I probably won't get a chance to install these until next week. I think the cross member will be a piece of cake compared to these. I see from reading older posts that some people have had issues with the dust boots on the front driveshaft after the diff drop. I don't think I've see anywhere that anyone has lower the transfer case mount an inch or so. Any reason why? That's a normal thing on Wranglers with lift kits. I would think that would help the driveshaft.
