Rev up your engines!
It's time for the Scotty Kilmer Channel
today I'm going to show you how to replace a
leaking axle seal on your car, now once we took the rear wheel off this Jeep, we
can see there's all kinds of grease on the backing, that's because the seal
inside here is leaking, and we have to replace it,
well since the brake calipers in your way, first we have to take it out of the
way, by taking the two bolts off that are on the inside, now these are often on super
tight, so get yourself a nice long cheater bar and a socket, and then pull
like mad, then you can get the two bolts off, then the brake caliper just
taps off, and the brake rotor slides off, now we have to take the axle assembly
off, there's four bolts that hold it in, and they're hiding on the backside in
here, we just take the four bolts off, you just unbolt them all from the inside,
there's four of them, and there's the last one,
and now comes the hard part, we have to get the hub out, and you need a slide
hammer, now you can buy one, rent one at places like autozone will even loan you one free if you
buy the seals from them, you just stick the end of it on here, put three of the
lug nuts on, just need on snug, then you just whack the slide hammer
until the axle comes out, out it comes now, in most car designs,
the seal is inside the shaft, right in here,
but of course, jeep has to have a stupid design, their seal is right here, behind
axle bearings, so now we got to take all this apart, and buy new axle bearing just
to change the seal, so they turn something that used to be about a
15-minute job, into one that's going to take hours, and you're going to have to buy
a bearing, and a seal, because it's going to ruin the bearing when we take it off to
get to the seal, great engineering there, and now comes the fun, we get to
grind the old bearing off to get the new one on, to get the seal behind it, the off
comes the ring, that holds it in place, and you have to hit the end of the bearing
off, slide that out of the way, and then slide everything else off, just to get to the stupid seal, then you get the new
seal on the plate, get the plate on, the seal on here, then you slide the bearing on,
you get the bearing collar and slide the bearing collar on, now you got a choice ,you
can use the Machine press if you have one, but just a big piece of pipe to
slide over the top, we are going to use a pipe,
then we get a big hammer, and tap the plate, until the bearing slides back in
place, then you slide the axle back in, and wiggle it until it goes in place, then you
tighten the four backing nuts, then get some cleaner and spray all the grease
off that's leaked all over the place, put the brake disk back on, then bolt the brake
caliper back on, bolt the wheel on, and don't forget to
fill the rear end back up with fluid for the stuff that leaked out, just take out
the drain bolt and fill it up until fluid leaks out of there, all that work
just to change this little seal, engineer's could have built it a lot better
than this, and remember if you have any car questions just visit the Scotty
Kilmer channel and I'll answer them as soon as I'm done opening this coconut
