way past midway. im about 2 hours to 90 minutes from downtown on a good day. i'm FAR FAR south side.


well you could call the dealer or ask on toyotanation.com
a synthetic gear lube, im not sure if it will last longer but it will have a more consistent viscosity than regular. meaning that in the cold cold it will be closer to the thickness it should be than the regular lube which will be much thicker. may reduce some unwanted noise on really cold days. im not sure what goes bad with gear lube over time, if its the additives which break down or if it just becomes contaminated. if theres a breather tube on the differential case (some have, some dont) you can put a small breather filter onto the end of it and ziptie it up and out of the way. as the differential gets hot and cold the fluid expands and contracts, air is pushed out and sucked in. a small filter on the end of the tube can guarantee that dust and road salt do not get into the lube.
