well i took my dart racing last nite for the frist time this year and on the 12 pass i broke the tail shaft into.which let me say is the frist time i have ever done that.So i am looking for answers why so i dont do it again. i have used this shaft before with no problems. but last year i broke my 8-3/4.locked the rearend going into second gear at the track.the drive shaft never left the car etc. but when the rear let go it shook the car pretty hard.i took the trans apart to check the sprag etc and ever thing looked fine.so i put it back togeather.also had a 1350 end put on my frive shaft and had the shop check to make sure the drive shaft was not bent.he said it tesetd fine. so last nite on my last pass i did a biger burnt out for the stands. the car launched very hard and i was off.the car ran great no vibraions etc. so i get back to my pit stop and the girl friend comes running up thinking i blew up the engine. i say no and ask why. she said as soon as i took of there was a lot of smoke coming out from under the car. so i start checking and thats when i see the broken tail shaft.
so my question is what caused the tail shaft to break? i mean what should i look for? also i have another tail shaft. should i just put another on on and drive on or should i pull the out put shaft out and have it checked or just build another trans? the clutches etc still looked brand new the last time i had the trans apart. which only has about 15 passes on it. here is a pic of the broken tailshaft.thanks Mopar65

ONE(or a combo) of these three things(IMO) ... bent D-shaft, bent output shaft and/or you damaged the bushing in the tail housing and the D-shaft yoke is wiggling-around and causing enough vibes to break the TSH.

All the above plus you could have cracked the tail shaft from the previous diff failure and didn't notice it. You gotta start from square one and check it all.

I think when you took out the rear it cracked the tail,
since you said the drive shaft is fine and you dont have
any vibrations.... I'm thinking you never looked to
see if it was cracked.... then add a few more launches
and.... you know

thanks for the info guys. I am pretty sure i checked everything over.but maybe i missed the tail shaft. so do you guys think i could just install a new tail shaft and be ok? the car did drive on the trailer under its own power and i was running around 125-126 mph in the 1/4 last nite? thanks bobby

ALL cars flex its just a mater of how much... I think
the car flex took it out.... even with the rubber mount...
and being NEW its stiffer than a old one..... JMO

Have a driveshaft shop check the shaft on a lathe, the same thing happened to me last year, I broke the 8 3/4 off the line the car shook bad, after that I was cracking the tail shafts every other time I took the car out, car did not seam to vibrate down track, I finally took the shaft to a shop and he said it was bowed in too places, you couldn't see it turning it in the car with a straight edge, after changing the shaft I never broke another tail housing.

When my diff broke it did cause the tail shaft to break in about the same place. It was on the launch off a T brake so it was instant and a little more violent then yours was.

I would suspect that yours was cracked when your diff broke then just took a little longer for it to come apart.

FWIW, my output shaft was OK and just needed a new tail shaft housing but definitely get your checked.

Mine broke in almost the same spot a few years ago after I swapped trannies. Turned out that the output shaft was bent. How the heck did that happen?

They all break in the same place... through the speedo
hole... its just the weak point of the tail shaft...
its a matter of what causes it... I have a buddy that
has a quick car that went through 3 tail shafts in
4 weekends... his was a bit different but he has a
front plate, mid plate and he was running a solid trans
mount... I told him the first time to get rid of the
solid trans mount... he didnt... then after the third
he finally did... since then its been fine.... you
cant tell how much flex a car will have

sometimes it hard to say what broke yours?
i know of allot of them that racers i personaly know , and race with have broken so many and with diffrent trans in same day
that now they carry couple as spares,
now for me , i have never broke a 1 not a single one ,,
one can blame a previous breakage, etc, i have even heard that tires being out of balance will do it to? ring pinion gears , lose pinion nut,,
so i wouldnt say could be all the above,
i waiting for someone to mount a camera on that area, and look n see what type of flex is going on in that area during launch and
de-accelleration, and what type of forward/rearward movement get involved as well, during a run?
just a thought

Your big burnout could have did it. That's what broke mine. You had several runs then bang it's broke.
A driveshaft that's too long will do it as well.

Did you shortin the shaft when you went to the Dana?

thanks for the replys guys.I am still runing the 8-3/4 in my dart. dont have the money for the dana yet.I am running the 318 to big block coversion motor mounts and the stock tansmission mount.I will have to check to make sure. but i think i have over a inch of the yolk sticking out of the tail shaft.how much are you soposed to have? i know stuff breaks but this is a frist for me.yes i would like to find one out of a van or a truck. i have heard they are stronger.I have another tail shaft i am going to put on it.for no so at least i can move it off the shop floor if i need to and have to wash all the trans fluid off the bottom of the car.i might just find another trans to build up and use this one for spare parts. or if you guys think i will be ok to just put a new tail shaft on this one and try it again?thanks Mopar65

Should only have 3/4" on the drive shaft length...
so bottoming out sure wasnt the problem

When mine broke I went through the trans to check everything and it was all good so I put a new tail housing on and let er rip.

