My BMW 325xi front axles have a two-part boot design to fit the OE (GKN) 'hexagonal' inner joints. As installed on the complete OE axles they seem fine - BUT if used in a re-boot, SEAL the CIRCUMFERENCE before any grease touches that rubber ! There are probably 'best' sealants for this, but of what I can easily get, I would use Permatex Ultra Black. Swedecar, can you suggest better choice ?
MY EXPERIENCE in re-booting an axle with this style boot is that crimping the clamping ring DID NOT SEAL the boot - air could escape. I will need to re-do that boot - with grease already present, there is no easy way to go back without complete disassembly and cleaning. Thankfully in my case this is a 'back up' axle in case I need to replace a front axle again - my 325xi goes through front axle CV joints way too quickly, and it has has made me appreciate how good a job SAAB engineers did in specifying things like CV joint allowable angle to give good product lifetime.
