Can you replace inner tierod without removing outter?
 

Title says it.
reason is, i dont have the puller for the outter, it looks to me i can just thread the old one out, and new outter tierod in, anybody done this??

Yeah you can do it like that but just take the nut off and a good blow with a hammer to boss (this the arm coming off the spindle) and it will pop right out. That way you can measure and get the length the same.
