Default Intermittent grinding noise while braking.

I have a 95 Limited with the 5.2L V8, 4 wheel discs, and All time 4WD. Sometimes, when I am coming to a stop, I get this terrible grinding noise. It almost feels as if the brakes are grinding. The brake pads are still in almost new condition so it's not the brakes grinding. The rotors are still like new.

The grinding noise is becoming more frequent, and I'm starting to think that something is going bad. Anyone have any ideas as to the cause of the noise?

Thanks,
Jonathan

Wheel Bearings, 99% sure, time to get a new hub assembly. There is a good wirte up in grand tech. Also search this forum, this is pretty common. Ive replaced each side twice already. Remember you get what you pay for. HTH

Thanks,

I'll go check the wheel bearings. I'll keep you posted.

I checked the front hubs, and there is no movement. Could it be the front differential?

Just an idea...but sometimes an inner pad will wear alot faster than an outer....so when you look at the pads they look new, only the inner is FUBAR. Also, take the pads out and run them on some pavement, then put them back in and see if it still "grinds"

All the pads were replaced last September. They are all pretty much new. I replaced the rear rotors 2 weeks ago, but the noise started prior to that. I changed the differential fluid in the rear diff today. It eliminated sume of the noise. I'm going to change the front diff fluid and see what happens. I put in some 85W140 fluid so the rear drivetrain feels a lot better.

I actually had a pad come off the backing plate so the plate was digging into the rotor. It made a nasty grinding noise. It was an inner pad that I had only had on for a few months.

I took the pads off last week, cleaned the backing, and relubricated them. It didn't really help the noise. The rotors are still smooth, no warping. I'm thinking maybe it's the front differential.