I agree, Looks like all the weight is smashing it down almost grounded to the bolt going through it.

That could be it. If its a motor plate car, its putting stress everywhere.

Well since no one answered your question as to what caused it, I will tell you what caused mine to break.
The rear end twist's up when applying torque to it.
In my case I didn't have a pinion snubber or traction bars,also weak leaf springs.
This allowed the rear to twist enough that the drive shaft would break the tail shaft housing because of the mis-alignment. Example( put a long pole on the tail shaft and lift up ..snap)
Do you have a snubber? how far from the floor pan is it?
Hope this helps, and yes go back through the trans. just to be safe.

x 22 on eye-balling the rear mount ... but the few failures I have seen in that area have shown clunking and thumping sounds.

ok i try to answer it,
i think he left so hard that the trans fluid filled the tailshaft up, and with the rotation of the rear shaft it build up pressure, and it had no way to vent the pressure so it had to break the rear case!!
hahhah lol

I thought if you ran solid engine mounts you had to have a solid trans mount?

I sure wouldnt... reason why is flex in the car...
if you have 2 points solid (now thats a straight line)
it can pivot BUT if you have a front plate, mid plate
and a solid trans mount, now you have 3 points which
doesnt mean its still a straight line, specially when
you induce flex... I always use a rubber trans mount
and I have never broke a tail shaft.... some guys
use the solid trans mount as a engine limiter... I
prefer to put a engine limiter on the engine(I happen
to use 2 of them)

No i asm not running a snumber and i have poly motor mounts.I am going to put a new tail shaft on it tomarrow and remeasure to make sure my drive shaft is not to long. is there a way to measure the out put shaft for straightness with out taking the trans out of the car? If not so be it i might just pull the trans.also at 125 mph in the 1/4 the car was smooth. i mean no vibration that i could tell or fill. could the drive shaft be bent enough not to fill it under power but enough to do what it did. the machine shop that change the rear joint to the 1350 said the drive shaft tested out fine.I think i am going to get a new poly trans mount for the car.i will put it back togeather and will let every one know how it does.thanks mopar65

no, u can't check the output shaft in the trans. i would disassemble the trans. have the shaft checked for straightness. as mr.p stated, make sure ur drive shaft is in the rear bushing deep enough & replace the bushing too. stay safe, seeya.

With mulitable good answers on this post, I'm going to throw my in the mix.

1. you see the shaft and the cast aluminum is almost completely sheered off in a complete circle.
2. stress from the axle twist in the upward movment pulling the drive shaft out of the trans as the motor is twisting the tork monster.
3. Time for a front plate, or solid mounts.
4. Poloy mount on the trans.
5. Snubber on the twisting 8 3/4

I have see a friend break his tale shaft in the speed "O" area and he locked up his trans and hurt the 8 3/4 to the ponit of putting in a Dana, and 2500 dollar trans.

Have that DS checked again. When I broke mine it was "supposedly" good too. Brand new from Mancinis balanced and all.

After it took out the tailshaft housing I took my shaft to a GOOD DS shop (Dynotech) not only was my "NEW" DS not balanced worth a damn, it was bent like a banana.

Just to clarify the wording a bit more here. You pushed the yoke into the tailshaft all the way and then pulled it out 1 inch for clearance? As Mr P had said, it needs 3/4 inch to travel. not 1 inch sticking out. If you didn't have this travel, it will bind and break. Many a person has fallen to this mis hap before.

We had our first break like that in a car with elephant ears, stock trans mount, etc and when we finally welded in a limiter to control fore and aft movement of the engine it never happened again--just my 2 cents worth--good luck getting her fixed

Exactly the same thing happened to me. I bought a really good (expensive) driveshaft. Second run, broke the tail housing. Sent the driveshaft to a driveline shop, and it was bent, and poorly balanced. They rebalanced and straightened it, no more problem.

Thank you SuperScamp for agreeing with my post.
I have seen several break from this happening,including my own.
It will keep happening too unless you limit the twisting of the rear end.(either install a snubber or some sort of traction bars.)
I have Calvert mono-leafs and Caltrac bars on my Demon.
I seen some beat up driveshafts that didn't hurt anything.
Good luck.

I thought if you ran solid engine mounts you had to have a solid trans mount?




I sure wouldnt... reason why is flex in the car...
if you have 2 points solid (now thats a straight line)
it can pivot BUT if you have a front plate, mid plate
and a solid trans mount, now you have 3 points which
doesnt mean its still a straight line, specially when
you induce flex... I always use a rubber trans mount
and I have never broke a tail shaft.... some guys
use the solid trans mount as a engine limiter... I
prefer to put a engine limiter on the engine(I happen
to use 2 of them)





Solid mount the engine...but never solid mount the trans...use the Poly bushings.
Something needs to give a bit.
