Hi, I recently am having a problem with my durango, it is making a humming noise which seems to be coming from the rear. It starts to make the noise at around 25/30 mph and up only when I'm on the gas pedal, and when I come to a stop from 20mph it hums and seems to grind a small bit too, but only when I come to a stop. I have checked the wheel bearings and I don't think it is a bearing problem because the wheel doesn't move when I try to shake it, and it only occurs when in gear and getting gas. I had recently gotten a flat tire in the rear about 2 weeks ago and had it repaired, but I don't think that is problem because it makes the noise on gravel and dirt roads. Any help would be greatly appreciated! Thanks!

This is a straight axle like a pickup, so the test for the front end isn't the same as the back end. Have you looked to see if it it leaking gear oil? What level is the rear end at? Pull the rear wheels and brake drums off so you can grab the axleshaft without the brakes hiding any play. See if you can move the shaft up and down. If so, bearings are shot. They take a special puller which uses a slide hammer to remove, and you have to take the diff cover off, pull the cross pin and c-clips to pull the shafts.

I took it to my mechanic and he is going to put it on on the lift this Tuesday. He says it could be a
worn pinion bearing. I'm going to have him check the gear fluid as well so I will update this Tuesday.
Thanks for the response!
