    Won't move in 2wd

    Ya, I'm not building a burnout machine. I do want something of a cross between a capable 4x4 and a prerunner. Something that can tackle some trails and occasionally take flight. I did pickup another pair of front and rear diff assemblies. Stock configuration GT4/G80. Might tear my originals...

    Where did you get it? Is there a way to beef up my front diff without doing a 2500 swap?

    Not to worried about the rear axle. They make coil spring brackets that can be welded on. More concerned about the front. As in, mounting point locations being the same or not. Would love to see a write up on that! Pics? What parts do you have to beef up your G80?

    So instead of AXP on the glove box sticker it would have AXN? Is this still a positrac? Is it better? Thank you. I see your a mile high! I lived in Grand county, for 23 years. Sure do miss those mountains!

    Yes, these are from my tahoe. I know the GT4 is 3.73 and the G80 is Positrac, what's the G63 in between them? I can't find it on any RPO codes list. I thought it might be the front diff code, but again can't find that anywhere. And thank you for that. That is what I found also. Does anyone...

    That's actually the only info I can dig up is for Silverados. I'm sure I'll end up with 3.73's which is fine for now. I have a set of Dana 60's that I have considered swapping in. But I actually like the thought of a prerunner build for this Tahoe. Want to get this on the road for now so I can...

    Well, here she is, in all her glory! I willgo to the boneyard shortly and grab another door. But first I must address this. Kinda hard to tell, but that is my rear pinion gear. Mirror smooth. Where did the teeth go? There's some of them. I can't believe this thing even moved on its own. The...

    Won't move in 2wd

    So story is, I've known this truck for the past 15 years or so. Colorado truck. Very little rust. Young guy bought it and put a 4 inch lift on it. Aftermarket wheels and bigger tires. Everything else remains stock. Father in law bought it 10 years ago, never did any routine maintenance on it...

    Won't move in 2wd

    That was my thought as well. Probably pull apart just to see what it looks like in there. Yes. I drove it home in 4wd. Both 4HI & 4LO work. I was very worried that I wouldn't make it because the front diff is all but shot also. So with the truck on the ground, 2WD, in drive or reverse, the...

    Won't move in 2wd

    Hello, All. New here. I have scoured this forum as well as many others and can't seem to find the answers I need. So I thought I would ask yous guys. I have a 2004 Tahoe Z71 4WD not AWD. Just aquired. The issue is, it will not drive in 2wd. It will drive in 4wd. The rear drive shaft IS...
