Works very good.
Surprisingly, it works exactly as advertised. Spraying a little cooking spray on the plastic slides lets the rubber glide right down. If you don’t have cooking spray, Pledge furniture polish works just as well.

Worth the money
Saved me some $$$, a bit of a challenge to slid the boot through the cone but worked great. Highly recommended

It works. Here's how I did it.
All things considered, it went on pretty easy. Here's how I did it: Get your axle so its all set and in front of you. Put the cone in place over the axle. I covered mine with cooking spray. Turn the boot inside out and give the mating surface that will come in contact with the cone a good coating of spray as well. I took a paper towel in each hand and grabbed either side of the boot and pulled the crap out of it and it went on not too bad. I struggled a bit until I thought to use the paper towels. Once its on, work it until its right side out and then I attached the small clamp first. I had to play with it a bit to figure out what ring I was going to use for the clamp and where I would trim it. Once I determined that, I kind of made an opening at the top and poured all the grease I could into it. Then I attached the large clamp and then trimmed it with a blade. Really I'd give it 4 1/2 stars if I could because its a great idea for certain applications and works. However when I removed the original Toyota boot it was at least double the thickness. Wish it was thicker and application specific so you dont have to trim it. Hoping it lasts as long as the axle.

A good idea that does not work well
The boot was far too difficult to to squeeze over the provided cone even with the pledge as shown in the video. I do not recommend this product!

Agreed with everyone else, that was really hard
Make sure to clean the rust on the outer CV axle before you tear off your old boot. This will minimize the chance of debris getting into the grease and bearings. I lubed everything up with grease and thought it'd be clever to pre-stretch the boot over the cone before sliding the boot over the CV axle. Don't do that because the boot will keep sliding off the cone cause there isn't enough friction to keep it on. Go to directly trying to slide the boot over the axle. I was doing the outer CV, but I found it was easier to do the small diameter first. As a smaller individual, (125lb) I had my back against a wall and basically used my leg, core, and a paper towel (for better grip) to push the boot through. I did try letting the boot sit in hot water, as well as the cone and grease, but I think it's not helpful if you're not super fast. Everything cools down by the time you have a successful attempt. Overall, boot is of good quality, but it's a b#&$ to put on

Instructions would be nice
I suppose this is like everything else, the first time you do it is a challenge but it would go much more smoothly the second time. That's where instructions would help immensely to give you a fighting chance at success the first time. I was doing an outboard CV so the first question was do I turn it inside out and install the big end first or try to install the small end first? There are videos showing doing it both ways and I couldn't find anything specific to this brand. I chose to turn it inside out and I think I'd do it that way again. The next question was what to lubricate the cone with. Some videos say Pledge, some say oil, some say grease, some kits come with the cone lube. I started with Pledge because it seemed like it would be the least messy but made another mistake by only lubricating the cone and not the boot. The boot stretched tight over the cone wipes off the lubrication and then you're trying to slide the small end over a dry cone. SPOILER ALERT: That doesn't work. After lubing the boot and the cone for try #2 I ran into the next issue. The boot actually slides up the cone easily enough but the cone isn't big enough to clear the CV joint (see pic #1) and the boot stopped sliding when it hit the joint. I fought and fought and finally got the leading edge of the boot into the retaining groove on the joint and it wasn't going any farther. By now the Pledge was gone and the boot was dry on the cone. I was able to get it removed and regrouped for try #3. I went for a little more permanent lubricant and chose spray silicone and put it on both the boot and the cone. This try got the boot completely off the cone but the small end had barely cleared the tone wheel and it was NOT going to slide over the joint. At this point boot #1 gave up the fight (see pic #2). It was also about this point I wondered if I was going to have a vehicle down while waiting for a new half-shaft, but I had another boot and I'm not a quitter so I strategized for try #4. This was all or nothing so I went with grease. I liberally greased the outside of boot #2 and then turned it inside out and greased the cone - and then that little voice in the back of my head that said you need to do something about the rusty CV joint OD got loud enough that I finally listened and sanded down the joint until it was as smooth as the cone. This time the leading edge slid easily over the CV joint but the small end stopped just past the tone wheel again. With the cleaned up CV joint I was able to work the small end over and the worst of the battle was over. I wasn't off the struggle bus yet as I couldn't get the boot long enough without it collapsing because it would seal to the shaft and pull a vacuum when slid out to the retaining grooves. I was able to ever so gently insert a radiator hose pick in the small end as it was slid out so air could get in and the boot retained its proper form. My final blunder wasn't discovered until assembling the axle back into the knuckle and realizing the boot was too far on the joint and the clamp interfered with the casting. Thank goodness the kit included everything needed to do 2 joints because I used virtually all of it to do one. I rated the product 3 stars when there's nothing wrong with it and that may seem a little harsh but the lack of instructions meant a 1 hour job took half a day and paying for enough to do 2 joints is only enough to do one. Folks that do this for a living don't need them but home gamers only do a few in their lifetime and would most definitely benefit from them. Not having instructions affected the value of the product for me. I have four more of these to do on a pickup and after having been through it and knowing all the tricks - I'll go with split boots.

It worked perfectly!!!
It made me happy to remove my headaches from Camry 2005 CV Axle boots' problem. So great!!! One thing, boots are very flexible so it might be tear easily.

No issues with them, able to install with no problems, and most everything you might need is included (depending on the exact machine you are installing them on).

Après l'ajout d'un lift kit de 2 po mes boots de cardan OEM on fendu et ouverte du a l'angle devenu trop gros , je recommande fortement ce kit , ces boots la son souple , épaisse et plus longue , sa regler mon problème , et avec le cône lorsque fait de la bonne manière ces vraiment facile à poser
J**L
J'ai dû remplacé une boots de cardan suite a une perte de graisse,j'ai vu ce produit et la vidéo ma convaincu. j'ai une base en mécanique donc pas de problème,j'ai remarqué que le cône que j'ai reçu était quand-même gros pour le cardan,je l'ai coupé environ la grosseur que j'avais besoin. Bref avec une canne de pledge et un peu de force le tour est joué. PS bien lubrifié l'extérieur de la botte car elle tourne sinon ça prend 2 minutes

Did the job correctly without removing complete shaft, saved me lots of time

One boot ripped on manufactured seam first try with a fully lubed cone. Tried to contact supplier but never received a reply. Website they have linked to seller is a shoe factory. The second boot did work which is why it is receiving a 3 star. However I’m not impressed with 0 customer service.
