I got off work today around 2:30 and proceeded to work on my co-worker's 2000 Wrangler. He told me the brakes were grinding and that he bought pads and rotors and asked me to put them on for him.
I had done a little research of the torques and was surprised to find that the caliper bolts are to be torqued to only 11 lb/ft.
I started on the driver's side and everything went as planned (about 15 minutes). I moved over to the passenger side and after I removed the wheel, I went to remove the caliper....The top caliper bolt was missing! I removed the caliper and then I noticed that the caliper bolt was actually broken off in the casting of the knuckle. Crapola!! The lower bolt had been stretched enough to notice a difference in the thread pitch with unaided eyes.
I was able to extract the remaining piece of the bolt and procure some new bolts from the parts house. The threads were so jacked from the bolt breaking, that I ended up inserting a Helicoil.
So my buddy comes to pick up the Jeep and I told him of the woes and he proceeds to tell me that the brakes were original and that the only thing that he knew of was that the passenger hub had been replaced after the Jeep dealer had let my buddy's wife leave the dealership after an oil change and tire rotation without properly tightening the lug nuts (The wheel flew off a block away). The driver's side still had the assembly clips on the studs, so that rotor had never been removed, but no clips on the right side. As far as I can tell, the dealer way over torqued the caliper bolts to make up for the under tightening of the lug studs.
Thanks for reading, I just had to vent about something that took me hours (instead of 30-45 minutes) because someone else was either too lazy or too stupid to consult the manual and pay attention to detail.
