I have a 1995 LX w/a D15B7, the drivers side axle has both inner and outer CV boots torn but it is not clicking yet; passenger side has no rips. I know it is more economical to just replace the axle as a whole, my question is since the car has 154k miles on it should I replace both sides anyways?
Same question about wheel bearings, they aren't squealing at all, just have lots of miles on them. Can I add grease to them, or since they are OK don't worry?

I'm about to replace the bushings/upper control arms/balljoints/end links in the front end and since I'm tearing it all apart I figured it might be worth it.

 

If you're considering doing it, and are already going to have it all apart, do it all. No need to do the bare minimum then have something go out in the next x,000 miles. Also, make sure you get an alignment done afterward.
