So, heres my nightmare.....
Had 5.13 gears installed about a month/2 months back and while having em installed, I had a tatton double carden installed, because my stocker started to throw grease so I figured it would be a good time to upgrade.
Picked up my jeep from having the gears done, noticed the vibs I(which I already knew about cause the dude who did the gears noticed during the test drive); figured no biggie, just have to bring my pinion up a bit to bring it in line. That was a no go, brought my pinion up to 6 degrees
and still got vibes. Figured, well, this shaft must be off balance, maybe it got damaged during the shipping process, ok, so, I sent er back, and got a new one sent out. Just received the new one in last Thursday, installed it, and guess what.....IT VIBRATES!. Just as bad as before, and at the same speed, 45 MPH plus.....(and would like to add just for clarification, the vibs go away when the shaft is removed).
I had my caster checked beforehand, just to assure myself that it wasnt to high for a double carden, and my caster was at 3 degrees. On the low side of factory setting. Mind you, I am only at 2.5 inches of lift.
So, at this point, I am thinking that, either Tatton shafts suck the big one, I am extremely unlucky and got 2 unbalanced shafts (both highly unlikely, first off, the shaft is extremely high quality I will point out, and, there is no way I got 2 unbalanced shafts)....
So, this basically leaves me at WTF?!?! I can go with another company, Woods, JE Reel. etc... but I have the feeling that I will still have the same results. The only theory I have is that due to the 5.13s gears, the shaft is spinning to fast to not vibrate, but then again, almost everyone who has done gears, ie 5.13, 538, etc. has a CV front shaft and no issues.
