Got my axle back, got my 4in lift on, my sye installed and my new tires on. Now I have a few questions. Where are you guys measuring from to make sure your axles are centered left and right? I put adjustable upper control arms on my rear and fixed on the bottom rear, where should I measure to make sure the top are squared from front to back. Also I'm getting ready to order a driveshaft, but I want to make sure I get the right length, where should I measure that from. I eyeballed my pinion angle, any idea if it's close, at least close enough to get a accurate measure for my driveshaft length?

you don't have the ability to adjust squareness fore-aft since your lowers are fixed, but I measured from the front of the axle tube just outside the LCA bracket to the middle transfer case skidplate bolt.

For side to side to set the track bar length, I measured from the frame to a mold line in the tread voids of my KO2's, just like I use for toe adjustments.

Awesome thank you, I didn't think I needed to square fore-aft since I had fixed lowers but wanted to make sure!

no problem. All you need to think about is your pinion angle, and cycling your suspension afterward to make sure your diff cover and track bar aren't hitting the fuel tank skid.

Yea I'm reasrching now where to properly measure for a driveshaft, i think I need 21in. I need to get a angle finder and try and get the pinion angle a little closer before I order the shift so I get the right size
