Finally decided to address my badly leaking power steering system today by first tightening the clamps on the return lines, making a new gasket for the reservoir cap (whenever I run the truck frothy ATF spews from the cap) and finally flushing the system and replenishing it with new ATF. I took it for a test drive and the gear box as groaning as usual until eventually I almost lost all power steering. I checked the reservoir and it was empty. I thought maybe there was air in the system taking up space that I hadn't totally evacuated and I put some more ATF in. Power steering was back! but then when I stopped the truck and got out I noticed a healthy stream of ATF pouring from the gear box. Guess its time to bust out the wallet. From my searching on here people tend to suggest buying a remanufactured gear box rather than trying to rebuild it yourself as they often leak when you rebuild them yourself. I've also seen people suggest getting an 80 series gear box to replace the fj60 gearbox. I'm trying to figure out what I should do, would love some advice! I like saving money and Im not afraid of taking something apart to rebuild it but where should I source a kit for this if I go that route? If its best to just buy a whole rebuilt box would I be better off getting an 80 series box or would it not even fit on an '85? Thanks!
