Did you get a 4-wheel alignment or just a front-end alignment? Have them check caster, toe, and camber. Something isn't lined up.

You could have blown 1 shock, but you should be able to see that on your tires (multiple flat spots around its face).

Also, there's a steering knuckle that works like a tie rod. If there's slop (if you can wiggle it at all) in that joint with both front tires off the ground, then it's bad. The same goes for ball joints. If you can move the wheels on the spindle or the suspension at all, closely inspect your ball joints and tie rods. These things wear as cars get older. If there's slop in any joint, replace that part.

Tell the next shop about the trouble you've been having, and ask them to check out the whole steering rack and suspension . Then, when you drop it off, ask if they'll test drive it when they're done to make sure it's straight, and if you can come back in a week to have it tweaked if it's off. You'll have all the guarantee you need that it will work right when they're done. Most shops will stand behind their work.

As for the axles... Buy axles with a lifetime warranty. Hondas don't have the beefiest axles. You could upgrade to a higher quality axle like www.raxles.com sells, or just stop cutting your CV boots on crap. My axle boots are both cut right now, and they're less than 7000 miles old. One picked up a plastic bag, it tightened as it stretched and sawed through the boot... Accident or not, once the boot goes, any axle will quickly start to die. When mine go, I get them warranty replaced, and I replace them myself. It takes (me) about 30 minutes to replace an axle and re-pack the front wheel bearing on a Honda. Axles are between $60 and $120 depending on the quality. They're all remanufactured. Don't fool yourself.
