Hi there.Well my power steering in my 1980 fj40 starting leaking 3 days ago.It's leaking right where the steering shaft goes into the box.The top seal. How big of a PITA is it going to be to change?I'll pull the whole box out of the truck.Do I really hafta buy the whole seal kit just to fix the one seal?Anybody have a part number for me?I gotta get this thing fixed fast.It's my DD and it trashing my truck. HELP!!!! Never tore into a power steering box and any advice would be great.I did search, but didn't find to much info..... TIA Ryan 78&80 fj40's
