Why the love affair with 26 spline input shafts?

    Putting off a clutch to install an input shaft is rediculous. If you can't afford both you are already in over your head financially. Not to mention you are going past the clutch to get to the shaft. :poke:

    You are very different than most people. Most people want to fix the problem part once and enjoy the car, not continually replacing the same deficient component. I HATE working on my car and bikes, I much rather be piloting them. Some people don't work on their own cars so replacing the input shaft 14 times would far outweigh the cost of a 26 spline in labor.

    Wow....you haven't listened too well. But I do agree with you on one thing: You are indeed different than most people.

    As others have said, when the 10 spline input shaft breaks, it often takes other parts with it including throwout bearings, TOB retainer sleeves, clutch discs, pressure plates, flywheels, and internal transmisison parts. And I've never heard of it occuring in front of the owners house where he can just push the car into the driveway, jack it up, and fix it lickity split. Generally requires a tow.

    I guess an IRS brace is just "piece of mind" too???? Gotta pay to play with these cars and if you're into aggressive street or track driving, it may actually save you money, but certainly aggravation, to go with a 26 spline shaft.

    But if you insist, I will gladly sell you my old 10 spline for $10 plus $10 for shipping, which would save you another $30. Then I'd have to go out and find a new paper weight though......

    There you go, OP! Now you have nothing to bitch about! You can just buy his old shaft so you have a cheap replacement when yours finally breaks!:idea:

    Parts break. When they break why not upgrade? If it's a money issue, then maybe you shouldn't have gotten into this kind of car to begin with. It's cheap and easy to make power in these cars. That means that the driveline parts will be getting a good workout. If you are hard on those parts, then something will eventually break. I personally have always been one to upgrade broken parts, but I guess that makes me stupid.

    Those ten spline shafts are probably breaking from the wheel hop hammering the drive train not sheer power

    torque. Pure torque will do that. I've twisted the pinion in a 9in rear in my bronco with just torque. Most people know what to do when you get wheel hop. Not saying it doesn't contribute to the problem but never heard of one breaking from wheelhop.

    I think you guys are missing my point. It's not a must have, it's nice to have and it is piece of mind. but there is no reason to put off getting a clutch so you can enjoy driving you car just for piece of mind. have you ever driven a car with a slipping clutch? it's not fun because you can't get on it you, can't even put it in 6th gear and touch the gas.

    there were over 19,000 of these cars made and even if 500 people have broken input shaft thats like 2.6% or maybe 1000 thats 5.2%. I like the odds that it's not gonna break.

    the only difference that I am aware of is the splines are longer on the D&D. I have had both and no issues with either and have installed liberty's for the most part.

    Do you need the longer splines on a twin disc app?

    When you are already spending the weekend pulling the trans out, spending $600 on a clutch that you likely won't need to replace again any time soon, pulling the trans apart for the forged retainer for another $100+, you already have the trans out on the table and need to re-shim it already anyway, and you're talking $250 more for something that takes 5 seconds to swap along the way, for something you will never have to touch or worry about ever again... why not? Or spend $600 on a 10 spline clutch that you're stuck with and then spend another $600 on a 26 spline clutch if and when you do need it?

    In the words of Coletti "Put the gold-plated part in there"

    Anyone who whines about the extra $250 for the input shaft as preventative maintenance on a car that requires $1000 in tires every 6-12 months needs to get another hobby and drive a Prius.

    Now blowing $1500 on axles you don't need until you start breaking them AFTER bushing overhaul? Completely agree. Input shaft which is mere $250 more one time cost to a clutch job, which is part of a system and future upgrades for the life of the car depend on your choices early on (eg: spline count), go for it.

    That said, when I get around to investigating my clunk this winter, I may be springing for those forged chromoly CVs if they end up being part of the culprit. Not because I need or want the strength, or worry about breaking the stocks, but for the tighter clearance and less play in my drive line slamming my drive shaft back and forth and giving it a seizure between drive and coast any time I lift or shift or putt along at low speeds in parking lots. That shit is going to snick and click like a Rolex or Colt Python when I'm done with it.

    Wow it's been a long time since I did mine, they are $350 not $250, but my principle remains the same.

    LOL @ paperweight 10 spline input shafts. I keep one on my work bench for that specific purpose.

    There has never been a question of me upgrading to 26-spline.

    I was just debating on changing out the half shafts. Typically, when do half shafts break? Is it during a high RPM lauch or slamming through the gears...say on street tires?
