I have been reading on-line about a rear differential vent modification that a bunch of the owners are doing. They are removing the original rear axle breather then replacing it with number 38323-C601A which is nothing more than a barbed hose fitting, then running 6 ft. of fuel line from it and routing it up into the rear tail light housing and terminating it with just a simple in-line fuel filter to protect opening from dust and dirt. My factory rear axle breather failed but I was fortunate that it only blew out my rear diff cover seal. Says this mod provides better axle venting by not only letting air pressure escape but also allowing air back in. They also say that is sort the manner in which the front differential is vented. I would like to perform this mod but my only concern is possible condensation build-up resulting in water getting back into the real axle and differential over time...especially in Massachusetts Hot/cold climate. Should this be a concern? Thanks.
