I see thread is 2 years old, but thought I'd add that I also did the TF 2.5" coil lift with 35's. Steering was loose afterwards due to caster loss. I was down to only 2-3° after the lift (which actually gave me 3.5" front from lift and 1.5" from larger tires for total 5" of lift up front). I added TF fixed length LCA's and drive was much better though I didn't recheck my caster angle. Just wanted to add my 2¢
