Who's Broken???

[FELIX]

Just curious, Who if anyone has actually broken a stock main shaft, or a correctly (centered) hack & tap in a 231?
What was the factors, tire size, heavy on the gas, size lift,mud,sand,rocks, ect.

thanks.

Yes. 2 of them.

2000 XJ, AW4, 231, 4.0L, 4.56's, ARB's, 33's



Both were with the RE Hack 'n Tap kit and on rocks

I have broken it. I was on 35s and was givin it all she had.

Spring wrap? and bottomed out U joints? would one be correct in assuming that that is the main culprit?

I have run one for years,if I had a clue how to post video I'd show you what giving one "hell" is, never broken it. Broke three t-cases , not at the shaft, removed the hack and tap and installed on the next victim. This is with 38.5s and a stroker motor.

havnt broken mine in almost a year of decent use.

i broke one. axle wrap is my guess.

DC has teh HD SYE's for $170 delivered right now. i'd jump on that one.

I have been running one for about 3-4 yeaars now and have not had one problem. I run 4.88 gears with detriot lockers and 33's. And I do run her hard thur the trails and rocks, don't like sand. Axel-wrap or like you said bottom-out u-joint. There is a new u-joint on the market called the (Cheater Joint/Super Flex Joint). It's made by Tom Woods Drive Shafts and it comes in both 1310 and 1350 series. The design of the off-set trunnions sets the the yokes further apart then the conventional joints. It's suppose to allow for a 10 degree more flexibility then the standards joints, which they say a 5" more droop before it binds... The next set of joints that I have to replace, I will try them out. If anyone has them allready, Please post up your opinions.

Hey guys, Thanks. Yeah I have had a RE hack & tap for about 7 or 8 years w/ No problems. I was just currious on how many have suffered broken shafts, if it was really common, or like putting a man on the moon, very seldom. I'm not real hard on my truck, but it does get used. I recently added a 4:1, & was wondering if the extra torque might be a factor. I run smaller tires, 32x11.5's which have taken me everywhere I've wanted to go, locked in rear, & true tracked front{soon to be locked}

Thanks, & we'll see if the list gets bigger.

Not a 231 but a 242 - murdered when I still had 33's

running numerically higher gears in your axles will reduce the torque load on your main shaft.

thats why running bigger tires on stock gears is unwise.
