Dodge truck guys, help me out here if you can please.
My daughter has this '01 Dodge 1500 magnum, it has a chrysler 9.25 rear end in it and it makes this awful almost grinding noise when decelerating, not when speeding up, not when maintaining speed, only when decelerating. I read up on some of the Dodge forums and thought it was the clutch packs, I replaced those, the ring, pinion, carrier and bearings all look really clean, no metal shavings no discolored oil, no excess play, the clutch plates looked a little worn so I replaced them, got it back together and drove it, still this noise.
I made this video of the noise, this thing has the worst tire noise I've ever heard, it's obnoxious but she likes it, so. You can plainly hear it above the tire noise and wind. Thanks and I appreciate any insight in to what this is.
Hi OM. My Son had a 99 ram 1500, awful noise from rear , everything checked good.. Only thing I didn't check was the wear pattern of the ring and pinion.. 6 months later the pinion gear broke and the rear of driveshaft was left dangling on the ground. Two nights ago, my son stopped to help a disabled 01 ram 1500 on the roadside. Guys driveshaft was dangling. They pulled the diff cover on the roadside. You got it, pinion gear broken! Good luck!!
Wow, that's loud! Sounds to me like the pinion bearings are out of it. Grab the rear yoke and see if there is any movement. Those 9.25 diff kits are actually pretty cheap. Problem is, they don't come with the crown and pinion. If my guess is correct, you'll probably need them too.
Can you hear anything just jacking it up and spinning a wheel?
