I was reading mixed reviews about these kind of cv tool product. In the end, I thought I would give this a try, and then return it if it didn't work. I chose this because it came with a sample stretch boot that I could compare/assess (which I could also use someday) the tool's potential. Upon comparing the boot, the sample stretch boot was close enough (in terms of elasticity) to the one I already purchased which is a different size. It worked with my Flexx boot FB3002 (Astoria). One thing is that this tool should only be used with those "stretch" cv boot kind, the one that is designed to stretch into a funnel. There are several brands that sell these kinds of stretchy/elastic boot. This tool came with air tool nozzle/connectors, some small rubber washers (still not sure if I correctly used the rubber washer/gasket for its purpose), and a pin (which I don't know what it's for). So, what I did is I used the small rubber washer/gasket by inserting one into the the tool air hole before I threaded the air nozzle. I'm thinking that this gasket will be sandwiched by the tool and nozzle as it is tightened enough. I also tefloned the nozzle threads. The housing is plastic so be careful not to overtighten and/or cross-thread the nozzle. Also, made sure tool was cv boot loaded before trying/testing because didn't want to risk breaking any seals/components pressurizing the tool without any compression load. Lubed claws with vegetable oil, inserted cv boot, and ...zoila, it worked!!! (My operating pressure was set to 95 psi.) I also openned (pressurized) it just enough to get it into the axle joint, since I don't want to over-stress, and over-stretch the boot. Once in, then situate the axle joint to be able to close the claws as much as possible. But then it still takes a bit of an effort to slide it out of the claws because you can't close the claws completely when the axle joint is still in it. But it sure is easier sliding it out of the claws into the shaft, than, sliding the boot through a funnel (which I've tried and considered it hopeless before purchasing this tool)!!! I mean you have to take the axle out to use the funnel based on my attempts. So this tool is heck of a lot better than taking the whole axle out of the vehicle, ...especially if it is the passenger side (or the long side of) the axle!!! Woohoo...!!!

Is not able to open up rubber or OEM boots. Boot that comes with product is very thin and flimsy compared to quality C/V boots

Cuando tu la ingresas al cv axle no Sierra perfectamente pero es mejor que pasarlo sin estirarlo

The included CV boot is made of a very soft material compared to standard boots. The tool only works with the included soft rubbery boot which makes the tool useless to me.It seems well made but just didn't have the umph to spread other boots. No max air pressure listed, was reluctant to go much past 100psi. Would probably need like 150psi+ to do what I needed to do.Bottom line is it didn't do what I needed to do. Returned it.

I bought this with high hopes. The downfall is it will stretch the boot out that comes with it. (Thin rubber) However it won't stretch the thicker boots no more the a inch and a half two inches if your lucky. (Axel boot for one of our quads ) Not even close to fit over the intended axel. Very disappointed.
