The last "fix" I don't have any shots of.
Like many IFS drivers, once the truck was lifted, the front CV boots tore. I, like other third gen 4runner/first gen taco owners, replaced the axles and had a bad, leaking passenger side diff seal.
I replaced with OEM remans, and put in probably 5 different seals, all to no avail. After reading online, I tried the Two Seal approach, essentially putting in two of the passenger side diff seals in, as there is plenty of room for them. This worked, and I no longer leak gear oil from the passenger side tube.
I know others have been able to get brand new axles, instead of remans, but, 1. they are pricey, and 2., it seems to be very difficult to get a hold of a new axle any more. Most dealers will tell you they don't exist. This fix seems to work well, and saves the hassle and expense of having to track down a new axle.
