Honda sells complete re-man axles, but only for 86-89 and 90-93 Accords I think.

If the boot has been ripped for a while and all the grease is slung out, chances are your joint is bad... even if it's not clicking. My experience with cleaning them out thoroughly in a parts washer and re-packing only saves about 50% of them. It's also pretty messy until you get the hang of it. At this point (20 years doing this stuff) I don't bother any more... I just go ahead and replace the joint if the boot blows.

Get a Honda outer joint kit which will come with everything you need as far as parts. They retail for $100 - $125. Pull the whole axle and work with it off the car. Don't let the inner joint come apart unless you plan to do all 4 boots, bands and grease while you're in there (recommended )

I use a cutoff wheel to cut through the old bands and peel them off. Then use a razor blade to cut the torn boot off. Wipe the excess grease off the outer joint. Hold the axle in one hand with the bad inner joint hanging downward, then take a BFH and beat the old joint off. The new joint comes pre-packed with grease... remember to put the boot on before the joint. READ THE INSTRUCTIONS because the joint has to be positioned on the axle in a particular spot. If you push it on too far you're hosed !!!!

If you're doing just the boot, you need to take it off the inner end of the axle. Remove the inner joint, inner boot, "tripod" inner joint thingy (requires snap ring pliers) harmonic damper and outer boot. When you go to put the new boots on, try spraying them with a bit of WD40... they'll go on like magic.

It's a messy job and there are probably 100 "preferred" ways to do it. Get a Helm manual, some old clothes and go at it. If you keep things clean you'll find it easier.
