Hello, John Talley here with Partzilla.com. Today I'm going to show
you how to change out the front ball joint on our 2015 Polaris RZR 900S.
Pretty simple to do. Just want to lift up the machine, get a couple of jack stands
under it, grab a couple of tools, and then I'll show you how to get it done.
Alright guys, this is going to be a skill level 2, but don't be afraid of it. It's
not going to be that challenging. Let's go over some of the tools that you're
going to need to pull this off. On the socket side, just need a 15 and a 19
millimeter, maybe a 3/8 extension, decent 3/8 ratchet, 15 millimeter wrench, a good
pair of circlip pliers, breaker bar, and a torque wrench that at least goes up to
120 foot-pounds. Gonna need that to take care of the wheels. Alright, as far as
the parts you're going to need, if you would, reference our exploded parts
diagrams. It gives you a very clear image of how things come apart and more
importantly how it's going to go back together. Now remember, when you order
this particular joint you also need to order the circlip that is associated
with it. So once you've got your tools and your parts together we can go over there
and I can show you how to do it. Alright guys, so we have the wheel out of the way,
let's go ahead and start with the knuckle itself and it's just a pinch
bolt that goes all the way through. 15 millimeter on either side. When Polaris
sends these out they've already got Loctite on them, and they want you
to replace this bolt and nut. I think that's a little excessive. All we're
gonna do is just put some red loctite on it when we reinstall it and just reuse
the bolt. Alright, and that will just drop straight out. Alright a little bit of a
confession here. Does this ball joint need to be replaced? No it doesn't. But
there are a lot of them out there that do, that's why I'm doing this operation.
What usually happens, something gets up in here,
it pierces that out of rubber boot and then contaminants get inside and all
that starts grinding around and that's like you know, putting sandpaper in there.
So it will eventually destroy the the joint itself. And the way you would feel
that is to get the the vehicle lifted up, and grab the wheel and if you can rock
it back and forth, it's probably one or both of your little knuckle joints here.
So next up we need to go ahead and actually unbolt it from its pivot points
up here on the frame, and then we're going to carry it over to the press, take
out that circlip and then press it out. So let's get these out next.
Alright guys, chances are you're not gonna run into the problem that I have right
now to get out this front one, it actually pushes out toward the front of
the vehicle. Well guess what? I've got this big bumper in the way. So I'm gonna
go ahead and loosen up this other one in the back and then I have to take the
time to go ahead and remove that bumper so I can get out the front one. So this
will take me a little bit longer. Alright so we've got that out of the way, now we
can remove our frame bolts up here. There we are.
Alright, let's head over to the bench, get that circlip out of the way, then we'll
get it pushed out. Alright next, get it over to the press and press it out. Let's
see if we can hold this in place and just drop it into that socket. A fair
amount of pressure to do this. And there she is.
Now, just grab the new one press it back in. Alright, success. let's go and get that
snap ring back in. Alright we've got the circlip in place. Just make sure it's
down off all the way in that groove. This one looks good. So let's go get it back
on the machine.
Alright, when you're doing this, make sure you didn't lose that washer, and it
actually goes on this side of the bolt.
Alright let's get these snug back down and then we'll torque them. Alright we're
taking this to 42 foot-pounds. This one's a little bit tricky here because we
actually should technically have our torque wrench there. Well that's not
possible, so we're going to torque it from the backside. Is it going to be off
a little bit? Well yes, but it'll be at least 42 pounds over on
this side. We're just gonna get just a tick more. When we push the A-arm bushing
up inside, we want to have the bore lined up where it'll end up intersecting
with a bolt like that. That's actually where it's going to
catch and go through. Alright we're just gonna get this to line up where I
can see that kind of crescent moon. Push it through. Polaris actually wants you to
replace these bolts, I don't think that's really necessary. What I do feel is
necessary is to put some red Loctite on it. Snug it down, and then we're gonna
take it to guess what? 42 pounds. This is the same type thread and pitch bolt as we
used up there, that's why it's the same torque value. There it is. Alright I always
start these by hand, otherwise you have a chance to cross thread them. Alright,
we've got a Snap-On impact wrench and I want y'all to pay attention to this. I'm
gonna use this to run them in. Now I bet you just run off and jump on the trail
now wouldn't you? Well guess what? These take a hundred and twenty foot pounds
per. Alright I'm gonna have somebody jump up inside, hold the brakes. Let's see
how much more we have to put on it. See?
Well alright guys, that pretty much wraps this one up. Listen, if you need any of
the parts that we used to do this, why don't you come see us at Partzilla.com and we can
get you taken care of. If you have any questions or comments,
