Default 14 ff pinion angle

What is the max pinion angle you guys would run . Im moking mine up and I kept the T/c as high as poss. and have my pinion pointed up to the tc. It sits at 28* I think that is too high, but by how much. I need to lower the tc as well( the output flange is at 90* to the ground.. I tryed hard to keep the tc as high as possible through the whole build.Crap!!.

I would worry less about the axle and more about the angle your driveshaft needs to run at.

If you have a cv style driveshaft the pinion needs to point at the t-case.

On a 14 bolt, I myself have found out that the pinion bearings dont get enough lube when the pinion is pointed up more than 25-27 degrees. Had two good rear ends burn up on tow vehicle of mine when doing so. The total weight was over 14,000 pounds also, truck/trailer/cargo. To make it last I ended up making a diff cover that held more oil and over filled it also. There a awesome rear end aslong as you keep oil to all 3 pinion bearings. Hope this helps ya

How much lift do you have? Can you raise the motor at all to help slope the t case downhill at all so it isn't sitting level? How long is your rear driveshaft? Do you have a lot of droop with your suspension? Just curious what kind of driveshaft angle you are going to end up with when the suspension drops out.
I hate being bipolar, its great!
