Well, that was a interesting day so far. Got the Montana up, wheel off, old brakes removed and removed the rotor. Put new rotor on, put pads in place. Hmm, that'* not right. I pull the rotor off, match it to the old rotor. New rotors are smaller. Dang, wife got the wrong rotors. So I pack them up and drive to autozone to exchange. He says these are what'* listed. I said their to small, I have a Montana SV6. That'* not listed. So he backs up and chooses the 3.5l engine instead of the 3.4l. Guess what, different rotors. Can you check the pads? Yep, those are different as well. Nice. A tiny change in engine size and it uses all different larger parts.
Then on the other side I also changed the sway bar end link.
No more creaking when driving, no more vibration when stopping, much better. Just need to fix the ABS issue. I can't get a clean test. So I'm waiting until I get the correct plug and then make a test harness. I just plug it in and I can connect the oscilloscope.
