I am replacing the inner boot because I'll already have the whole axle out and I will know that both boots are brand new. I just don't want to have to pull the axle out again if the inner boot does somehow tear. Besides- the inner boot kit was only $10 and I'd say that's a good price.

I'll keep that in mind for next time- however I haven't had any vibration issues whatsoever before my outer boot tore. I'm just going to repack the joints and wait until I get vibrations again-then I will probably get them rebuilt or buy OE new ones. Actually come to think of it- I have brand new ball bearings from the last outer joint that I replaced on my passenger side axle. I ordered a new outer joint from the stealership and the threads were all screwed up where the axle nut screws on. I kept the new ball bearings and carrier and put the old ones into the defective joint, and swapped the defective joint for a new one at the stealership. Looks like I'll put those spare bearings into my driver's side outer joint. Awesome! Glad I just remembered that!
