I have a leaking pinion seal on my 1996 FZJ80 9.5" elocker rear axle. Tired of leaks, my first stop was Marlin to try and buy an EcoSeal Pinion Seal. In the past I have used the Marlin EcoSeal on the front axle, and been very happy with how they work.
Yesterday I called Marlin, and was told they only had an EcoSeal Pinion Seal for the 8" differential, not the 9.5".
Today when I went to order a factory Toyota seal, part number 90311-38047, I found it is the same seal for both the 8" axle and the 9.5" axle.
Does anyone have an idea why the EcoSeal does not fit the Land Cruiser 9.5" axle, but fits the 4Runner 8" axle?
