2005 Bulletproof Taco: 1 Ton SAC

Joe in his fj80 would probibly come out for that as well. 2" of lift, 40s, some funky radius arm suspension going on up front.

 

We still need to make a new front bumper THOON.

 

The ginger is excited about wheeling again since he swapped in an FJ60 front and an FZJ80 rear axle on the 4Runner

 

I'm either going to hit Harlan or Flat Nasty this fall for a long weekend and could come for this one. Problem is that I love how close all the trails are together at flat nasty

 

Maybe it's just the video distorting it but the new muffler you put in sounds pretty deep

 

Im the opposite, i love how spreadout harlan is, it feels like your actually going somewhere!

 

Flat nasty is fun. @ChandlerDOOM and I have been a couple times now

 

Mark, hope you don't mind if I throw a few more pictures in your thread for you

 

Not at all...the more the better!

And I snapped my tcase output tonight at the truck pulls...launched just a tad to hard lol

 

Well folks she's a crawler not a puller...

 

If you want to PM me your details and I'll see if I can get one for you. I sell used parts

 

Well last Friday afternoon I busted hump to get bumpstop extensions done (to save my springs) and a weight bar made up front, and got to the pulls with plenty of time to spare. After getting tech'd in a found a nice spot to park:



There was a stock gas, stock diesel, and run what you brung class, all had to be street legal no trailers. Patiently waitng my turn:



Well my turn came soon enough and went quick enough. Since this was a floating finish distance was all that mattered so I figured I would give L-L a shot. Bad move. Major Mistake. Epic Fail. Call it what you wish. I gassed it off the line to a large whoo-POW which I figured was something important but the sled was moving now. 75' later I called it and looked under the truck to see my rear output gone.



Luckily the exhaust, shackle from the traction bar, and the horsecollar crossmember acted like a driveshaft hoop and kept it out of things while I drove to the pits. I removed the rear driveshaft and drove home front wheel drive.

Cracked the case open and gutted it:



Stuck some new guts in:



All back together now and ready for V6 mud drags Thursday at the Fair

The offending shaft:

 

I'm surprised at how clean that break is.

 

Shear point?

 

Yes, but I would assume grain structure would be running lengthwise leaving some amount of deformity, spiraling, or multiple pieces. So clean, it almost looks machined off.

 

Mark, if you post a picture of the shaft looking straight on at the break I can probably tell you why it failed. We had a training at work to be able to determine how and why things break.

 

I can, but it was right at a stress riser due to a notch machined in it for some reason. I will get more this afternoon for you all.

Oh...drove the truck to work today I get knocked down...but I get up again

 

Long overdue as usual.

Damn, awesome action pics!

Rig looks great!

 

As usual, pictures never do it justice. Even so, the rig and Mark's driving don't need ridiculous camera angles/tricks to make it look steeper.
