How To Replace Front Wheel Hub Bearing Volvo S40

the next thing that we're going to do is  move along to removing all of our lug  nuts and then the wheel  now that the wheel's out of the way  let's go ahead and remove our axle bolt  right here  take a punch and a hammer come right  inside where the axle is and break it  free from the bearing  now that we have the axle bolt off of  there let's continue on to removing the  flex hose from its mounting bracket  right here  now let's follow that hose down and  we'll remove our two caliper bracket  mounting bolts  start that in a couple threads  let's hang it so it's putting no  pressure on the flex hose  remove the rotor disconnect the abs wire  from your abs sensor  just going to press on the center tab  and then remove it,neybolt.com,  inspect the wire make sure it's in good  condition and set it aside  let's remove our lower ball joint nut  let's leave that nut on there just a  couple threads so we can break the ball  joint free  once it seems as though it's moving go  ahead and fully remove the nut  remove the tie rod end nut  leave that on a couple threads let's  give this a couple loving bonks  all right  separate this from the front of the  knuckle let's go ahead and remove this  upper bolt it's going to come straight  on through  now we need to go ahead and spread this  area right here to do that i'm just  going to use a pry bar i'll give it a  couple loving bronx just to help break  it free  while it's spread go ahead and spray in  some penetrant let's pull down on this  control arm  we're going to separate the ball joint  from the knuckle  let's take our hammer and hit right up  along the top of this knuckle right here  that's going to bring this down  you want to be very careful not to  damage your axle or of course your ball  joint boot  let's get this to the press now we're  going to go ahead and have to try to  press the wheel bearing out of the  knuckle area here

 you're going to see you have your abs  sensor that comes right on through  you want to be very careful not to break  that by pressing this out  commonly if you wanted to you can come  up along the top right there  remove that bolt and then just give this  a couple wiggles and you should be able  to pull it out  if yours is very rusted like ours more  than likely it's going to break  so i'm going to try to do it without  actually removing the sensor  with the knuckle over at the press the  next thing that we need to do is start  lining everything up essentially i want  to be driving out  the inside area of this bearing so it  goes out through the outer portion of  the knuckle itself  looking underneath this area you can  tell that i have it supported  by where the actual caliper bracket area  is and of course where the tie rod end  arm is that's going to make it so this  is supported and it's going to make it  so i can push out the actual hub itself  so i'm just going to take a socket that  fits right over this hub area here  and then of course i'll take something  that takes up the space and then we'll  start pressing this down  you want to make sure that you have hand  and eye protection at all times  now let's carefully start pressing this  down  there it is friends now before we can go  ahead and insert our brand new bearing  of course we're going to want to make  sure that we clean up this entire area  make sure that you don't have any debris  inside this area especially all the way  down where the bearing is going to press  into  aside from that double check your abs  sensor make sure that it's not damaged  in any way  if it is now is a perfect time to go  ahead and replace it  now it's going to be time to get ready  to install our brand new hub and bearing  make sure you notice the way that i have  this set up i have a block that's going  along the back side of the knuckle  essentially just kind of holding it  still so it's not going to move i also  want to make sure that i don't have  anything anywhere near my abs sensor  let's go ahead and take this we're going  to line it up  and when we start pressing this down we  want to make sure that we're pressing it  down as straight as possible if it goes  off kilter you could potentially damage  the bearing the knuckle or both  with this as straight as possible let's  continue on by pressing this down and in  now i'm going to continue pressing this  until i feel as though it just barely  bottoms out you don't need to go too  much further than that  okay right there i can feel that it  doesn't want to go any further  that means i can stop

let's release  pressure  now we can remove this from the press  and we're going to give this a nice spin  make sure it spins properly  looking at the back side of the knuckle  you can tell that the bearing's exactly  where it needs to be  it's not hitting up against the abs  sensor in any way and it looks like it's  functioning properly  before we go ahead and put this on the  car pay attention to the inner area of  the knuckle where the strut's supposed  to be  make sure you clean that out of any  debris also the strut itself clean up  the shaft where it goes into the knuckle  now ,wheel hub bolt,we can continue on by getting this  onto the car  start the ball joint stud in there  start on the ball joint nut snug it up  torque the ball joint nut to 52 foot  pounds i'm going to use a pry bar  carefully come through the wheel bearing  itself to hold it from spinning  and i can hold this and torque it  let's apply some copper never sees into  the splined area of the bearing  we're going to line up the axle with the  bearing at the same time as we start  lining up the knuckle  with the strut let's slide it all  together  line this up  now i'm just going to wiggle this around  and essentially we want to make sure  that the back side of the knuckle the  slot on it at least is going to line up  with this area on the back of the strut  now let's carefully apply pressure  underneath the control arm raising up  the knuckle so that it lines up properly  with the strut itself  now let's put our pinch bolt in there  make sure that you use a little bit of  red thread locker on the threads  now let's continue on by bottoming out  this bolt and then we'll torque it to 66  foot pounds  release the pressure

 let's get our sway bar link back on here  with of course the abs wire bracket and  then the nut  let's torque this to 37 foot-pounds  let's reconnect our abs wire we're gonna  press it in and listen for a click  there it is give it a little wiggle make  sure it's secure  insert your outer tie rod end into your  knuckle  put the nut on there we'll start it on  bottom it out and then torque it to 37  foot pounds  now it's going to be time to put our  rotor on obviously our rotor is going to  need to be replaced but that's a video  for another day  what i would recommend is to clean the  entire mating surface on the inside  portion right here you want to make sure  you have no debris in this area where it  mounts up against the bearing  apply some copper never sees to the  mating surface  slide your rotor on use one of your lug  nuts to hold it so it can't wobble  around while you continue working  make sure you clean up the threads on  your caliper bracket bolts  apply some red thread locker and then  let's get ready to install the caliper  now let's bottom these out and torque  them to 88 foot pounds  now let's get our axle bolt in there  it's recommended to make sure that you  use a brand new bolt  and i like to use a little bit of red  thread locker let's bottom this out  then we'll torque it to 26 foot pounds  and then we'll turn it an additional 90  degrees  to be able to torque this you're going  to notice that this is going to want to  spin  i just use a pry bar coming straight  across the studs down to the ground to  prevent it from spinning  now.
