Rear axel set up

I need to twist my rear axel so I can weld the axel brackets up. I have a AMC 20 rear end and the jeep is a CJ7 .. It has a 4.5 Rubicon lift. The trans is a NV4500 with a Dana 300 transfer case. Does anyone know how many degrees I need to twist the rear end. I hope I gave enough info. Thanks

You need to get an angle finder and determine that for yourself. Everybody has a different setup.

I believe I've given this link to you before, but here it is again. Read it, learn it, understand it.

Thanks CSP I have read this before. I still do get how many degrees I should turn the rear end . I am going to go with the CV type u joint and a Tom Wood drive shaft. I know people say turn it till it lines up with the yoke of the transfer case. Maybe I just have to get a straight edge and craw under there and try to figure out what looks good.

Look at the third diagram on that webpage. That's how it's supposed to look. Do some searching on this site and other CJ forums. You're not the first person to ask this question and people have posted multiple pictures, but you want any angle in the ujoints to be at the CV end of the shaft. Your rear can point two or three degrees down from being a straight line to make up for upward rotation of the pinion under power.
