Mine is at 25 and I haven't had ne serious issues because of it, 29 does sound sorta steep tho but thats not very far from mine. If ur worried n want to drop it a few degrees, slip a few spacers between the skid plate bolts and drop the transfercase a little, then reweld perches. U could also put in lifted motor mounts, that will help lower ur angle as well.

Just a few more degrees like mine I would imagine, I have 1 inch TC drop n 1 inch browndog lifted motor mounts. I run a dana 44, duno if my axle being diff makes much of a diff. I think my yoke sits an inch farther forward than a dana 35 but I duno how it compares to an 8.8.

Overfill the 8.8 if you are worried about it.
You could put more lube in through the vent line or park the Jeep on a incline and put more in.
The worst that could happen would be you would blow gear lube out of your vent line.

Attached to the vent. Allows you to overfill. Fluid dumps into the can when it gets hot and expands.

Makes pinion bearings happy.

I don't think I would worry about lubrication; the oil sloshes around in there pretty good when it's all turning. Or, drive down steep hills a lot.

I don't recall what mine is....so I think I'll grab a fresh adult beverage, head out to the garage & do a pinion angle check of mine.
