if you are planning to get a detroit anyway the carrier difference makes no difference for you.

Guess I didn't explain it fully

I'd swap out that pinion yoke for a full flanged one so you're not relying on those u-bolt straps as they'll snap easy. I had my aftermarket shaft flanges reamed for cone washers, just like the factory one's. I have a new (installed but never run) low case Detroit for 30 spline if you're interested.....

Sputnik40 · 05-03-08, 12:44 PM

I'd be interested in the Detroit if I could build it with 4.56 - not sure what low carrier means, but guessing it's the opposite of high pinion? Can't commit to anything until after GSMTR. Not knowing what I might break - won't do me any good to have a half pieced together rear axle and be broke...

Definitely will be going with a flange - will be running my mini-CV shaft for a while - and then since I already have a 1350 CV flange on the Orion - will upgrade later. After so much rear axle breakage - kinda looking forward to maybe having a driveshaft weak link...

Back at it - fawking near 90 out, painting my sons Westfalia bumpers in polyurethane, putting the axles back together and just finished chopping some square tube to make a rock ram mount.

LC_Hamma · 05-03-08, 01:41 PM

Low case = low gear carrier

I'm only using the 30 spliner cuz I don't plan on runnin any larger tire than what I have on it now. If you think 42's are in your future, go for the 35 spline for sure. Then, you'd need to clearance your spindles & get a 35 spline Detroit, which are always in the for sale section on the PBB.

Mace · 05-03-08, 03:32 PM

If I were you, I would pull that axle apart.

It might already be 35 spline.

If you get Big Bearing 9" ends you can shorten that 60 to whatever WMS you want and run SF six lug 35 spline shafts ..

If the inner shafts are 30 spline, you are not upgrading axle shafts much at all over the poly stuff.

peesalot · 05-03-08, 07:15 PM

them 3 " wheel spacers are bending those shafts. you prolly run 2 " bs rims ontop of those spacers huh ?

wngrog · 05-03-08, 07:56 PM

I hate to agree with anyone that runs Groundhawgs.......but Pees may be on to something here...

TURNMEOVER · 05-03-08, 10:19 PM

Ok I have been following bills thread here and the whole spacer thing gave me some hope. I plan on 38.5 x 12.50 tsl bias . I will have the same drive line as bill and . I need to run atleast A 1" spacer to clear the front calipers. Do you fell this will be ok or should I step down to 36 or 37 " tires ?

peesalot · 05-04-08, 12:24 AM

Well, I dunno but I know I run 1.5" spacers on poly rears with 15 x 10 rims with 2.5" of bs and have hopped the hell outa 37's with no breaks. To be fair I also have not had the axle apart to see if the poly rears are showing any signs of twist or spline issues. IMO a 38" tire alone , you are o.k., a 38 plus 3 " spacer + alot of bs = time for a ff axle.

Hawgs are gone, waiting till I can get a 39" sticky Hawg then they be back.

baxter650 · 05-04-08, 04:12 PM

The Poly axles that you all are breaking, are they semi or full floaters?
And just what does Mr Long do to his axles that makes them so tough?

who knows it is classified.

baxter650 · 05-04-08, 06:38 PM

I am curious, has anyone broken a full float Poly axle?

Aaaaaaa nope - gonna disagree with you on this one. Am running 2" spacers with WE beadlocks that have something like 4.5" of backspacing - that puts me at about 2" or 2.5" backspacing (which is what, about an 1" past normal?). I ran Stazwork double beadlocks at 2" BS with 38.5" TSL/SX's siped and air downed all the time with no real issues. Went to the WE's when I wanted to go 39" after reading all the junk on Pirate about improving steering while aired down.

I think the Poly's must max out at 37"s - which to me isn't all that impressive compared to stock - but then again, I am really not a big wheeler - only getting out for about two runs to Tellico and 3 or 4 runs with NF Cruiserheads annually. Really rely on folks like ya'all who live out West and live/breath wheeling all the time!

Just strange as I know of several folks running centered mini axles that are taking a bigger beating that I'm dishing out - especially considering my nursing it a bit more lately.

Not jealous - as my friends put it, life isn't so bad down here

R.K. · 05-05-08, 06:54 AM

Damn Bill, you Florida guys are rough on rear axle shafts! How many have you and Jim combined to break now?

Get that thing back together so you can ride with us next week at the GSMTR. We'll be there from Wednesday through Sunday at the Tellico Cabins right on Trail 1. Should be 5 or 6 rigs there with us.

Hahaha! You're absolutely right... I need to do a bunch of research and ask lots of stupid questions before I settle on an answer, but I liked your prior 35 spline suggestion.

The rear is back together - pulled apart a spare rear axle to harvest the axles for spares, bringing the spare no-slip and another 4.56 chunk (as well as some spare mini-shaft parts). Heck gonna bring a spare spring too!

Bit more stuff to finish - but plan to load on the trailer this Friday and head for the UC meeting on Saturday and some chilling in the Upstate, then over to State Line Sunday night. Definitely plan on catching up to you to see your new mods - if possible, let me know if Steve (Eric's old chopped FJ60) and I can join ya'all for a run or two.

mookie · 05-05-08, 09:48 AM

are you running red label crawlers? i'm thinking that toyota rear axles just aren't strong enough to survive sticky tires.....one of my buds fragged his rear dana 60 ring gear after he swapped to crawlers....

i wonder if Mr. Longfield would heat treat & cryo stock rear axle shafts if you sent them to him? (he treats r&p now if you send yours to him).....i bet they would be stronger than poly's shafts...

lowtideride · 05-05-08, 10:40 AM

I almost wonder if you are better putting stock shafts back in.

Not sure if those were the 30 spliners or if it had the spindles large enough to house 1.5" dia. shafts....

30 splines as same as Yota stuff .. but I never thought in a D60 ( even offset coz are SF ) for my Tencha .. my option should be a FF Yota rear or if I gotta go to 42" - 44" 14B FF Corporate ..

Lots off cut ..

Bill if you need more spares I have 2 spare sets of rears and 2 spare sets of fine spline front mini truck birfs and shafts . Drop me a pm on nf .

bad mudda · 05-06-08, 02:30 AM

I have stock 33 spline G,Q axle's under my 45 runing 37'' tyre's with v8 and have bounced the crap out of it on a fair few occasion's and have not yet broken one, i have spare's to put in but i'm looking at getting chromo axle's/c,v from Cal offroad there the stongest i've heard of so far.

Do you have any proof, or is just anecdotal?

Excuse my ignorance - but what axles do you have? I'm not up on the "G, Q" acronym? I did fine on 37"s and pretty decent with 38.5's - it's the 39's that are killing the axles (mind you the other tires wern't killing stock axles - only 1 in 7 years of hard wheeling with 35 Boggers, 37 MTRs or 38.5 TSL/SX's).

The Poly's just aren't taking the leverage/torque on the designed principal of twist - they're a twisting and bending - and then staying bent apparently.
