I've done a fair amount of searching and reading through posts on this topic, but am looking for further clarification as my situation is a little different due to my location. My passenger side inboard boot is leaking a reasonable amount of grease at the small clamp (about 1/8" to 3/16" layer of leaked grease on axle shaft). These appear to be OEM axles and I am at 270,000 miles, so its hard to say if they are original or not. I have inspected the boot thoroughly and it is not torn or cracked whatsoever, but I do recognize that if grease is leaking at the clamp, the boot is likely not far off. When I am turning left at full lock, there is a slight groan (NOT a popping sound) that can be heard from the passenger CV axle, likely from lack of lubrication at the inboard CV joint. Ideally, I would be replacing both driver and passenger side CV axles with new OEM, but at $900 Canadian per side (yes, you read that correctly), I'll be putting that off until the borders are open and I can make the trek down to the land of the free. I'd like to just re-grease with a needle attachment and re-clamp with the McMaster-Carr style smooth band clamp and see where that gets me, and I would be buying the inner boot kit, PN 0443760080, just for the correct grease, but the best price I have been able to find for that in Canuck Bucks is $122 with shipping, which is one expensive tube of grease. I understand that using the OEM grease is the way to go, but has anyone had any long term luck with another product? Sidebar question: without actually sliding the boot down and seeing how much grease I lost, is there a way to know how much to add?
