one, two, three, four! Rev up your engines! It's time for the Scotty Kilmer Channel Is your car making clacking noises when you
accelerate and turn, like this, now on a front-wheel drive car, that means one
thing, the cv joints are worn on the outside in their clacking, and we'll jack
it up to find out, then when we check inside, we can see the boot is wrapped
and all the grease has come out, so it's time for a new joint, but in this case,
we're going to replace the entire drive shaft with the new unit, these cars are
popular, they make tons of these whole brand new units that cost a lot less
than just the brand new joint itself and it's a lot easier to replace the whole
thing, than it is to take it apart and repair the joint, now in this case we're
going to Jack the car back down on the ground to get the nut off, because it's
an old car and it's probably going to be stuck and I'll show you a trick, first you
take the cotter pin out with a pair of cutters, off it comes, then we take off
the clip, then you get a socket that fits the nut, a cheater bar, and a giant piece
of pipe, then we put it on the nut, put the pipe on top of it, then pull, and when
you push enough, it comes loose, and now that it's loose, we can jack it back
up in the air and start taking it apart and now we'll stick a jack stand, so it
won't fall down and squash us, and we'll get the wheel out of the way, we'll take the nut off, use a cheater bar socket again,
and leave the nut on a little because we're going to hit with a hammer to try to knock
the tie rod assembly off, give it a few good taps, then off it comes, then we take the
bolts off that hold the strut to the assembly here, then it comes off, now if
you notice on the new axle shaft assembly, there's a bearing here, that's
held in on the inside on the frame of the car, so we have to loosen the bolts
that hold that and so we can slide the whole thing out, it has a bolt on the
bottom of it here, that you just remove, and there's a clip here that you get a
little pair of pliers and squeeze them together to snap the clip off, I use these
giant needle nose pliers and do it from the outside here, you can see the clips
right there, you just grab them with the pliers, and once you release them
they're loose and you can get the assembly out, and out it comes, and of course match them up
to make sure they're the same size, a lot of times they send you the wrong ones,
then of course slide it back in the hole, then comes the really hard part, you
have to snap that clip back in, it took me a good 15 minutes of wiggling, but I
finally got it in, then the shaft goes back into the axle assembly here, I do a
little bit of wiggling, but with enough wiggling you can get the bolts in, get it
nice tight, and put the tie rod back in, then put a new cotter pin in and bend it
over, so it doesn't come loose, and tighten up the big lug but that holds the
axle in place, put the cotter pin in there, then put on the wheel and we're
done, so next time your CV joint start clacking, why not fix them yourself, and
remember if you have any car questions just visit the Scotty Kilmer channel and
I'll answer them as soon as this tornado passes over.
