I used Currie relocation brackets. This isn't to rotate the pinion as your question implies. The brackets are necessary in order to get the shock body away from the lower spring bucket due to the pinion angle changing.Do you need to relocate the rear axle shock mounts to rotate the pinion up like this?
'bout time :cheer:I finally got around to installing the engine skid after it sat in the garage floor for nearly two months.View attachment 71686
Honestly I'm not sure. I read where you basically just set the rear pinion in line or just a degree or so below the top double cardan ujoint and then the same with the front only a little higher and so far it drives fine with no vibes up to about 60mph. Also little update. I was able to mash the tub some and get a little clearance there and it's night and day for sound in the Jeep driving. Pretty sure it fixed the sound issue. Just did it Sunday.
If you wouldn't mind, could you put an angle finder on the bottom of your pinion. I am about to be in the same boat as you with a 3" spring lift, MML and BL, SYE and CV Driveshaft, and a 14 degree pinion angle. I would like to estimate what my pinion angle is going to be after my Savvy Tummy tuck so I can cut or adjust some brackets (mainly shocks and spring buckets). It's really hard to find any final pinion angle after a lift and savvy tummy tuck. The problem is I have a regular length SYE and not the super short and want to see if I will have to switch to a Super Short. Appreciate the future help.

Just set the pinion angle according to the angles on the ujoint
Drive, it with the front disconnected. Vibration? No, good job. Yes, keep adjusting.
Hmm never heard that yet. Currently it drives pretty well in my opinion with no noticable vibration. The front pinion did seem like it was about 2 degrees less than the front driveshaft though which I've read is not set right. Will most likely need to adjust front upper arms for that since the lowers are burried already.
Thought I had today. If I were to put a 2 inch or 4 inch larger diameter tire on (33 to 35 or 37) that should help raise the differential some and help level out driveline correct??
Rear driveline can be eye balled and dialed in by feel. Front needs adjustment till you get good return to center and no vibes. The only measurements I’d worry with is centering the axles.
