Sierra rear end swap

[txbob1000]

I have a 2006 GMC Sierra 1500 crew cab Z-71. The truck has 80,000 miles.(i've owned it since new). The pinion seal failed and I lost most of my rear end lube before I discovered it. I drained and cleaned the diff and changed the pinion and axle seals. I filled it with Mobil 1 synthetic 90 weight. It was too little too late. The rear end is making a growl. My rear end has drum brakes. Can I swap in a rear end that came with disk brakes(using my drum brakes)? What years will swap easily. I believe my ratio is 3.42. Thanks, Bob

If you swap make sure you get the same gears. 99-07 classic gmt-800s will all should swap easy.

Will tahoe or yukon or suburban rear ends work?

No. They have coil spring mounts.

Also the hydraulic system of the brakes is controlled by a proportioning systems that is different for drums than it is for disc.
