I have changed the cv boot on the drive shaft some weeks ago I have been driving a bit since then Now I noticed that the boot on the wheel side has collapsed and that some grease has come out So I removed the strap on the smallest diameter side and it started sucking air in I believe the boot itself is not torn What is the best thing todo to fix this?
Take a small nozzle from any spray can, like Brake Cleaner can, and insert it under the lip of the small cv boot end, reclamp it. This small nozzle vents the vacuum from inside the boot and keeps it from collapsing.
