Surprisingly, I'm starting to like the "grabby" feeling, it doesn't bother me nearly as much as I had expected. I am no longer dead set on removing the Detroit from the winter truck, and that's a 180* U-turn since my first winter test drive.

K10 gets an ass transplant

I just have to ask, no offence intended, but did you ever consider using a Truetrac? I know a guy who ran a pair of them in a TTB Bronco on 35's and they did amazing in that thing. I don't know how much hard core crawling you do in your truck but a Truetrac seems like it would be a great fit for you. In situations where he did lift two tires and wound up without power applied directly to all wheels, a touch of brake pedal locked them right up and he was on his way.
Curious how the wife feels about you getting some ass?

With my DD anytime it was wet on the pavement, I had to be really careful as she would do donuts very easy with a slight turn of the wheel.

Not sure if you were directing that to me or others, but I have a TrueTrac in the front of my Polar Bear Suburban and love it. In fact, that TrueTrac went into the K10 years ago at the same time the Detroit went in the rear (one of those 4WP package deals) but a few years ago the K10 gained a front Dana 60 and the Burb inherited the TrueTrac’d D44. I would like to throw a TrueTrac in the back of the Burb someday too for the off-road it sees.
That said, I want more than a limited slip in the K10 as it does get into some pretty hairy stuff where I want it to lock right now rather than slip a tire in order to get it to lock. Look up my Youtube videos sometime.

Hehe, not sure if she even knows…..or cares. What happens in the shop stays in the shop. Well, except for you guys.

I read through here in great interest because I built a lot of these differentials in the past and just had one last summer here where I'm retired.
That the vehicles get a 'shimmy-turn' or a 'click-pop' noise and the rear end moves sideways was always a sign that the oil in use in the differential was OK, but missing an important ingredient.
I had a '73 El Camino, 350 SB, factory 4 sp, no A/C, just PS and PB.
It had a 4:10 Posi rear, factory dual no-cat exhaust 4" system all the way back with no cats as they were an option in those days even in California.
I put on Dual Q-Jets remounted on a 1969 Camaro Z28 X-over manifold.
With 13:1 compression ratio, Mallory Dual Point Distributor, Chet Herbert solid roller cam, etc I had to run 120 Octane (the old octane method number, not this new fake numbering system).
But the biggest problem it ever gave me - besides a couple of pursuits that I won (and the statute of limitations is 'way gone by now!) was that the GM Posi-Traction additive died at regular intervals and needed refreshment to keep the diff from alternately grabbing and releasing.
After making 20 right turns and 20 left turns in a parking lot one day so I could travel on for a while until the clutches either squeezed the additive out of the plates or whatever - well, it was embarrassing! I did that in The Tyler Mall off the 91 FWY in Riverside CA., and I scared small children and old ladies and hurriedly got out of the lot before the security cops got there.
But by getting it back to the shop in Santa Ana and replacing the lube with Castrol 85/120 EPW and a bottle of GM Posi additive, it was good for a year or so.
Depends on how hard I pressed it - but after one night at the drags, I'd have to change the fluid before I could drive it home again.

Joe, the additive makes sense with a posi. Detroits don't need any additive like the clutch type posi does. Interesting story though..

I'm not thoroughly knowledgeable about the Detroits, as you can see.
This begs another question: I'm self-convinced that having any sort of Posi- or Detroit Locker is best on the front axle of a 4WD.
When I get into deep snow - or in trouble - or IN trouble IN deep snow - I put my chains on the front axle tires and I can get 'pulled out' by the front tires/chains instead of being 'driven out' of a ditch, etc.
I like the chains in front so I can steer where I'm pointing and where I want instead of hoping I can steer while the rear end gets bite and pushes me where it wants me to go. RIGHT?
This has worked well for me both here in these multiple small winter Montana snows, and in those 4 foot snows in Idyllwild, CA.
Having watched and ridden in Larry's K10, with the Detroit, the truck was pretty unstoppable. In most cases, just because of the locker he could do many obstacles in 2wd with the traction from the rear being enough to get the truck through. The trade off as Larry's noted many times before of being fully locked finally got to him. Going selectible will allow him to be locked up when needed and open the rest of the time. Thereby saving his sanity on long road days to the desert.
It was and I should have addressed you directly I guess to clarify that, my bad!
Got a link to your channel? I'd LOVE to see your videos.
In snow, with a solid front axle, I have always chained the front first. Don't do that with an IFS rig.. saw some people learn that the hard way.
Carry on Larry!
Carry on Larry!
When I was running a wreck, I pulled out a couple of trucks that had blown the front diff from just having the front only chained up. Both were offroad in lots of snow.
I've ran chains on the front wheels of my Tahoe several times, on road in deep snow though.
Chains...Meh. The right set of tires, aired down and mine goes everywhere to guys that chain up with us go. No worry of a chain coming off and wiping out a brake line.
I personally haven't seen that work with a 3/4 ton or bigger with a load.
A side note, the 6x6 Autocar would do lots of stuff with chains on all of the tires!
Sorry for the further derailment Larry,
But I should have clarified, both trucks had something go wrong with the front axle, t-case was good.
Loaded, 4 low, chains on just the front.

Hehe, no problem. When nobody else responded I figured you were talking to me.
. For some reason, I thought I had Youtube linked here. Must have lost it when the new format came to be last year. Anyway… Here is my Youtube channel. If you click over on Playlist all the Desert Trip videos will be grouped together. This is always a fun one to watch….
As far as chains...yeah, Rob and are in the same camp on this one where I am not a fan of tire chains either. A couple of the guys we go snow wheeling with like to use them and it seems they are always fiddling with loose chains or pissed off when a chain slaps their vehicle when it flies loose. For the deep stuff, I just love the Super Swamper TSL Q78’s. They tear right through snow like nothing…. The DuraTracs do a fine job but Swampers do it so much better
Have you made an assessment on the wider rear end?

Did you just ask @Larry if he had a fat azz?
