How do you get the old drive pins out of the CVD bone? With a hammer?

I'm thinking of getting a set of the composites with the cushions pre-installed for the rears. How would those hold up in 19 turn rubber?

You can try grabbing them with a bench vice or vise grips and twisting them out.....but if their real tough, like some of the ones Iv'e experienced on the thicker aluminum CVD's that come on the TC-4......You can drill a whole slightly bigger than the size of the pin (all the way through) an old plastic screwdriver handle......lay the CVD flat against the screwdriver handle with one half of the pin in the hole.....and take a hammer and pound the pin into the hole in the screwdriver handle...at this point you can usually twist the pin out with vise grips.......Niftech sells a little device that basicaly does what the screwdriver handle does here.......and the composite CVD's hold up ok in 19 turn rubber but they do flex slightly.... (IMO) making the car feel to soft comming out of tight corners compared to the aluminum ones

BlackKat: youd be better off picking up the dogbones with the pins already installed, like the IRS ones. Switching from the metal pins to the cushioned pins is a pain in the ass, and sometimes they want to come out. Seriouly, save some time and buy a set, youll thank yourself. Especially if you try to get the metal pin out of the aluminum dogbone.

Bob Barry: I explained everything youd need to switch to the TC3 driveshaft in my last post that was directed towards you....... . You need the drive cups from the TC3.

Blackkat-
Do not use a hammer to drive the pin out. You will mushroom the pin on the end, and when it goes thru the CVD, it will make the hole in the CVD larger. Then you will have a hard time getting any type of pin to stay in place. Use a punch to drive the pin out. Be sure it is smaller than the pin so it won't open up the hole.

Its a pretty easy swap to go to the TC3 shaft....took me like 10 min.

Seriously though BlackKat.....Just buy the shafts with the cushion installed unless you already have the cushions. Its a difficult task and really isnt worth the effort.

Sorry Bob. As MikeDeadly said, it will fit but you will either have to replace the input cups or the pins in the driveshaft. I, personally, would NOT change out the input cups. They were beefed up to prevent them from blowing out...a somewhat common problem in the TC3.

TPhalen: Can you think of a way to enlarge the slots in the TC4 drive cups? or would that weaken them back to where the TC3's cups are? Ive personally had no problems with breaking drive cups, even with a 9turn, but in case I ever need to replace them I wouldnt want to have to track down a set of TC3 drive cups.
What would you suggest then?

I think I'll (eventually) just do that. But how about these http://www.speedtechrc.com/store/ebp...id=326&id=5252

Lightweight TC3 driveshafts...right here

That Speedway PAL stuff looks pretty sharp, but i think you need to buy the outdrives and the blades together. Those blades only work with thier outdrives. And as far as the driveshafts go, you really cant get any lighter than carbon fiber...

If they don't fit my outdrives couldn't I just file them down a bit?

you would need to remove quite a bit of material ...and if they are not filed straight... . . .you might get a seriously wobble from the Dogbone

JDM: I have the IRS aluminum outdrives. Do you have a set you could check the blades against?

So...you guys are having problems with the stock plastic diff outdrives? I've never had a problem with them on the TC3. Is is because of the new, beefier bones putting more of a stress of the diff or what? Are they fronts because of impacts or both because of stress? Ifs its because of impacts...I got my PDub bumper comming
