I have a new Tom woods shaft waiting to be installed. and all this talk of transfer case failure is got me second guessing if I should install it or just keep replacing it with a new stock one. I do have adjustable front lowers. How do u decide what caster and pinion to run. I know you have to sacrifice caster to gain the right pinion but how do you know whats good?? Also any one know if there are problems with after market rear shafts?? I have a woods rear waiting to be put on. But I have the stock control arms. Do you think there would e problems with installing it?? I do have the JKU. Thanks for the info

 

to install the rear shaft, you NEED to set your pinion in line with your driveshaft. you will need adjustable rear upper control arms to do this. up front, you CANNOT set your pinion to be inline with your drive shaft as that would give you next to no caster if not negative caster. you just need to set it close to factory which is about +4.2°.

 

I do have a 3.5 lift. I've read that people set there caster to around 5. Does that sound right. It's just reading all these post about transfer case failures has got me scared.

 

more positive caster like +5° will help your jeep to feel better at highway speeds. if your drive shaft is balanced well and you are running stock gears or 4.88's, you should be just fine doing this. if you are running 5.13 or higher, you may find that this is a bit too much and you'll know if if you have drive line vibrations. if you do, you will need to set your caster closer to stock which is +4.2°
