This also used to go along with changing out the muffler bearings.
But since all manufacturers wen to sealed muffler bearings, they no longer need to be replaced.
When the manufacturers all go to synthetic blinker fluid instead of the dino stuff, we'll never have to change it out either.
However, if you happen to own a Yugo, than both need to be changed on a regular basis.
