Topic: CV rear driveshaft

[4x4fiend]

Who runs a cv shaft on the rear after doing a dual case setup. my t-case end joint is at a pretty horrific angle, and is giving me a lot of vibes. This is with two regular u-joints.

[Fearofrunner]

I run the CV and have little to no vibration... It's a tom woods shaft

[cam011]

I run them front and rear, smooth as glass. Didn't realize I had driveline vibes until I put the CV in the rear actually. Let me know if you want to check it out sometime.

I run a tom woods one also, no vibes but keep fresh grease in there as much as possible

[WHITE_TRASH]

Im running a 94 cv in the rear with no vibes.  It was built by a local tractor shop .188" DOM 58ish" long....  Its a big sumbiotch.  I greased it when I put it in 4 years ago.....

the paint on your truck keeps everything alive and happy lol

You have NO idea.....   Wife started painting it when I was home yesterday....  All I can say is WTF was I thinking...

You can get a 96-02 taco/4Runner rear shaft from a junkyared, they have a cv built into them from the factory.  Then just get it cut to length.

I've got an old front shaft with the later type, lower deflection, cv. either gonna try that or get a used cv rear shaft and cut it down, whichever is cheaper.
Cam01 i'll pm ya.

what kidna problems (if any) do you run into with the cv hitting the horsecollar crossmember

[bigarms23]

I now have no vibration i am running a tom woods shaft in front and a je reel shaft in back and am happy both shafts have 17inches of travel

I got one too.  Taco CV from High angle driveline.  188 wall. 

No way I'd run a stock tube if you ever plan on visiting rocks.  (if you drive to/from the trails)

Tom Woods CV in the rear. I notched my horse collar crossmember( 85 4runner). Stock CV in the front converted to a square shaft. All work awesome, no vibes(except for the square one obviously).

when you notched it did you replate it. Any pics?

Thanks for the help everyone

[SLIVER]

I did not replate it, I was informed that it was not a structual x member. I didn't take any pics of it. I just cut a rectangle out of the bottom of it and left part of the top of the x member there. So it is still intact and rigid, just with about a 2" tall and 5" wide rectangle cut out.

That crossmember IS structural.  Try getting rid of it altogether, your body mounts will shred your floor... 


I took mine completely out and replaced it with a 2x2x3/16" tube welded to the top of the frame a bit farther back.  I may have to get rid of that and go higher when I put the rear disco in there.. we'll see.

[4x4fiend [OP]]

cool. I'm gonna cut it out and make room for the cv, will either re-plate it or cut it out and put in a replacement. Should be fine to run with it notched for a week or so at least.

Thanks for all the help guys and gals 

[SLIVER]

Well if it is structrual, I have a thick a$$ t-case crossmember that is bolted on right in front of the horse shoe crossmember. I think that I'll be alright.
