Not Again!!!

So I am underneath my coach changing the oil and taking care of a few other maintenance issues (more on that later) and I notice a bunch of grease on
the trailing side of my right fender liner.  A little feeling around revealed another torn CV boot.  I replaced these about 4-1.2 years ago, maybe
25,000 miles, and here one is bad AGAIN!.

Fortunately, I have another shaft and new bolts to replace it with, but it is a heck of a lot of work (just venting)  The spare shaft has one of the
old 'blue boots' on the outer CV that Dan Gregg gave me (used) several years ago.  Those seem to last.

What is the average interval that the rest of you guys are having problems with these newer boots?

The Unifit black boots have more pleats so don't pull off as easily. Have held up for me.

Carl,
I've had the same problem but only worse. I only got about 1 1/2 year out of 2 rebuilt axel shafts. And both failures were on the outer boots.
I got the new outer boots from Jim K, and they seem to be working fine.
The old blue super boots were the best. It would be nice if they were still available.
Scott.

I put OEM style boots on my coach in 2008 when I rebuilt my entire front
suspension and steering on my 1978 Royale. I have a "Band-it" clamp making
tool, and it works well. My boots are still intact.
But, there is a trick to installing them. Absolutely have the large
end of the boot completely free from grease as well as the inside of the
boot. Clamp the snot out of the big end, and use a plastic zip tie on the
small end. It will move on the shaft instead of twisting the boot and
stressing it beyond the point of elasticity. They might seep a bit of
grease if you have insisted upon overgrazing the joint. Only use the pouch
of that Black, gooey, nasty, lube stuff that comes with the new boots. It
is formulated for constant velocity joints. Just what I do.

All that makes good sense Jim.  I think, from the distortion on the boot, that it has sipped (spun?).  This shaft came initially from Applied GMC and
was briefly on a local friend's coach that he later converted to the Manny 1-ton.  I think it had, maybe 100  miles on it before I bought it from
him.

I guess I can't complain about having to replace them every five years or so, but this is the third time and it is starting to get old.  Hopefully the
other shaft I have, with the blue silicone 'super boot' will last longer.

Take a very close look at the cotter pins on the castellated nuts close to the axle.  One of mine died on the way home from L.A. and I found the end
of a pin sticking straight down.. ever hard bump drove it into the boot, looked as if.

There is something to what you say about some boot setups lasting very
well, and others giving very poor service.
I have one regular customer that I did an engine swap for just early
last year. He had a torn boot on that coach when we did the swap, so I
replaced both the axle assemblies with reconditioned ones from a vendor
(not Jim K.) He came back 2 months ago for an oil change/lube service, and
to upgrade an engine oil cooler. Upon checking the boots, one was torn. So,
we yanked the axle assembly, cut off the old boot, and disassembled the
outer joint, cleaned and inspected the joint, re lubed it and installed a
new Dorman boot, using Band-it clamp on the big end, and zip tie on the
small end.
This in not my first rodeo where boots are concerned, been wrestling
with them since the swing axle VW's were popular.
I suspect, but have no empirical evidence to support my suspicions,
that ride height settings might have an effect here. I really don't know.
Some last well, and some do not.
I know that there exists out there a pneumatic tool that expands the
small end of the boot enough to install the boot without disassembling the
joint. That is stretching the heck out of that boot. Could this be a cause.
Perhaps.

Also good advice on the cotter pins and the ride height.  I don't think either of those are the problem, but I'll check both.  I haven't paid much
attention to the ride height since I rebuilt the front suspension 10 years ago.  It's probably time to double check it.

Some of these coaches have bump stops that limit how far you can turn the
steering wheel, and some will turn until the power steering pump groans in
protest. Might be early vs late or something. Dunno' for sure.
