one, two, three, four!
Rev up your engines!
It's time for the Scotty Kilmer Channel, if your car is making a humming sound that
gets louder the faster you drive, then today's your lucky day, because I'm going to
show you how to tell if your wheel bearings are bad, now in this case the
noise is coming from the back, it sounds like it's behind me, so we're going to Jack
the car up in the air, now it sure sounds like it's coming from this wheel, so
let's pull on it, now unfortunately it doesn't have any play, it doesn't wobble
when I pull on it, but that doesn't mean that the wheel bearing isn't necessarily
bad, many times wheel bearings will start to wear out and they won't have any play
but they start to make noise, so you have to pull off the wheel and check them, now
the wheel bearing is inside here, but we have to take the brake off to access it
so we'll get a wrench a socket and a hammer and whack off the brake, there's
two seventeen millimeter bolts on the back, you just put this on, and hit it a few times,
so you can take them off, and off it comes, then just pull off the brake disc,
and get a screwdriver and pop the bearing cover off, then get a big socket
and a cheater bar, that will fit over the bearing bolt, and put it on and pull like
mad, the off comes the whole bearing assembly, now if you look closely inside this bearing
assembly, you'll see there's little flakes of metal here, the metal is the
bearing wearing out so we know the bearing is on its way out needs replacing,
we should have seen just pure grease
inside there but, since we see little flecks of metal, we know the bearings
coming apart and it's time for a new one, and in this case the new bearing comes
as an entire assembly, the only thing we have to change are the studs that hold
it in, and the tone ring for the ABS, so on the old hub we got a hammer out the
studs, and change this tone ring for the ABS, to get the studs off, you just screw
one of the little bolt on and whack it a few times, then you take out the bolt and
there it is to use over, then we get a drift chisel to hit the tone ring out,
and off it comes, then you get to new bearing assembly, put the ring on, and tap it
back on, now these hub bearing assemblies come pre-greased,
so you don't need to do anything except put them on, they just slide right
on, then you put the bolts on, tighten it on, and then with a drip chisel and a
hammer, hit the little edges so it locks into place and now comes the tricky part,
you have to stick the studs back in, so you get a stud and a larger bolt that
will fit over it, and the regular bolts that screw it in, then you put the stud
in from the back, put the spacer bolt in, and the regular bolt and tighten it up,
then with your socket as you tighten this up, it pulls the bolt in and holds
it in place, once you get all the studs on, put the brake disc on, then bolt the
brake caliper back on, get it on nice and tight, and don't forget to tap the
grease cover back on, then the tire goes back on and we're all done, and down the
road we go with no more roaring sound coming from the back, and remember if
