It's time for the Scotty Kilmer Channel
is your vehicle vibrating when
you accelerate like this,
shaking all over the place, well a car that really start shaking when
you accelerate, has some type of the drivetrain problem, so it could be in the
transmission, could be in the driveshaft, could even be in the CV joints, we'll Jack
it up and check, wheels up in the air, we'll get out the magic carpet, and crawl under,
then we grab the driveshaft and wiggle it, we can see the joint is broken in the
back, we do the universal joint on the driveshaft, so what's happening is this,
when the joint is worn, as you accelerate, all the power of the car goes down the
driveshaft, and since it's worn, then it wobbles back
and forth it makes the whole vehicle shake, now we have to take the driveshaft
off to change the joint, so we take the four nuts and bolts off here, and since
transmission fluid is going to leak out when we pull the shaft off, you get a
drain pan and stick it under there, we just unbolt them all, you take out
the last nut bolt, and the driveshaft just slides down and out, and as
you can see in here, this ends all loose and the pieces are broken inside, now to
get it off, you need one of these special universal joint tool kits, they only cost
about 30 bucks if you go online, they're not that expensive, but you need the tool,
now if you look inside here, you'll notice there is little clips, you have to pry
the little clips off, we'll turn it on the side, now you can see the clips, they
just pry out, then you place the driveshaft on the tool, get the wide end, stick it
over here, and start hammering it, and when you it hit hard enough, the
end comes out, then you flip it over and do the other side,
and off it comes, then we do this side,
now if you notice my replacement one's better, the old one had a grease joint
inside that's almost impossible to get to, this one, has a grease joint that you
put in the end cap when you're done, so you can easily grease it, and it'll last
longer won't dry up, like the other one did,
now I put the new one on, we'll take two of the ends off, they just slide off, then
you slide this side in first, then stick the cap in and make it a little snug, then you
get a little hammer and tap it part of the way in, then you put the other cap
in and tap that a little, then you pick it up and put it on this end of the tool, so
this end is flat, then use the small end of the tool, put it on the top, and tap it in,
then you get the clip, snap it inside, pretty tight, so you get a little hammer
and tap it, then you turn it over again, and do the other side, and then put this
little spring in,
then you take these ends off, slip the the yoke on,
and put the end caps in, and tap it like before, then get the small end of the
tool and finish tapping them in, put the ring on,
and then do the other side, and slip that ring on,
and of course, don't forget the grease fitting,
get your grease gun, and grease it up,
then you roll the driveshaft back in, you slide the driveshaft back into the
transmission, and bolt the other end up, get them nice and tight, and now when you pull on
it, no more clunking, and if any fluid came
out in the pan, put it back in, but in this case, nothing leaked out so we don't
have to put any back in, so the next time your vehicle starts shaking when you
accelerate, why not fix it yourself and remember do you have any car questions
just visit the Scotty Kilmer channel and I'll answer them as soon as I'm done
recycling myself
