My 1999 Dodge RAM 1500 4WD pickup has been making progressively worse noise. Noise comes from the rear. It sounds like a bad bearing noise, I recalled my experience with a 5 hp single phase Baldor motor that I fixed by replacing bearings, it sounded very similar. A screechy, crunchy sound. Noises appear at speeds between 20-40 MPH.
Any idea what it may be about and whether this is a DIY type repair. Thanks.
