Broke something and need some help.

[87pickup]

Heres the deal i was starting to climb a fall and didnt really seem to be bound up but did have the dual ultimates in double low and all i hear is BANG! And now my truck wont move in forward or reverse. Im guessing a rear output shaft but i would imagine i would hear the 2 halves of the shaft hitting each other unless it was a straight break and maybe the 2 halves seperated a little. So what do you think? Output, Input maybe something in the tranny? Specs are
87pickup
3rz
r151f
23 spline dual ultimates
5.29's and locked

it doesnt move in any gear, 2wd, 4wd, high, low?

[TIMS89CRAWLER]

sounds like a rear case input shaft to me...

[86rustbucket]

just bang, no grinding,clanking,or nuthin?

[Tallchevy]

Drain some oil out of each t-case & the tranny. The metallic color or chunks of metal might tell you which case has the problem.

Doesnt move whatsoever. Everything shifts fine but doesnt move

just bang, no grinding,clanking,or nuthin?

nothing, thats what i thought was strange cause i hav heard of outputs breaking but they make some noise after. and mine didnt make a sound

X2 that should tell ya. Make sure to post up pic's of the carnage when you find out.

is it still out on the trail??

i'd bet its the tranny to tcase coupler

No metal chunks or flakes out of either t-case. Fluid was full and looked good.

Is there a way to check this prior to pulling the t-case?
Any other ways to check for the output being broken? If i remove the driveline and with the trans in gear will the output turn freely if broken?

[TIMS89CRAWLER]

anybody wanna put $50 on the 2nd case input? i have seen so many of these break with a single pop and nothing else... when gear oil was drained there were no metal chunks either just a clean broken shaft! thats the first place I would look unless your running 23 spline total splines then its a different story if its a stock input then i guarantee thats the issue.... let us know

[Rockcrawlintoy]

drop it all and check it out at least drop the cases.

I think its a 23 total spline Since they were built at Marlin and I think thats what they put in their 23 spline dual ultimates. I am going to pull the t-case's but wanted to order a output tomorrow if thats the problem and wont be able to pull the case's until i can get it to my dads to use the lift.

could it be somthing with the clutch?

I'd wait till I pulled the cases and checked them out, no sense in buying unnecessary parts.

[87pickup]

I will pull them asap but i just pulled the drivelines and the rear t case flange is movin around quite a bit. About up and down 1/4 in both directins and pulled out about 3/8 of an inch.

[*ROKTOY*]

Sounds like part of the problem.

[peacesells]

I bet its that output shaft man, definatley (was) the weakest link in your drivetrain. Id say order the long output monday if you have the cash. If youre pullin cases out anyways now is the time to put one in. By the way let me know if you need a hand pullin it apart.

[jonathan82toy]

I vote rear output shaft.    Pull it out and take some pictures then call me

Will do. Thanks Jon

[87pickup]

It broke about as clean and straight as it gets. No wonder there was no noise and no metal in the cases.

[jonathan82toy]

Nice!    If you want to ship that back here, I can get it back to you before MC8

[Steve_925]

looks like it was machined like that

[Rockcrawlintoy]

pretty standard. u goin cro mo

[87pickup]

pretty standard. u goin cro mo

Yea, I want the Marlin output but might not be available till after the round-up and if thats the case im gonna have to go longfield. Im letting Jon and Dave make that decision for me

[87pickup]

chromo output is on its way. Hope to have it back together next week.

[87pickup]

Actually Tara called my from Longfield today and said they are sold out on outputs but should have some next week.

[peacesells]

Joe, if you want to get your truck back together this week you can take my long output and give me yours when it comes in the mail. I dont think I will get a chance to put my tcase together for a few weeks.

[peacesells]
