My center support bearing is in need of replacement. I have looked everywhere and can't find my answer. When I look on summits website it only list the 1.378 i.d. Bearing. I have a 2000 2wd 1500 non hd. I know there are 2 different I.d. sizes. Would I be correct in saying that the 2wd non hd 1500 would have the smaller one? The diameter of my driveshaft is pretty small. Do not know if that would have anything to do with it.

Update: I pulled it all apart to find my bearing froze up and was spinning the rubber inside the bracket. I measured the drive shaft to be 2.762 roughly. My truck did indeed have the 1.378 center support bearing. I do not know if the drive shaft on 1500 hd, 2500, 2500hd are different sizes or not. Maybe if someone reads this and does replace the bearing they could measure the shaft and see if they have the same outcome?
