Did you have to use the qa1 panhard bar for a reason? Because I am looking at doing this swap and can't find that panhard rod anywhere!!!

I definitely couldn’t use a stock/straight panhard bar with an aftermarket cover. The cover I have was/is the slimmest one on the market. Even with a stock cover I think a bar with a curve around the differential will be necessary. Doesn’t have to be a QA1, but I’d definitely get one with extra clearance.

This thread gave me the info and confidence needed to go find a 9.5" today. I scored a 3.42 G80 out of a yukon denali for $120 and internals looked brand new. I snagged the sway bar and pan hard bar from the denali. For now ill just grab a 3R to 1350 conversion ujoint and spec a 1410 yoked driveshaft later. I know the focus here has been getting a gmt900 9.5" sf into a gmt800 and saw mention about rubbing but i expect this to be straightforward putting this axle into a gmt900 tahoe with the conversion ujoint. I have an extended 26gal fuel tank so it gave me some pause.

Glad this could help someone, I still beat on this rear axle and it’s been great. I have gathered parts for a 4.10 and selectable locker swap just need to get time to install them.

If you have 4wd, does the new rear ratio match your front?

its 2wd which makes this even more straightforward. I sourced the conversion U joint from Drivetrain America, now im just waiting on the install kit i ordered from quickperformance to get here and ill be getting this 14 bolt installed. I was willing to drive a ways out to find a non-XL denali yukon or escalade with the right gearing/g80 so i could have just grabbed the driveshaft for couple pennies more and had the 1350 on both sides to skip ordering the coversion U joint but none were anywhere around and certainly not at the price i got the 14 bolt at.

Got some time and going through the entire rear end to rebuild, what the heck is this inner sleeve? It is plastic and none of the parts stores or rockauto carry it. youtube videos of 14 or 10 bolt rebuilds seem to be hit or miss on this part even being present when other tear down the axle. im putting this back together tomorrow in prep to put in the vehicle but idk if i need to worry about replacing this... ive done all the pinion, carrier and axle bearings/seals minus this sleeve.

I second ABS wheel speed sensor. I think they showed up on the GMT900s(?) Is there a wire on each side of the wheel on the axle?

The GMT800 and prior relied on rear wheel speed via the VSS on either the transmission or transfer case, not on the actual rear wheels.
