Thanks for the reminder about tire size, I knew I'd forget to include something important. I'm planning on staying with the 37's and preferably 17" wheels to keep a lot of sidewall. And I'm happy with the lift height.
And I know about the Spyntec hub option for 44's, but there are some concerns there. Biggest thing is I have read a few reviews from those who used them where the quality of the seals was an issue and water contamination in the bearings was ongoing. Lots of water here in Florida. And I believe that kit widens the front track as well, about 1-1/2" IIRC, but that's just from memory. And PR44 + Spyntec = PR60 in terms of cost.
Are there other hub kits out there besides Spyntec?
Main reason for the desire for unlocking hubs is the front shaft angle from the TC is pretty extreme on a lifted 3.6, due to the inclination of the engine and trans. I do a lot of highway miles and I suspect even a double cardan is going to be a high maintenance item with these angles.
