Question about GMC Sierra
Found problem. Removed differential cover and found 1 spider gear and half of limited slip mechanism on bottom of differential housing.
check the sway bar kinks for play both rear wheels will have to even ramps work good if you have them if the is any play in the links it wil rattle also check for play in the bushings that the bar goes threw tis will also give you the noise you complain of

remove cover.take off back wheels and calipers (or drums).turn differential to where you see small bolt/pin (5/16) horizontally (same direction as axles)on right side of differential.remove bolt/pin.A large pin (about 5"long 3/4"diameter) should slide out differential with ease ( you may have to tap one side of the large pin).turn differential to completely remove large pin.turn differential so you can see in the view window.push each axles in (they'll go in about 1 1/2"each) You may hear one of the axle C-clips fall.If not use a small telescoping magnet to remove the C-clips from the axles through the differential window.pull each axle out about 10"so they are out of the diff.Now remove the cap bolts(4-5/8"bolts) and remove the caps(mark the caps so they go in excactly the way they came out.be careful the diff might fall out.If not you may have to use a long bar or 2x4 to wedge and pry the differential out. Have a basket/crate w/rags in it to catch the diff.TIP:If you are removing the ring gear from the diff, the bolts are left handed bolts meaning you have to turn them clockwise to loosen and counter clockwise to tighten ; )

Testimonial: "thank you helped ALOT perfect instructions "
You will have to remove the rear end plate off of the back of the rear end. Then turn the carrier untill you see a big silver pin that goes through the spider gears. Those will be 4 small gears in the rear end carrier. If you look at the right side of the carrier were the pin goes through it you will see a small bolt head, That bolt goes through the carrier and holds the pin in place. Remove that bolt then reach up in the rear end housing and push the pin towards you untill it comes out. ( DO NOT TURN ANYTHING AFTER YOU REMOVE THE PIN) are the spider gears will fall out.
Now get someone to push the axel in while you are looking at the 4 small gears in the housing, when they push the axel in a C-clip will fall off the end of the axel and into the rear end, You will see it fall out. Then just pull the axel out.
When you put the axel back in, push it all the way in then slide the c-clip over the end of the axel and then pull out on axel and that will hold the clip in place untill you put the big long pin back in the carrier. I hope you understand, just watch what you are doing. GOOD LUCK.
