I'm having issues after my lift was install. I had 4 of the 5100's and 2" blocks installed A week ago. The front shock are set up for 1 3/4" of lift. My local Toyota dealer lifted it for me. I haven't driven it much until last weekend. I am thinking something might be out of line. While driving down the road I can hear/feel a whine. When you take your foot off of the gas it goes away. Even though they said the did the front end alignment the tires are definitely toeing in. I am going to bring it back in this week, just looking for some ideas. Or if anyone else has had this problem.
