I also have to think that even without the subject of vibrations, there would be less torque with an angle than a straight line in general, and more stress on that angle point even with a double U joint there. At least the front DS is hella longer than the rear. I feel good about dropping the...

Roger that. I mean I still intend to pull the shaft and inspect the joints, but I am confident that dropping the belly back down will help to decrease that TC/DC angle. I'd do a higher MM, but again the existing one already gave me a headache pinching those wires between tub and trans and $$$$...

In fact in my illustration I have the pinion at 0 degrees, and if one were to rotate that to 1-2 degrees down, it would make that TC/DC angle even more pronounced.

I get that, but height of lift might not mean their TC to DC angle is as extreme. I mathed this, which kind of illustrates what I think happened. Assuming pinion angle is 0 degrees in both, the TC to DC angle becomes more pronounced with a belly tuck (without further lifting the motor to retain...

Here's how my brain is visualizing this, does this track?: Belly up brings trans up, tilting engine/trans down to front on MM pivot point, creating more angle at the TC end of the DC shaft. Either the DC does not appreciate that angle, or Ujoint(s) suddenly buggered, or both. No adjustment of...

I have the BL (with the emus) for the 33s I am on, and BL really doesnt mess with drivetrain, yes? Trackbar tweaking is already on the list, as the rear still has whatever nonadjustable the last owner had put on with a straight adapter. I have a tereflex adjustable and angled bracket to put on...

Hard to tell total because I did not go from stock. When i bought it it had somewhat of a lift in it (maybe around 2'?), and a TC drop spacer set installed. I did not measure the height increase of the trans from shovel to teraflex belly-up skid.

But again: Rubicon. No SY to E

But Shawn is talking about 4"+ of driveline lift. If still light out enough to get under after work, I am going to peek into the hole in the new skid to see if anything is remotely close to it besides the obvious trans mount. The more I think about it the more I am blaming the new vibes on the...

Rubicon with DC, and 4 speed bestest trans

Really the main change that seems to have set this off is the belly up skid. I have some 1" skid spacers (defeating the belly up point, but it was already bought and installed so... at least not a shovel any more) coming to try out instead of adding more height to the motor. Lifting the motor is...

2 years since installing the Tom Woods shaft.

Bonus question: while I still have an ounce of motivation to fiddle underneath, I plan to replace the rear sway links (noisy rattle AF), with only the OME spring lift will I need to go longer than stock length?

It's currently at 0 degrees. Double/triple checked with digital gauges. Went off the flat back of the gear housing and the DC shaft straight section. I started testing at 3 degrees, and dialed up to 0 in half degree increments.
