I added the 1.5" Toytec AAL (Non TSB) with the 3* shims and Bilstein 5100's all around (1.75 up front). Turns out that the shims actually introduced drive line vibration, so I removed them tonight. I still have a very slight "hum" at about 20 mph, but it is 90% better. I may shim the carrier bearing this weekend. I am thinking that it is probably more likely to need the axle shims on a short bed Double Cab than the long bed for this mild of a lift. Just thought someone might benefit from my experience.
Here are my shims in case you are interested or have a larger lift.
