2003 Silverado 1500 Ext cab 2 wd 114,000 miles automatic, Just started getting a noise from underneath and at rear of the truck, sounds like a metalic squeak from a stop to low mph, then goes away, rear disc brakes replaced 20,000 miles ago waiting for wife to get home to check rear bearings everything looks ok. Help

my first suspect brakes - did you remove wheel and do a visual?

could it be drive shaft maybe U joint?

how about checking for diff fluid leak- pinion or axel seals?

think easy things first...

I am thinking u-joit...if its like a rotational high pitched squeek...not to bad a job, unless its a two piece shaft..they can be a little tricky for a DIY'er...especially if you have never done one...

It has 2 drive shafts noise coming from carrier bearing where both shafts meet it says that bearing is pressed on any info helpful, also was going to replace just rear u-joint but it looks good

If you do decide to do this yourself, make sure to properly mark the two shafts so they go back together " in phase" or some bad vibrations will show up...
