How long will it actually last? Well acutally, it'll be replaced tomorrow (hopefully) with a nice piece of 1/2" thick steel.

How long would it have lasted if I kept it on there 24/7? Who knows. Can drop a couple more bucks for treated wood if you wanted to.

 

4crawler sells shimsshorter shackles will reduce your lift and also rotate your pinion down towards the ground, possibly increasing the u-joint angle. so maybe read here (search the page for the word 'cardan'): http://www.4crawler.com/4x4/4R_suspension-III.shtml

 

Well I know about cv shafts. It's just that they want $250-300 to make mine into a cv, and I was like hell, I'll figure something out! lol...

Wow, only $7 for the 4crawler shims. That's badass. Just wondering if it'll work with trailgear's springs...

 

I would think they would seeing how the the springs have to fit to the stock mounting pads, so wouldn't that also mean that the shims would too?

 

Actually just measured... 2.25" wide perches and leafs, so they're a 1/4" wider than stock.

So I just realized I can't measure my driveline angles. Don't even have the transfer case or 3rd member in lol...

And also, as far as phasing goes, both joints are supposed to be lined like O==|=======O right and not ||==|======O right? If that makes sense...

 

well, even though it's constant velocity, it's not a CV joint like the front is.

as for the shims, they mount on the pin between the spring and perch, so why wouldn't they work?

 

yeah, the ends of the shaft should be mirror images of each other so:
]==[O|O]===========[
or
O==O]|[O===========O

(the verticle line | is the center carrier bearing on a 2 piece shaft)

additionally, the angles at each end of each shaft section should be as close to the same as possible

 

Eh, mine's a single piece with the slip shaft.

Well that's what I though. Mine's been clocked at 90º, but I've had no problems until I took off the bed and potentially changed the tcase and pinion angle to cause bad vibrations. Maybe it'll clear up if I clock it right... Dunno, guess it's something else to look into...

 

Wow, I dunno if it's the fact that I phased the dshaft correctly, or that I added about two coke bottles full of gear oil to the tcase, or what, but the noise/vibration is nearly gone. It's still there, and from the fact that I took off the bed no doubt, but I imagine once I get longer shackles or add some heavy plate for the flatbed or get some shims, it'll all go away. It's actually drivable now.

And I measured my angle and came up with FT-RT 47.13/16", and FB-RB 48.7/16". So that makes 1.3/8" difference, or 19.8º (right?). So is that within normal operating range for a single cardian driveshaft?

 

well i skipped to the bottom because i didnt want to read it all but, alot of times its a ujoint that'll give vibs, even if it doesnt fell bad by doing a movement test doesnt mean its not, and if its not then you have spare trail parts for the glove box,

 

holy bump! I thought Clint was back!

 

The obvious solution to me would be to weight down the bed. Maybe a pole and some friends could help



similarity?

 

Hahaha WIN!
