I did mine today. It would have been a pretty easy job if my balljoint bolts didn't shear off
The OEM boots looked OK with 216k miles on them, but as I removed them it was pretty clear that they were not long for this world as the rubber was relatively easy to tear and not that supple.
I ditched the included OEM grease and tried
Green Grease.
Hokey marketing, but the reviews are good.
The factory grease inside the inner boot looked pretty good, but the oil was separating from the thickener. The green grease stuff won't separate and is much much stickier than the black stuff- since the CV bearings don't really spin (like a wheel bearing) I figured the sticker stuff would hold on the loaded surfaces better.
The cost of the boots was more than a lifetime autozone CV (I've never had problems with them before), but I figured the non-damaged OEM units will last forever as long as the boots are doing their job.
