Can anybody help? I own a 1990 Toyota 4Runner 4x4 SR5. I have just cracked a ring gear in my rear differential. I have checked numerous amounts of part sources around town. (Ottawa, Canada) but can’t seem to find any rear differentials without buying the whole rear end or brand new. I was told $600 - $1200 Canadian. I am obviously looking for a used or cheaper unit. I had received the specs from a color code and VN manual. It seems to be an 8” 4:56 ratio. If any one can help it would be greatly appreciated. This Canuck just needs some proper contacts!
