I never removed the iner dust cover.I used the iner dust cover two pry against with two screwdrivers in order to remove iner race.it isnt on tight. I didnt have locking pullers.I didnt have a hub tool so I used the 6 point 46mm socket to tap the hub on.If you dont have the tools this works.

Again, I can't stress this enough.. The reason why you should use the bearing-installer during initial hub mounting is to prevent any uneven strike-forces that may knock out the bearings and/or bearing race. You should also use the 36mm socket to help fully set the hub so to prevent accidentally hitting the hub for the same reasons. Yes, you got your hub onto the axle using your method, however the risk is too great that you also have damaged your new bearins doing it this way.. IMO

If my videos helped you replaced your hub bearing on your BMW, rate Thumbs Up. Thanks.

And, you got to admit > having some music and Hi-Res photos Beats just reading an old Repair manual and going by some line-art illustrations any day.

Bearing installer kits can be rented at some auto parts outlets. Check your local stores.

@02325ibmw

I gave an explanation in the video...The reason is explained around 3:30 in. DO NOT use the 46mm socket, you Risk striking the hub with it. You can damage/knock-out the (outer most) race, thus ruining your new hub.

[02325ibmw]

@bimmersgarage Why cant you use the 46mm socket to tap the hub back on? I thougt that would work . hope hear back before I use it.

Take the cap off and visually inspect. Take some pictures (or vid). The main thing is there shouldn't be any grease,oil,etc coming (oozing) out from between the inner hub and inner race - the bearing seal is directly behind that. Also, you can check my other video on what a bad hub bearing sounds like when you have the caliper removed and you give it a spin. But, at 103K... it's past time to replace anyways. Just so you know.

[dpersh76]

@bimmersgarage 103K, it's 2003 325i. I suspect I will need to look check what's going on under that dust cap soon...

[bimmersgarage]

@dpersh76

Thanks.

So, how many miles are on your E46? Is it an Xi? And, just so you know, there should NOT be any fluids/oil coming out from the "front" dust cap. If there is usually it's a sign of a failed bearing seal...

[dpersh76]

Great DIY instructions, thx! A question for you, though. I was doing break service on my e46 the other day when I found one rotor seized to the hub really bad. Long story short I mistakenly pealed the edge of the front dust cap off of the hub... I quickly realized that I'm doing something wrong as I saw a small quantity of machine oil come out around the edge of the front dust cap. I forged it back on to seal as well as I could and observed no further leakage. Should I worry hub will fail soon?

[DesertWetBalls]

Aww the brake shield does not come off if the inner seal behind the race is still on.

@DesertWetBalls

You're welcome. Good to hear that my vid was able to help you out. Be careful when you install the hub... use a bearing installer tool/kit to avoid damaging the bearing. Just make sure you torque it down to spec for your vehicle. And, remember to notch that axle nut (for safety) after you have the hub bearing installed. Good luck.
