Please help with ideas to take off shutter??

No that sounds like a great idea, I just need to find somewhere local that has this kind of expertise thanks

 

Ok i just measured the driveshalf length, an I got 74 3/4 inches at the bottom and 75 1/4 at the top... Thats 1/2 difference I have the 4 degree shims in right now, maybe i'll grab my 2 1/2 degree shims spin them around like you did with the thinner side facing the rear. Might help...?

 

ok i took out the 4 degree shims that i had thin side facing forward, and replaced them with the 2 1/2 degree shims thin side facing the rear and the drive line vib got way worst!! Even though my trans flange and axle flange look close to being parallel like bjmoose said they should be

 

I had the shudder....it pretty much took most of mine away

 

what did??

 

Lol sorry....the all pro leafs did

 

Wow, that was quick. What was the measurement after the swap?

 

Yep, I just did some "back-o-the-envelope" calculations and it looks like a roughly 6 to 8 degree change would have made the flanges parallel. So I'm curious as to what the results are.

We don't know what the total driveline angle is, and we don't know what any displacement from side to side is. The bigger the total angle, the more likely to have vibration.

If you measure again and those flanges are roughly parallel (say 75" each) then at that point I'd definitely punt and consult a driveline shop.

 

I measured after i installed the 2 1/2 degree shims "backwards" an it seems farther off than before... Is that possible? Its kinda hard to get an exact measurement on top of the drive shaft by myself. Either way i put the 4 degree shims back in with the thin thinner side forward, so the axle is kicked up more. An going to have to settle for that untill i can find a drive line shop to look into the problem.

 

Say what? How can any drive shaft not have a slip yoke?

 

I think i need to go with an even bigger shim like a 5 degree, cause that would get the axle kicked up and help make the bottom measurement of the drive line closer to the top. Because my bottom drive line measurement was shorter by almost a 1/2 inch, than the top drive line measurement. Does this sound correct??

 

that does seem odd. It's hard to go forward if you can't have confidence in the exactness of your measurements.

A driveline shop, if you can find one, will straighten you out. (pardon the pun.)

 

Draw diagrams on a sheet of paper.

If the wedge is "fat back" it forces the pinion up, moving the bottom of the flange closer to the front. So, no, I would not agree with your statement.

 

Your right, man now I wish i would of measured twice

 

thanks for your knowledge an time, I'm going to figure the problem out one way or another

 

Dog headed persistence is half the key.

When I'm dealing with "tweaky" stuff like this, I always measure at least twice.

Do you play guitar? Tuning out a vibration is a lot like getting all the guitar strings in tune. A key measurement has to be right, then all the others have to be right relative to it.

 

And I'll help as I can, but I'm no expert. Using the same analogy, I've only tuned one guitar.

 

haha I have persistence, but not at learning to play the guitar i try'd back in high school but never caught on. I think i'm gonna try to buy a cheap degree finder and play with that and see what i come up with?

 

Yeah. Try it out. And reread that 4crawler driveline link.

Also, there's some good info iirc on Tom woods driveline site.

 

I found a local balancing shop that builds drivelines only 15mins from me, so I'm gonna try and head down there Friday or Monday and see what they have to say about it. Hopefully they know there stuff
