Well, the IAT (Intake Air Temperature) sensor is located on the air intake duct between the filter and the throttle body (Assuming you have the 6L motor). The wires are easily visible at the plug that connects the sensor to the wiring harness. That's the easiest place to access them.

* All brake rotors have a discard dimension cast into them. Replace any rotor that does not meet this Specification. After refinishing the rotor, replace any rotor that does not meet the minimum or discard thickness specifications.

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 ; )

if you put your vehicle information in at advanceautoparts.comyou can search sway bar and find parts that you need - there was someinfo missing on which sierra model you have as far as engine size andvin # match but I came to: http://shop.advanceautoparts.com/webapp/wcs/stores/servlet/partlist_Sway-Bar-Link-Kit_78_R|GRPCHASAMS__sway%20bar___

your description sounds like the gears inside the the same differential you just replaced.
