Can I replace tie rods on the ground without a jack

 

The ones in front of the axle,from the steering box to pass. side spindle, yes.

I'm pretty sure the track rod behind the axle requires pulling the wheel to get the rod end's out of the spindle.

 

Sweet these tierods are beeefy from terrafirma

 

did you buy the terrafirma rods ? Keep us posted this is my next project on the list , assuming something else doesn't go kaput before I get the money and get the parts here !
I am concerned about the adjustable tie rod link....mine looks too rusty to come apart...I was just going to get a new one as I assume by the pics of the terrafirma kit that that part is NOT included in their kit ?

 

The TF rods w/ endlinks are HUUUUUUUUUUUUGE....its about 1.25inch of solid steel and the tie rod ends seem high quality with good boots on them. Install was a cake but you will need alignment afterwards (i needed one anyways it has never been aligned) According to my alignment guy, these bars are very simple to get in spec and super easy to work on.

Nonetheless my steering is nice and firm plus I dont have to worry about bending one like the stock hollow crap. A++++++++++++++++++++++

 

Nice. The firestone shop where I live sells a "lifetime" alignment. It's pricey, $150 I think, but you get free alignments as long as you own the car. If you off-road much, it might be worth it.
