Here is the vehicle we started off with, the rear brakes locked up on us the other day and almost caused us to wreck the truck. We were told by the Chevy dealer it would not be covered under warranty, and they wanted $900 to fix it but of course the truck had only 10,278 miles on it so we told them to stick it you know where. We had it towed back to the house, and this is where we left off. I put the truck in Park of course, and then I put several wood blocks in front of and behind the front tires just as a pre-caution. Then I took a 3 ton floor jack and positioned it directly under the rear end, I jacked the truck up until I was able to slide the large stand jacks under the ends of the axles. My dad actually made those stand jacks when he was younger, they are actually basement support beams! One the truck was properly braced, I went to work taking off the chrome center caps. All you need is a 22mm socket on a 1/2" drive with a small extension to get these plastic lug nut caps off. The whole cap will come off in several minutes, set these aside until the brake jobs done. Then I took an air impact gun with a steady 90 psi, and I used a deep well 22mm socket to get the regular lug nuts off. I took them off in a star pattern, and I put them in a coffee can for later re-installation. This is what I saw when I took the rim off, for 10,000 miles they look like hell! Although this truck is driven through the Ohio winters, so this is how bad things get up here in Ohio!
