Anybody know what size the inner tie rods are on an 93 fwd loyale? I need to rent the tool from the local auto store but don't know the size adapter I need. Been trying to find out bit can't seem to locate the info. Thanks.

I just used  2 adjustable wrenches .  I think the flats on the inner rod  is  19 mm   , 

i've never used a tie rod tool or special socket on the many Subaru tie rods i've done, they're rather easy IMO.

i've used plumbers wrenches in the past as well.  the smaller flat spot for holding the tie rod stationary is 13mm.

Yeah, I was confused by th question. there is a flat spot on the rod, and the nut and faces on the end. What special tool? I just use regular metric wrenches.
