I don't think it's installation or angle.
I have seen too many aftermarket rubber pieces fail way too early.
Ball joint/tie rod boots, strut mounts, window seals, you name it.
Makes you wonder sometimes when the OE stuff will go 25 years in some cases
with no cracking.
Today I'm replacing the CV boots on a 21yo, 175k Toyota, 3 of the 4 are
still not blown out.  This car has had one owner, she keeps all records and
boots were never changed.
We'll be lucky if the replacements last half that long.

Because it doesn't need to be serviced at this interval! I just rebuilt some
with a friend that were original to the bus and have never been serviced (
he's the original owner). 140,000 miles and 26 years of use, and the boots
we took off were fine!
So why do mine suck?
