I am wondering if I can put a specific sealant around the outer ends of my replacement CV boots to keep grease in and keep the elements out. I thought of a non-hardening oil-resistant sealant (Permatex has one). I think this might end up clogging the CV joint if drawn inside, and might not resist grease anyways. I am stumped. Searching the internet suggests nobody cares about this.
more detail: my CV axle boots leaked grease so much there was a nasty cakey coating on my control arms EDIT the boots were not ripped, the grease squeezed out between the joint and boot metal rim - they were torqued pretty tight. one of the axles actually had rust underneath the boot. There are no clamps on either end of the original boot. the original cv axle itself appears to have had an epoxy coating on it. aftermarket kits have pinch clamps for the rubber end, but the metal end around the joint - where all the grease comes out - still seems not to have anything there except the six bolts squeezing the metal boot rim and joint onto the spindle. …I can hear someone asking already : yes I could get a new axle assy but the problem still stands about sealant.
