Depending on how high you lifted after putting the new bilsteins on, you CV axles could be binding. That would make sense. Also Sway bar links could be worn out and now with the additional lift making it more noticeable because of new angles created from the lift. With it being more noticable...
I would contact Keith with Dirty Deeds. I went through a complete new exhaust system and different mufflers just to be disappointed. I basically lost low end torque and I should mention this is on my 06 Tundra. My girlfriend has a V8 T4R and she went with dirty deeds 16" and it sounds awesome...
I have the C59-701Vs and I love them. I have about 350-400 pounds of static weight added. I don't think you can go wrong with Dobinsons. I'd consider the C59-327 for your additional static weight plus added towing support.

As I already mentioned for me the chalk method has always been the most accurate way to ensure proper tire contact. I feel confident in using the calculator from now on instead of the chalk. They also have a wheel offset calculator that is pretty cool and gives a nice visual.
Long time lurker first time poster. I came across this thread while looking for cheap mods for the 4th gen. I decided I would chime in and give my .02 cents. I use the chalk method when I change model or size of tire. This has been the best way for me to make sure the tires are properly...
