I always figured that the 2f and 3fe in my 60 and 62 were good for about 300k before rebuild. I never got that far on either because I got the bug for the next ride. Now that I have found the truck that does it all for me...96 FZJ.....power, lux, style, durability (oh, did I mention the locking front and rear diffs) I am wondering how long it will go before major overhaul.....assuming I change fluids and take care of it? Any ideas? What is the most milage you have heard of on FZJ??????
