Yukon Down, AWD delete, headers, converter etc...

Absolutely not. No issues. Like we talked about, the axle doesn't hold the hub together, the bearings are press fit and non serviceable. IF, in the event of a complete failure, your axle would help being there, though it would probably still break your brake caliper bracket and send you off the road. Most people report bearing noise before a complete breakage/failure. I would highly advise if you hear any noise investigate it before it comes to that. But you should do that anyway.

What brand spindles did you use? Saw a few pages back you picked some up, and how bad did it ride with the stock keys adjusted? I want to do a 2/3 but debating lowering keys or spindles

I bought the spindles off ebay. Can't remember the store name but it seemed to sell a bunch of them and had 99+% feedback so i took the chance. Zero complaints. Ride has always been pretty decent once I got rid of the stock shocks which I think werent working correctly.

Recently discovered some pitting on the chrome wheels. I think it was a combination of lack of maintenance/upkeep and cheap wheels. The chinese tires were also dry rotting I guess just due to age cause they still have a ton of tread. Found these local for a steal so I scooped them up. Same size as before 305/40/22.

Do spindles

Those are

Those look great.

Long story short, this 60e has been fighting me again. It's always had a harsh 1/2 shift, so like a clever hptooner I took some pressure out. It worked really well for about 100 miles. Then 2nd starting slipping. I added the pressure back, it stopped slipping after another 100 miles, harsh shifting came back, and i serviced the trans and found metal shrapnel. DD went down and I was forced to drive it everyday, it lasted two weeks then this........again. Same thing, broke on a wot 2/3 shift getting on the onramp. Rev limiter, all neutrals.

Have this beauty sitting here, fresh from the junkyard, and got lucky again, its been rebuilt.

Cant leave well enough alone...

The parts list: BTR stage3 truck cam, springs, pushrods, Melling 10295 oil pump, Cloyes LS2 chain/sprockets, Circle D converter (same spec as before), Nelson 80e adapter harness, 32 spline yoke, junkyard 80e, HD2 kit to be installed, Derale deep pan. No more 60e BS for me.

Interested to see what is needed to do a 2wd 4l80e swap. Nice work!

I figured it was a matter of time.

What's that, 2 or 3 4L80 swaps going on at the same time here?

 

[bigdog9191999]

I imagine the 2wd swap is easier than swapping from awd to a standard 4wd setup with the electric case, is why you went this way?

 

[01ssreda4]

I live in the south, no snow or inclement weather. The front diffs are notoriously bad on these trucks plus room to work is tight in the front. So ease of maintenance, less things to break that I don't need.

 

[01ssreda4]

Took the day to pull this SOB. Wonder if the scrap metal guy will take it?

New parts, more to come......

 

[01ssreda4]

Sold the old converter for $350, TCI pan for $120, and 4l60e for $50. Here's the pan shrapnel:

New Circle D, same spec as before, 3k/3200 stall speed.

Sometimes its the little things in life.....

$1 worth of purple power, $1 worth of spray paint, and the HD2 kit is installed and pan in on. Ready for install.

Here's what I came up with. I used what I had in the scrap pile which is just some Home Depot flat bar. I cut the old welded mount off where I converted to 2wd, figured the trans mount was now higher and further back. I measured the angle of the pinion and trans yoke and am shooting for 0 pinion angle at ride height. Couple junk welds with a Lincoln wire gun and it's in there. Im thinking the junk Anchor chinese trans mount will break before the bracket does. Time will tell. You can also see the Sonnax th400/4l80e 1330 yoke in this pic.

Now everything else is left, pin the front speed sensor, cooler lines, converter bolts, DS, dipstick, probably 16 quarts of trans fluid, etc...... Im thinking the Y pipe aint gonna fit either so that may have to be remade. But we are close and I'm excited just to see it in-place.

 

[01ssreda4]

Yoke fit great, th400/4l80e Sonnax 1330 full spline. And it has more slip then the 60e even though the 80e is about a half inch longer.

Segment swap from a 2004 HD, 12 quarts of fluid, pinned 22 and 23 for the input speed sensor, converter showed about .200 clearance so i added a 1/16th shim.

 

[live2pull]

Did you shorten the DS or have a new one made? A 2wd 80e swap is a desire when my 60e eventually goes, although, for a stock DD I am not sure it is worth it.

Same DS, with the Sonnax slip yoke I had even more clearance then the 60e

I cant seem to win with this truck. Randomly started getting some gear whine under load from the rear end (motive 4.10s, stock open diff). Pulled the plug and there was some shavings. I figured I dont like the 4.10s with the 4l80e gearing so lets upgrade right? Ordered up an Auburn posi and motive 4.56s. Did the install and didnt find anything obviously wrong inside the diff, super happy with the difference though, and it tamed the converter down some for driving and towing.

Now that that $700 is gone in the wind we are good right? Nope, truck has been running like crap lately. I had installed some flow matched decapped injectors due to the stock duty cycle hitting 130%. All seemed well for a few weeks then it went bad. Fearing a faulty injector I ordered up some flex fuel injectors and adapters. Installed them, started tuning and its running worse! Something mechanical must be wrong and i bet its something simple. Time for more digging.

Dammit. It’s always something seems like. At least it is for me.
