10 bolt to 14 Bolt, 9.5 sf swap

[randeez]

So mech and I were trying to make sure we had the correct ujoint. He had a 1310 to 1350 one. Compared it, it definitely looked like both , the stock driveshaft and 8.6 yoke, were 1350. He called a few places. Couldn't confirm, said f it and pulled the stock driveshaft out and set it in the 14bolt yoke as it sits, just needs straps.
Soooo as a side note, the 10 bolt 8.6" I have now, has a 1350 yoke on it

My driveshaft still looks like hell I will get a built and balance aluminum one anyway

Pulled some PN#, not sure they're right.

Been scratching my head about it for a few weeks. ive got a 1350 to 1310 and a 1350 to mechanics 3R conversion joints, that's why we finally just pulled the driveshaft and set it in the 14 bolt yoke.

The smaller ujoints all have inner clips to keep the caps on. Mine just has outer clips on the driveshaft and tab/strap on the yoke

I keep coming up with a 23104840 for the u-joint on the 9.5, same as our front. Our rear u-joint is 89059111, a 1350. The 23104840 crosses to a S-44 and 5-795X.

I've been working on the yoke and slip yoke and driveshaft numbers as well. Have to stop as my back is really acting up now and pain meds are kicking in.

/\ i keep chasing my tail on it bud, i'll see if theres a physical part no on ujoint when we install it. but right now i'm convinced the stock ujoint that is in there now is going to work fine

welp, kinda uneventful. everything swapped right over to it.
brakes - caliper brackets, calipers, pads, hardlines just needed to be massaged a little over the pumpkin.
5 links bolted right up- uppers/lowers/panhard. panhard is very close to the stock cover on the 14bolt, may not be able to use cover with spoon adjustable
shocks mounts exactly the same with belltech extenders worked perfect.
and driveshaft already had correct u-joint from my 10bolt.

That's awesome, going to do that to mine someday too. Have you thought about putting in a 4x4 transfer case like the MP3024 from the 2500s?

if I ever kill it dont know... I am probably one of the few that enjoys just having full time awd. If i get to the point where it simply wont handle what i throw at it then sure, but i would probably just go 2wd before.

old 10 bolt atleast needed axle bearings/seals, wasn't much slop in the carrier but still happy all went smooth took 3-4 hours for the swap from the time i drove in till the time i drove out

I thought the other case might allow you to run even faster besides giving your more options. Glad it worked out just fine. Gonna keep the old one for a spare or sell it off on CL?

it's kind of "payment" for helping with the swap he is going to hang onto it, has a single cab he wants to 4link. he may eventually do a 14bolt for it but mocking it up with the 10b will make for an easy upgrade later.
