Hey guys new to this page and looking for some help! I bought a new to me 2016 ram 1500 sport LB 5.7 hemi at the end of july. About a month after buying it I noticed a strange intermittent grinding noise after hitting a bump at any speed above 10mph. Since that problem came up I’ve also started to get abnormal vibrations in reverse that are more pronounced when backing uphill and also a strange vibration that happens in park when the front of the truck is facing downhill. I also get some strange noise in 4wd but I’m guessing that’s related to whatever the real problem is. When these problems first started I suspected wheel bearings or brakes that were grinding. I was very wrong since I’ve replaced brakes calipers rotors and wheel bearings to no avail. Had the ram dealer I bought it from take a look at it and they said they “couldn’t replicate the problem” which is bs since it did it when I drove off their lot a week later. I have a warranty through ram for drivetrain but my guess is they won’t acknowledge the problem until it breaks completely which is disappointing because I expected more from a ram dealer. Anyway, since then I have ruled out basically all front suspension since it has been to 3 other shops who say they can hear it has a problem but can’t figure out what it is. All front suspension checks out according to every shop I’ve been to including ram. I’m thinking at this point maybe u joints or rear diff. Any other advice would be great because I’m just lost and I can’t keep pouring money into this truck I bought 6 months ago. Thanks for the help everyone and sorry for the long post.
