Hey guys. I am joining because I like to do my own work on my own 01 YukonXL 4x4. It is not my daily driver right now. I will be looking to install a suspension lift and some 35-37's. I have installed a 3" body lift when I replaced the brake lines last year. I will do some reading up front because I know how aggravating it is for the new guy to start asking the same questions that have been asked 100 times already. So future plans include. 1. 6" Suspension Lift 2. Transfer case rebuild - mine is starting to leak 3. Front and rear gear change and rebuild for the front dif.
