    2006 Grand Marquis Bearing Hub Sleeve???

    I have a 2006 Grand Marquis. My driver side front hub started making noise so I went to replace it with a Motorcraft NHUB63 I bought on RockAuto.

    The original hub was very tight inside the steering knuckle but I got it out.
    The new one went in easily and didn't fit tight inside the knuckle at all. The knuckle opening seems too big to accept the hub with a tight fit. There was way more play that I was comfortable with.

    Turns out the original hub had a spacer / sleeve that fit over the part of the hub that inserts into the knuckle to make it fit tight.
    I had to jimmy the spacer off the old hub and put it onto the new one, and it fits nice and tight like the old one.

    I can't find this sleeve anywhere though and there doesn't appear to be a part number for it. What do mechanics typically do? Do they move the sleeve from the old hub to the new one, or just install the new hub without it and rely on the 4 bolts to hold it tight?

    They do exactly as you did. Then throw some lok-tite on the hub bolts, torque it and call it good.
    These are highly engineered precision vehicles, the first step in diagnosing the problem is to strike the suspected offending part sharply and repeatedly with a blunt object, then re-test.

      I agree with FordMan77. I had to laugh at the question because HERE they would just let 4 bolts hold it on. "Good enough until the car is junked" Very few "mechanics" here do a proper repair, or care.

        Re-use the old sleeve. Just like you did. At least good mechanics. Bad ones would just bolt it in and hope for the best.

          Without the sleeve or matching diameters so it pilots in there, its going to be much weaker. The 4 little bolts just are not strong enough to handle the load of an entire car in shear. I'm sure people do just run them in with bolts but that is absolutely not the right way to do it.

            If it's needed, why can't you buy the sleeve?
            I asked the question here because while it seemed the like the right way to do it to me (the move the sleeve to the new hub), it wasn't obvious at all that there was even a sleeve on the old hub. I only went looking for it because the new hub just didn't fit right.

            So I gotta wonder why a new hub doesn't come with the sleeve, or atleast the sleeve should be available to buy separately. I can't find it anywhere. I checked multiple videos on how to do the job and nobody mentioned the sleeve at all. So it makes me wonder if something is different about my car (maybe at some point the knuckles and hubs were changed to ones that aren't really the right ones for my car).

              Have you checked with the Ford dealer ? They will need your vin number.

                I've never done a hub bearing on one of these so I don't know. I can just tell you that if it slops around in the hole, something isn't right. Every hub bearing I've ever done has been a tight enough fit that it requires a wire brush and scotchbrite to get the hole in the spindle clear enough to allow the thing to fit in properly.

                  Just went through the same thing on my 2010 TC. The Autozone bearing doesn't come with the sleeve either. The sleeve on the old bearing was too far gone to use. (14 yrs/465,xxx miles) You can get them new with the sleeves, you just have to check before you order them. I ordered new ones from Rockauto, and made sure they had the sleeves. The sleeves are NOT available from the dealer. They are not even listed as a separate part. I am also replacing the steering knuckles at the same time. For those wondering, the Motor craft numbers for the knuckles are MEF74, and MEF75. They are literally 1/2 the price of aftermarkets. The best deal you are going to get on them is from Rockauto.
