2008 silverado rear end whinning

[jdunn01]

Ok new here but trying to find out what year rear ends are compatible with my 2008 Silverado 1500 Crew Cab 4x4 5.3 Litre. The rear end codes are G80 and has JF3 and JL4 with drum brakes.

I am pretty mechanically inclined and have even tore the motor down to replace the lifters after one collapsed but the i don't have the tools (gauges, bearing press, etc) to tackle the rear end.

So that leaves it to purchasing a rebuilt or used one and replacing myself. I can find very little about what years i could potentially replace this rear end with but do know i don't want to try to go from drum to disc as that seem like utter magic to make work.

Any help is appreciated.

Thanks in advance Jim
