BOOM! Long awaited driveshaft adapters...

[rascole]

As far as the sound, the video may not represent exactly how I hear it. I would describe it more as a clicking sound. When I replaced the shaft I checked for movement and found none, all 4 wheels were off the ground because I was doing rear brakes at the same time. As far as the sound, it is barely audible inside the cabin when I am close to another car or building and hear the echo. I drove it in to work this morning and hit 75 mph for 5+ miles and felt no vibration whatsoever. This weekend I will take the front shaft off and run it again with the camera. Remember that this sound was NOT there before I swapped shafts so I doubt the pinion bearing would fail at the same time, BUT.

The high-speed CV on the stock shaft is fantastic at cancelling vibes and masking any drivetrain noises that would otherwise be transmitted to the rest of the vehicle. Its entirely possible that the source of the noise has been there all along...but hidden by the stock shaft.

Here is a video with the camera pointed right at the double cardan.

Great video....but I don't see any issues that would cause the noise.

 

[rascole]

Same here. I'm going to pull the front shaft and try it out. I'm more curious than anything else.

 

[rascole]

So, pulled the shaft when I got home from work and bad/good news is it is not the shaft. Sounds is still there and it sounds like it may be the transfer case. Oh crap! Going to test more tomorrow.

Thats the same sound I had when my transfer case blew. May be time to get it checked out.

 

[rascole]

That's what I'm afraid of.

on a Tcase note I noticed a lot of t case issues are due to nasty fluid. they say change the fluid every 50k but its nasty at 50k so I changed it to 25k and its still pretty dirty. I plan on changing it after 15k to see. I know its weird but many issues I have seen people post up on t cases they mention they have never changed the fluid or when they check the fluid its nasty looking.

 

[rascole]

Mine was serviced less than 10k when I had the plastic shift fork replaced with the metal one.

The clicking may be the chain hitting the inside surface of the case. They stretch as they wear....sometimes wearing completely through the case. Later years got an internal snubber plate to help control the "slap" but those can come loose and cause even more damage than a loose chain. Regardless...a chain swap is not too tough of a job. Also check the front output shaft bearing for slop.
I'm with 06H3....fluid changes are critical. I honestly don't know what makes the fluid so nasty in such a short time. There are no clutches or viscous coupling in there....so the dark fluid must be a combination of heat and metal particulate.
FWIW...my 99 Burb has 210k miles on one t-case fluid change, (NP-246)....but it is part-time. The hummer is spinning everything...all the time, so that must also contribute to the short fluid life.

 

[rascole]

I did read that the 06's had a lower fill plug, am I correct? There is NO slop on the output shaft and the front diff is tight as well. Gonna put it on the backyard dyno with the front shaft removed tonight to confirm it.

 

[H3slate]

The 06's do have a lower fill plug. You have to add additional fluid through the speed sensor plug to get the right amount.

Well receive my driveshaft today and mounted the adapter idk if I should paint it since it is already rusting.

Was this one from the ebay site posted at the begging of this thread, if not where/how did you order it? Thank you

 

[RamRod]

Yup this is the one from the eBay seller previously posted

Yeah pretty much, here's the link...there's many other seller that advertise the same product about cheaper as well however I decided to go with what everyone here has used before instead of testing new waters

Is there a difference between these two?

Nothing. I had noticed this when I was looking for mine.

One bolts in with a flange. One bolts in with u-joint straps.
You need the one with the flange, (the hack & tap shaft).

 

[4speedfunk]

Also...I'm getting a standard "test shaft" made. Atv (along with several other driveline guys) have suggested this. So I'm going to foot the bill for one and do some test installs to see how it compares to the 1310 cv shafts that everyone on here is running.

I'll post up my findings.

 

[08H3]

Had some time this morning to put the shaft in that has been setting on the shelf for a while. I know some have suspected balance issues, but this one seems great. No issues from city driving through interstate speeds.

4Speed- What's the standard "test shaft" you mentioned? Just a singe U-Joint on each end or something else?

Yup. Single u-joint on each end, with a slip collar at the front axle. Not sure if it will work with my solid axle but, it might be okay with the IFS guys.

So, is rascole having T-case issues, or Tatton drive shaft issues? I Have received my Tatton shaft, but haven't had time to install it yet.
As soon as I get time, I will install it, and report it's performance.

Rascole's shaft is just fine (that's what she said). My TC is in the shop being rebuilt, low fluid level and chain stretch are the culprit. When I had the metal for installed 3 years ago the mechanic was unaware of the too low fill point. Now I am going to fill it after it is installed with 1.7 qts just to be sure.

 

[RamRod]

Got my shaft today, installing it along with the adaptor was a breeze! Only drove it around the block but everything felt fine for what that's worth... I will take it on the highway this week and see how that feels
