CV Boot seeping Grease ? SIMPLE FIX !...

Having a lift that changes the angle of the CV
joints, puts added stress onto the CV boot
clamps, and they will eventually stretch and
grease will seep out between the boot and the
other components which it is clamped around,
ie: shafts and ends...

So, to fix this, you have three options, one is to
pull the axle out and take the joints apart and
replace the clamps with the same closed factory
style clamps... OR, get an aftermarket open end
CV clamp and the special service tool to install it,
OR... Leave the axle in place, Pick up some hose
clamps, cut the factory clamp off and install the
new ones !...

My CV boots' were seeping grease from the boots
due to the OEM bands stretching out from the
increased angle of my CV joints due to the amount
of lift I have dialed in up front on my coil overs...

So, I put my 9mm(3/8") SS hose clamp on the boots
and cleaned up the area using brake clean and paper
towels, and it is holding good, nice and dry... ...

I tried the 9mm x 110mm-130mm clamp, but it
did not have enough threads, so I went to the
9mm x 80mm-100mm clamp, and it was a tight
fit, it worked mind you, but had no excess after
it was installed to be able to bend over the end
a tad so it can come loose... I did however find
the right one I needed listed at West Marine...

HERE are the clamps I got from my local West
Marine store... The ones located on the right,
NORMA 304 Stainless Steel Hose Clamps...

I was going by the tag on the ones I purchased
that were listed in METRIC, but the web site has
them listed in SAE, So here are the numbers from
there...

Size Hose Clamp for Large Boot end :
SAE - 9347493 - 3/8" 304 Stainless-Steel Hose Clamp, 3-1/2" to 4-3/8"...
METRIC - 9347493 - 9mm 304 Stainless-Steel Hose Clamp, 90mm to 110mm...

Size Hose Clamp for Small Boot end :
SAE - 9347410 - 3/8" 304 Stainless-Steel Hose Clamp, 1" to 1-5/8"...
METRIC - 9347410 - 9mm 304 Stainless-Steel Hose Clamp, 25mm to 40mm...

These clamps are a perfect fit for the CV boot
groove, and work excellent, not a bad item to
have in the trail/travel box... The edges of this
clamp are curved over a tad, so it can not cut
into the rubber boot, a BIG PLUS !...



To remove the OEM clamps, I unfolded the two
small side tabs, then lifted the clamp tab to
release the presure... I took a clippers and cut
the clamp off, since they are a closed circle...

EDIT : Added Images...

Here you can see how the 3/8"/9mm clamps fit
perfectly in the boot slots...



Here are a few more picts'...

Re: CV Boot seeping Grease ? SIMPLE FIX !...

That's exactly what I did this summer after doing Rubithon. I carry a spare set of those in my "spares kit" with a tube of CV grease....

GREAT post!

Thx, Bandi!

Let us know if you get any vibration or how they hold up in general.

My boots are OK for now...But a great item(s) for the tool kit...

Re: CV Boot seeping Grease ? SIMPLE FIX !...

No Vibes at all, I have been running the large
clamp for some time now, and just added the
small one today as I had a lil' grease seeping
out of the small end for a while... Since they
are mounted so close to the center of rotation
and weigh next to nothing, so it really would
not be felt...

Re: CV Boot seeping Grease ? SIMPLE FIX !...

I was just under the FJ Saturday, and noticed that I've got a slight seep at the small clamp on the passenger side. Talk about a well-timed post, thanks Bandi!

I'll pop over to the West Marine on 75 at lunchtime this week, and pick up some clamps, and replace the small ones for now. I'll also pick up some spares to stash in the tool box...
