from the voice of recent personal experience, having just installed new inners, outers and swaybar bushings yesterday. i bought both inners and both outers from O'Riellys for roughly 70 dollas. removing the outer is already described, but i removed the inner first, removing them both as an assembly. inners from the factory require a 1 5/16" wrench (an inner tie rod removal tool is available for renting). i didnt bother to get one though, i just used a chain wrench, after i moved the wheel to get some room. aftermarket inners are 1 1/4 or maybe 1 9/32"...not sure cause i used a cresent wrench. aftermarket outers are a different length than factory, so you cant count threads and be cool with it.
also, to aid in inner removal, pop the head off the rivet (after you remove the boot). if you can, pull the pin from the rivet too. makes it easier to trash up the rest of the rivet as you back the inner off. the left side is easier to get to than the right side. thats where the inner tie rod remval tool would come in handy. what i did on the right side was turn the wheel all the way to the left (pushing the right hand shaft all the way out). it put the inner nut just on the outside of the motor mount, but still over the subframe. space is tight, watch your hands and knuckles. sheet metal seams dont feel good on flesh. im looking at a cut on my knuckle from yesterday, caused by losing grip on the wrench and hitting the body seam......i need stitches...
all in all, including the 2 hours i spent doing an alignment, and 1 hour for the sway bar bushings...total time from front end being jacked up to front end being put back on the ground, 7 hours.
