

SOUNDS LIKE THE FRONT OUTER U JOINT(KNUCKLE) MAY NEED REPLACING, AND/OR THE BEARING.

Time to buy yourself a good shop manual. You say it is both a 2006 and a 2008.

My 2004 Colorado 4x4 is at 91K and running better than I would have expected. It seemed to break in at 80K. Still getting 21 mpg. Haven't changed spark plugs yet. No major repairs have been needed except for the power steering pump I'm about to replace because of a squeal.
