Hey what’s up everybody dustin here with rocky mountain atv/mc and today i’ll be showing you how to replace the cv boots on a utv cv axle cv boots are what protect and retained the grease inside of our cv axles unlike many components on our utv’s and atvs they can begin to wear out over time and they will begin to crack or tear now once the boot that protects the

Seavey’s joint has torn you will want to replace it sooner than later as it can lead to further damage on your machine with that joint now exposed to the elements so it’s always a good idea to keep an eye on these and inspect them as often as possible so today we’re gonna show you how to replace the cv boots off of a polaris utv cv axle now the process that we’re

Going to show you here today can be applied to many you tvs and atvs with cv axles now as far as tools go you’ll just need some basic hand tools here we’ve got a hammer a pick some pliers some snap ring pliers and a couple tools here from tusk we’ve got our cv boot banding tool as well as the cv boot band cutters you will want to have some rubber gloves safety

Glasses racks and as well some contact cleaner as far as replacement parts are concerned we do offer a wide variety to choose from on our website we’ve got everything from oam to aftermarket for today’s video we’re going to be using the all balls cv boot replacement kit now these do come sold individually so when you pick yourself some up be sure to grab an

Inboard as well as an outboard to begin remove your cv axle from your utv or atv then we can take and place the inboard side joint into our vise with soft jaws and once we’ve got the axle secured in the vise we’re going to take our cv boot banding cutters we’re gonna cut off both of our cv boot bands now once you get the cv boot out of the way you want to inspect

The inside of the joint here for any type of dirt or water contamination if you have any of that present inside of the joint polaris recommends that you go ahead and replace the entire joint assembly then we can take a rag we’re gonna pull up on the joint and we’re gonna remove as much of the excess grease as possible i mean take our pick tool and on the inner

Diameter here at the top of the plunging joint we’ve got a snap ring that sits inside of here and i can remove the axle from the plunging joint remove the plunging joint from the vise then we can place our axle back into the vise wipe off excessive grease next we have a snap ring that retains the racing cage onto the shaft we’ll take our snap ring pliers remove

The snap ring then we can remove the racing cage now real quick i do want to point out that there is an orientation to this assembly the larger diameter is going to face towards the inboard part of the axle while the smaller diameter is gonna be facing towards the outboard joint now players again does not recommend that we disassemble the racing cage any further

As these parts do develop specific characteristics as they wear so we don’t want to disassemble that any further with our racing cage removed from the axle shaft we can now remove the cv boot and we’re going to flip our axle around to the other side let me take our cv boot band cutting tool we can cut the cv boot band we’re going to pull down on the cv boot pull it

Away from the joint take a rag and remove as much of the excess grease as you can now even if your outboard boot is the only one that is damaged polaris highly advises against disassembling the outboard joint here inside of there we’ve got a sir clip and in order to disassemble the joint you do have the strike it pretty hard with the hammer in order to disassemble

It and you run the risk of damaging some of the components in there because they are precision fitted as well they develop their own characteristic wear pattern so again even if this is the only one damaged do not disassemble this end of the joint just disassembled the inboard which is easiest and you won’t run the risk of damaging your axle alright so now we can

Flip this around so that we can remove the boot i mean take a rag we can clean up all the excess grease that we can alright so now that we’ve got our cv boots removed we can go through and clean all the components so clean up the plunging joint as well as the racing cage and the outboard joint now for this i’m just going to be using some contact cleaner and after

You get all the grease out and everything cleaned be sure to let it dry completely before you start the reassembly process now when it comes to cleaning the racing cage you do not want to disassemble any further than what we have shown here if you are to lose any of the ball bearings be sure that you can identify where it came from put it back in its location as

This component does develop its own specific characteristic wear patterns all right so once we get all of our parts cleaned we want to give them a good inspection to make sure that they’re in good shape still now when it comes to inspecting the race and kate you just want to look for any type of galling any severe damage if there’s anything wrong with it it’s

Definitely gonna jump out at you and you will see it also be sure to inspect this cage here for cracks if it’s cracked you definitely going to want to replace this assembly also inspect your plunging joint for wear as well check your snap ring and circlip to make sure that these are in good shape if they’re bent or damaged in any way you will want to replace them

And players also recommends that once we remove one of these snap rings we go ahead and replace it now when it comes to inspecting this joint again you’re wanting to look for any type of galling especially if there’s been any water damage or dirt that got inside of your cv boot if that’s the case again players recommends replacing the assembly now on all ball cv

Boots there is a difference between the inner and the outer cv boot now on the inner boot we’ve got three distinct ribs on the outer we’ve got four distinct ribs and if you’re still having some difficulties you can always match up the part number with our website to tell if you have a rear inner or a rear outer cv boot now we’re gonna take our outer cv boot we’re

Going to place it on to our shaft we’re gonna bring it down to about here next we can take the axle grease now in each kit it’s going to come with a predetermined amount of axle grease so once we put this in here you want to make sure that you get all of the contents that are inside of the packet inside of the joint start by filling the joint with as much grease

