Awful Grinding Noise, After Driveshaft Flew Off
« on: May 01, 2014, 07:28:22 pm »
Hello. I recently replaced the U-Joints in my 2001 Dodge Ram 1500 5.9L. As I was driving to work this morning, going about 70, the truck vibrated a little then suddenly the driveshaft comes flying off the truck & onto the road. I abruptly pulled over, turned off the truck, & picked up the driveshaft from the side of the road. Upon inspection, the U-Joints had come apart. The flange was still on the spindle of the tranny, so I pulled that off as well. I am now having it towed.

My bigger issue is, now the truck is making an awful grinding noise when its running. It sounds like it is coming from the transmission, but I could not tell for sure upon a quick inspection (I had to leave it temporarily & get to work). After the driveshaft initially flew off & I pulled over, I did notice the grinding noise then, but I was too concerned with picking up the driveshaft from the road. It also almost felt like the truck would not go into park, but it did, it seems.

Could the transmission have been damaged when the driveshaft flew off? I am thinking about taking it to a shop, but I would like to know what the issue could possible be, so I know a little more of what to expect.

Any ideas what this grinding noise could be? Any input would be helpful & appreciated.

Thank you,

Probably gonna be real hard to tell without a tear down of the trans. Off the top of my head could possibly have ruined a bearing on the input shaft or destroyed the gear on the shaft. If the noise is definitely coming from the trans then a tear down is gonna be needed.

If the truck was in gear and running and you tried to put it in park it could have been the parking pawl grinding because there was nothing to keep everything from turning. Can you get it into park with the engine off and then start it and see if the noise is still there?
