I have a 2002 Dodge Ram 1500 4x4...I have a grinding noise when driving under floor of passenger side. It sounds like it is when truck is shifting from 2nd into third or could just be at that speed when the noise starts. Any ideas what this could be?

 

also tested it in park and with rpm's going to 2000 and no noise

sounds like muffler system but do not see any issues, seems to vibrate grind at speeds when shifting into 2nd to 3rd. Rev'd engine today and could hear vibration rubbing grinding...puzzled

 

Welcome to DF
I'm going to send your post to the 3nd Gen Ram section. The members there may have some ideals for your problem.

 

Possibly a wheel hub, but if its under the passenger it could be exhaust related as mentioned.
Could it be your jack.