As you can and once you get enough grease on there you kind of want to work it down into the joint with your fingers to make sure that it makes it through to the other side all right so once you’ve worked the grease through the joint we’re going to take and empty the rest of the grease packets contents into the joint so once you get the contents of grease package

Onto the joint we’re going to take and clean up these areas here where the band’s are going to secure the boot to the outer diameter of our joint we’re going to clean up this landing right here as well as the smaller diameter landing all right so once we’ve got that cleaned up we can slide the boot down into place and when you’re sliding the boot into place you want

To be real careful that you don’t push any grease that might make its way into the landing where the boot band will sit so just be aware of that on the smaller diameter just sit down in its groove on the axle shaft all right so once we get the boot in place we’re gonna take it out of our vise and set it down on the table all right so now we can grab our bands here

Now you’re gonna have two different ones a larger one and a smaller one obviously the larger one will go on the larger diameter now when installing the bands onto the cv boot you want to be mindful of the axles rotation and which part of the machine it came from so this is our driver rear so our axle is going to be rotating in this direction now we want to be aware

Of that because once we get this installed onto the cv axle we want to make sure that we bend the tail of the bending clap back on itself that’s opposite the direction of the axles rotation this way we can ensure that it doesn’t have a sharp edge like if we were to install backwards that it’s going to get snagged on and rip itself off unlike an object of rock or a

Branch double check to make sure that the boot is fully on to the joint here on the outer diameter make sure that it’s looking good and then we can take our cb boot banding tool it’s got an opening here at the tip of it we’re gonna slide the tail in through there and then this part right here that rotates it’s got a slot cut down the center of it and we’re gonna

Place the tail of the band in the center slot just like that once we’ve got it set up in this position we can begin to rotate it and this is going to cinch down the cv band onto the boot now while you’re doing this you want to pay extra careful attention to the band to make sure that it seats in the rubber channel on the cv boot if they’re going to rotate this a

Little more to secure it now you don’t want to crank on this thing like super tight just enough to secure the boot to the outer diameter once you get it on there tight we’re going to bend it back on itself then we can begin to remove the tool and take our bending cutters cut it about here i mean take our hammer just kind of crease this edge that we folded it back

In on itself just right lightly not don’t hit it too hard we’ll take our pliers we’re gonna grab both of these tabs and fold them in on each other lightly tap on them with a hammer take your banding cutters and trim off the excess tail so that you have maybe about an inch left i’m gonna trim off the corners just kind of tap on the tail to make sure it stays down and

Out of the way now we’re going to repeat the same process for the smaller diameter but first we need to equalize the pressure that’s inside of here so we’re going to take our small pick tool you’re getting is a small flat screwdriver if you want we’re going to slide this underneath the boot then we’re just going to kind of lift up on it and this way we can equalize

The pressure inside of there all right so once you’ve done that we can now install the other band so now that we’re done and finished up with the outboard side we can now take the inboard cv boot we can place it on to our axle shaft with the small diameter first we’re going to slide this all the way down the shaft until it touches the other boot now before we

Install the racing kage we’re going to take just a little bit of our cv grease here we’re gonna coat the splines on the shaft all right then we can take our race and kage remember the smaller diameter is going to face towards the center of the axle and the larger diameter is gonna face towards the joint itself the plunging joint take these snap ring with snap ring

Pliers install it give it a good inspection to make sure that it’s fully seated then we can pull our axle out of the vise in place the plunging joint end back into the vise take some grease we’re gonna coat the inside of the plunging joint let me take the axles shaft place it into the plunging joint we’re going to install our circlet make sure that it snaps into

Place and give it a good inspection to make sure that it’s fully seated then we can take the remainder of our grease and fill the plunging joint put the grease packages contents emptied entirely into the joint we have the joint in and out several times work it around in circles to make sure that the grease is distributed ly throughout the entire racing cage of

The joint itself so now we’re ready to bring the cv boot down and connect it to the plunging joint before we do that we’re going to take some contact cleaner spray it on to our rag we’re gonna clean up the channel where the cv boot band will sit well we want to make sure that there’s no grease in here we’ll do the same for the smaller channel as well we’re gonna

Slide the cv boot down into place now when you’re sliding it on to the outer diameter of the plunging joint we want to make sure that no grease gets in between the boot and where the cv band secures to it so once we have to there we can pull pull it out of the vise and set it on the table and secure the band’s now before we install the smaller diameter band we

Need to equalize the pressure inside of the joint here now to do that we’re going to take our pick tool we’re going to insert it in between the axle and the boot being mindful not to damage the boot we need to create a gap between that fitting and then we’re going to pull out on the plunging joint all the way and this is going to equalize the pressure inside so

Basically you want to equalize the pressure with the cv axle and the position that it’s going to be in for the longest period of time so we’re going to pull out on it equalize the pressure and then we can secure the last band and that’s it that’s all there is to it when it comes to replacing the cv boots on your cv axles now if you have any questions as to what
