Binding/growling/grinding

When you go around curves or make turns you hear this, what some call a binding noise. Now starting to feel it under your feet. Seems to do it after the truck has warmed up. Notice it more if I'm pulling a load. No one has been able to locate problem. I had the differential changed out, as we thought there was play in spider gears. Another shop said, there was nothing wrong with my diff, but the front end had worn parts. Got those replaced. The problem is still there and unfortunately is inconsistent. Motor mounts are ok and tranny was look at and minor repairs done.

Driving 50 mph, now feel that something is shifting under the truck, like a back & forth movement. Mechanic can hear metal to metal when shifting from "R to N", but truck is so loud it's hard to tell where it's coming from. Please help! I am at my wits end and don't have money to tear into this thing.

Have the front hub bearings been looked at? That and bad U-Joints up front can do this.

The hubs, outer u-joints, front brakes were done in April with other front end repairs. Heard this noise also, when backing up to parallel park. Guy in shop tryed to tell me, that because I have a locker rear end, that this noise is normal. He has a Dodge. Hmm! Never used to make this noise. Maybe somethings wrong with his. Running out of options, without parting out my truck to find what's making this happen?

I am sending you a Tech bulliten for the rear leaf springs, as they are known to make noises, and new parts have been designed and are now in use, have a look at it and see if this might be the problem. Check your email for it!

My truck is a Cummins. When I hit a bump at say over 3 0mph it starts a grinding noise on the smooth it does not happen unless at high speed. It has been going on for some time but will not self destruct. Transfer case problem or drive shaft? Just came on when I was at high speed on the motorway when off when I slowed to 30 mph. Help

Hi and thanks for using 2CarPros. Com.

Once the noise starts, is there anything that causes it to change or stop? Can you tell approximately where the sound is coming from? Have you checked both the transmission and transfer case fluid levels? Have you checked fluid in the differentials? While the noise is present, does it change if you make a turn? Does it change when you hit the brakes?

Let me know. Since it happens only when hitting a bump, I am a bit confused. A bearing would always make the noise. Since it is related to hitting a bump, it almost sounds like something is loose and rubbing.

I will watch for your reply.

Take care,
Joe

I have a 1997 dodge ram 1500 4 wheel drive and there is a random grinding noise coming from the passenger side front wheel. Brake pads and rotors are new and u joints have recently been replaced. The noise is not constant and usually happens when turning left down hill and maybe braking too. Also bumpy surfaces can make the noise happen some of the time.

Typical of a noisy wheel bearing assembly. A tool that can help locate the source is called the "Chassis Ear". It's a set of six microphones, a switch box, and head phones. You place the microphones on suspect parts, then switch between them and listen during a test drive. Be aware that many mechanics have never seen or heard of this tool. You might find one at auto parts stores that rent or borrow tools.
