I have just baught a 2005 limited all wheel drive, and we noticed a vibration under braking, and assumed that it was warped rotors. We also had a grinding noise in the rear , but thaught that was due to the fact that it needed new tires, since that helped our navigator. Well the wheel came off on the freeway, and my wife got it off of the road safetly, while watching the tire cruise up the road about 400 yards. Thankfully it was the right rear, but she ground down the knuckle pretty bad. Chrysler wanted $426.00 for a new one, and they were on "major" back order. It looked complicated, but I was able to get it apart, and found one from a rollover at a local junk yard. They pulled the part and it was $226.00. I got it back on the road, and the brake viberation went away. I found out that the grinding noise was from the bearing going out, so i think that might have affected the abs sensor, mabey from the heat?? It saved us around 600.00 dollars for a brake job. I hope this helps someone. We were pretty lucky this time..

 

hi, thanks for that info. i have a 2004 pac awd, last week started making a grinding noise in the rear, cheked the oil in the differential and was ok, and i have a feeling it's the bearing. my question is where that bearing is located and if you have any part number it will be appreciated.
