I drive fast on the highway - usually around 70-75.

I want to lift 2.5" with Donahoe spacers - I am worried about this:
WARNING –– TACOMA LIFTING LIMITATIONS
If you let Toyota sell you a Tacoma with Automatic Differential Disconnect (ADD) - shame on you! These vehicles are limited to approximately 2” of suspension lift. These vehicles do not have manual unlocking hubs, consequently the front axles and CV joints spin 100% of the time the vehicle is in motion. Beyond 2” of lift would put the CV joints on sufficient angle to buzz you out of the cab at highway speeds (not a problem in off road terrain where the speeds are slower and/or the CV joints are constantly changing angle).



Does anyone have a 2.5" lift with ADD and have problems \with CV buzz/whine?

No, I've got 2.5 and no noise, I have to drive 70-80 in DFW to avoid be pushed into a guard rail. There's one or two on here with upto 3.5 that seem to run fine. As a rule you usually wont see trouble at or below 3"s. Theres always an exception to every rule, but I think most answers you get here will agree at 3"s.

Remember in the sue happy society we live in companys have to protect themselves with disclaimers for everything.

the problem varries from rig to rig. some run 3" will no problems but others run only 2" and blow boots right and left. One of the most common problems is vibration at speed. Most just get used to it...some never even notice it.

I know, not much help that that's the way it goes ;)

I'm running a full 3.5, I have a man. hub conversion and diff drop but still, locked in if I run it up to 60-70 it doesn't make any noise, just noticable drag.

I too have about 3.5" of lift with OME and a spacer combo. I replaced my boots in the very beginning, and never have since. I installed a custom 1 1/2 " DD drop and things are going fine :)

1.5" DD? good luck :rolleyes: you may soon be the second one to snap his rear diff mount bolt.
