04 Yukon rear end

[dadwagon95]

Me again.... So my original Yukon the 2004 GMC SLE 4x4 got a little bit of an issue that popped up with the rear end after I had wrapped it to 4500 RPMs in neutral messing with a Silverado in the same parking lot bouncing off the rev limiter and I dropped her on into drive... Needless to say the 35s did nothing and I mean absolutely nothing but hook and try to book it... Now my passenger side rear tire operates as it should, my driver side however feels like it's about to fall off and does not rotate with the passenger side.... Not sure if I should do the whole rear end or should I take the casing off the rear end and check the gears maybe the axle popped out?
We're just curious if I should go ahead and get a whole new rear end or pop the driver side out and see what's going on with it maybe the pin in the rear end sheared

You did what?!

I mean, sounds like you destroyed something. Pop the differential cover and SEE what you destroyed.

But likely the rear axle will require a major overhaul (read expensive!) A complete rear end from the junkyard swap matching the axle ratio would be probably more economical.

Yeah I know I thought the same thing after I did it I was like why in the actual hell did I just drop that thing to drive

So, YOU are the issue ...

If you get a whole new rear end, or a whole used rear end, you may want to invest in 4.10 or even 4.30 axle gears,
since you mentioned 35s.

Stupid Tax, a common term for money you pay for being stupid.

Pull the rear diff cover and see what you get to pay for.

You may have sheared the driver axle probably be best to go rob one from the junkyard it’s worth pulling the cover to check it out but as stated if you plan to rebuild what you have I’d put some 4.10s or 4.56s in her and a tru track posi
