What did you do to your NNBS GMT900 Tahoe/Yukon Today?

My back is worth more to me... at 64 I am trying to be kind to myself. Saving myself up for changing the air compressor for auto-ride...

Fear not. Having recently replaced my compressor, I can tell you that it's surprisingly easy. The hardest part is separating the wire harness plug because there's no slack and it's on top.

There's three nuts (14mm I think)- two towards the back and one towards the front. Loosen the rear until they're about flush with or above the studs then give 'em a couple whacks with a hammer. They're splined studs that grip the frame when you tighten the nuts so knocking them back out just a hair really loosens up the compressor. The front nut is loosened via access through a hole on the insideof the frame. Once loose, you slide the compressor up and towards the back so the stud heads can come out of the keyed slots. I got the rear studs out and left the front one in the slot in the frame so the front of the compressor could hang as I rotated the back part downward to better access and separate the wire harness. After that and the airlines are disconnected, just slide the compressor up and to the back to get that front stud out of the slot/hole and it's free to go. Hang the new one by the front hole and do everything in reverse order. I'd estimate it to be about a 20 minute job working on the ground.

Not bad for not touching a welder for 6 years. Also borrowing a new to me welder i wasn't familiar with.

Not bad at all.

guess it's time to do the gruven mirror gears my passenger mirror keeps getting stuck in, I can get it to go back out but I have too do the stretch out the window push on the mirror and hit the button at the same time. those that have done it, was it hard?

No it's not terribly hard... they provide good/lengthy instructions.

I bought the gears that were already attached to the shafts, so I wouldn't have to wait 24hrs for the epoxy to cure, as well as their HD motors.

Got me a weekend project. Part of the 100K mile service: 5 gal ATF, 1 gal of gear oil, gasket & filter.

I’ve never done this myself. Aren’t the tranny pans on these GM trucks notoriously difficult to get off because of the exhaust pipe or something?

Mountain out of a molehill, imo.

I need to do that. I assume the transmission pan doesn't have a drain plug. So I'll have to add one.

Can I replace it without jacking up the SUV? Just laying on the ground???
