Rear Wheel Bearing replacement concerns?

Hello,

The outer bearing should not have just fallen off; it is tight on the hub held in with a spacer ring. See image 1 below
Fit the new races as these are machined as a set with the bearings

How to procedure

1. Jack up rear wheel and insert jack stand.
2. Remove lug nuts and wheel.
3. Unbolt 2 13 15 mm bolts that hold the caliper assembly to the hub carrier. Remove the entire caliper assembly in one piece, no need to remove pads, etc.
4. Remove rotor from hub, it simply pulls out away from the hub.

5. No need to remove parking brake drum pads.

6. At the bottom of the hub carrier there is a bolt. This not only retains the hub/carrier assembly, but also controls alignment. Hark the bolt head flange and the carrier body so you can align them in the same position on reassembly.

7. Loosen the bottom bolt. Do not remove, just loosen.

8. You will need a hub puller. Remove the nut from the center of the hub (27mm). Pull the hub out. As you do this the carrier assembly will begin leaning out towards you, rotating downward.

Once you pull the hub, the half shaft is now free, pull it up and out of the way. ( I used a small bungee).

9, Use a socket or punch and insert from the outside (wheel side) and tap out the wheel speed sensor ring (looks like a gear with teeth on the outside. Once the carrier rotated downward you can see it by looking down into the backside of the carrier).

10. Pull the seals and inner bearings from the carrier. Note which is which. They are different.

There will be a tube type spacer in the center of the carrier between the bearings. Note its position, the inner bearing has a smaller diameter face, the tube has two different size ends, each corresponding to the bearing is faces. See image 1

There will also be a small washer (shim) against the inner face of the outer bearing. Do not lose it.

11. Now clean the inside of the carrier.

12. You will see a channel cut out of the carrier between the two outer bearing races. Use a punch and set it into this channel get to the back edge of the bearing race and tap it out with the punch and a hammer. There are 2 channels 180 degrees apart. Tap one side then the other and the race will come out. Repeat for the other side going in the opposite direction. See image 2 and 3. Take note of installed race depth, compare before and after

Installation is the opposite of removal.

1. After tapping the races in, install the seal then bearing on the hub shaft.
You will need to tap the outer bearing home on the shaft. See image 4

2. Install the hub into the carrier and seat the seal into the carrier. Let the carrier rotate downward. Use a wood block to set the lug nut studs on. They will now be facing straight down.

3. You will need to drop in the spacer and shim from the inside (now facing up).

4. Now install the inner bearing. Drop in onto the hub shaft and tap it home with either BIG socket, or a punch.

5. Install the inner seal

6. Drop the wheel speed sensor onto the hub shaft tap it onto the shaft and make sure it is seated.

Once this assembly is in place, make sure there is no play by trying to pull the hub out then pushing it back in, there should be no play.

Make sure to grease the bearings before installing. The same for the seal lips.

7. Rotate the assembly up and insert the half shaft inside the hub. When the shaft stops, start rotating the hub to align the splines of the hub and half shaft. The half shaft will then slide all the way in.

8. Install and tighten nut.

9. Align bottom bolt to mark and tighten nut.

10. Install rotor.

11. Drop brake assembly back onto rotor and tighten two bolts on backside of carrier/ caliper assembly.

12. Plug in wheel speed sensor.

13. Re install wheel.

14. Raise vehicle, remove jack stand, and lower onto tire.

Hope this helps.

Hi, thanks for the pictures. Yes, the hub fell out when the carrier moved downward, and with no seal or bearing attached. When I removed the carrier, the seal inside fell out with the bearing, and the shim and spacer also. The shim was kind of glued with grease. The outer seal I had to pry out, and the other bearing I only just pulled out with my hand. Is this all a bad sign?

So, for new races, I just need to hammer in with a punch? Also, your pictures show the bearing on the hub, does it need to be done that way? It's a little different than Jaguar's instructions.

Hello,

The installation instructions I provided are a simplified version of Jaguar's instructions. Please follow what you are comfortable with.
A hammer with a decent drift/punch is all that would be required to remove/install the races. Just ensure that they are seated straight in the housing. I usually use the old race as a drift tool so that I do not apply direct force on the new part.

Good to know. Right now, I'm waiting for parts to be delivered. I attached a picture of one of the ABS rotors. Does this need replacement? It just looks bad. Also, I attach pictures of the other things just for this thread.

Hello,

The ABS rotors need to press on to the hub once the bearings are assembled.
It is important that the ABS rotor fits snug and is not loose. Same goes for the inner bearings, they need to fit snug.

There seems to be some wear grooves on the outer parts of the ABS rotor, unfortunately the pictures were not quite clear. I enlarged the one you had provided, see below.

Cheers, Boris

Could I use the same technique you mentioned above to press the rotors on to the hub? Like using a large socket or something to tap into place?

Hello,

Yes, you can.
