Is it really necessary to have them if you're planning on doing a lift? Who makes the best m/h? Is there one available for the 2003/4?

 

To the best of my knowledge there is no 4th gen manual hub anything.

There "might" be hope once the new 2005 Tacoma hits which is supposed to share alot of the same parts with the 4th Gen 4Runner.

Keep in mind that 3rd Gen stuff more than likely will not work, your front end is in theory the same but in reality very different.

You even have the steering rack in FRONT of the tries where as the 3rd Gens/Older Tacoma's (that sounds funny) have it behind the tires.

I would like to know why they moved it? More than likely due to the vibration issues.
