For those running the 4.88's, do you have a concern about the pinion gear being weak? I've read some comments from some FJ guys and 5th gens that teeth "go missing".

I am getting ready to order gears and have 285/75's. I'd go 4.56 to be safe... but coming from slow dual sport motorcycles (WR250R), it seems the 4Runner does just fine at higher RPM's as well? (~200rpm difference according to grimjeeper website)

I usually take 1-2 road trips per year and the rest of the time is city, limited highway, some off-roading, and occasional light towing.

If the pinion "issues" are not much of a concern, then the 4.88's really do sound more appealing. I'd love to hear some feedback!
