Axle boots tore prematurely? I replaced both inner/outer boots last summer

When finished you can just let it evaporate and the grease will be left in the bottom of the bucket.
I've also heard mineral oil works well, but guessing that's pricey too.

Can report the findings, but based on experience, they will last a few years to come.
More importantly than the boot type/composition, be sure to completely remove all of the old grease when re-booting axles. Some grease compositions don't jive with each other and can actually cause friction surfaces - and of course, make sure the boots aren't rubbing on anything in the full swing of the axles. Many f the lesser brands have exceptionally large bellows that may rub the shock during trailing arm swing.

I'm hoping it isn't much different than this: https://www.youtube.com/watch?v=-S-ofMoWsr0&t=114s
If there's an iX-specific DIY out there, I'd appreciate a link :)

This is disappointing seeing as I had them all replaced two years ago and have yet to drive the car since. Even more disappointing is the fact that I have two more full sets of the oem equiventlents as backstock some of them are even labeled as Ford as I believed the part manufacturer reused the same part on a focus years later. Would you guys think that giving the non BMW ones some sorta of soaking coat of a protectant would help soften them up? I would think it'd be worth a shot to try and prolong their life before buying the BMW ones. Maybe giving them protectant might help prolong the life of them. Any thoughts?Last edited by AWDE30; 10-21-2012, 10:50 PM.

FWIW I've never had the GKN boot fail on the outters or driver's inner. the passenger inner boot seems to last maybe 1 year though.

got the new boots in the mail saturday.....the OEM axle boots are pure rubber unlike the cheap ones I ordered from AutohausAZ which were hard plastic. Hopefully this time around it won't tear on me as easily as the GKN Loebro ones

I am almost positive the BMW OEM boots are a more rubbery feel. I haven't held both in hand but I do know the BMW ones are a nice rubbery feel.
