yeah I have have it. There are some other posts about this....they call it axle-wrap or something like that. After reading some other posts, it appears that almost all tacomas do this, and all dealers tell us the same thing....."they all do it" . Some of the guys talk about greasing the propeller shaft and the u joints. Find a post that's titled "2003 Tacoma Double cab-transmission" and it has some good info on this.
