proplem with my front end

[BigGreenBronco]

MY bronco makes a very high pitched whining noise whenever i start moving forward and its coming from the wheels i dont have a clue what it could be its seems to only make the noise when i am moving at a low speed do yall have any ideas?

Yes. Odds are you fall into the same catagory as me. Mid 95 they switched to 2 piece grease seals for the front bearings. If you pull the squeeling side apart, there is a seal that sits on the hub, Odds are it is working it's way out. At one point I had taken it apart, tapped it back in and it was fine for a month. Ended up replacing them both completely, and its been fine ever since.

(BTW, the parts houses round here didn't list the 2 piece on the Bronco, only the F-150. They kept sending me the old style, that will not fit.)

is it dangerous to pull apart those auto locking hubs( thats what i have) is the seal on the inside or do you get to it from the outside of the wheel

Its the inner seal that creats the noise. Its ptrtty easy to pull apart the auto hubs. unbolt and remove the cover, then grab a rag to clean out the grease. This will make it easier to see the snap-ring holding in the auto lock. remove that, pull out the hub, and then the bearing nuts and so forth. Fairly simple task, just a lil messy with the grease an all. (PS, there is a special socket required to remove the lock nuts holding the bearings. If not avail, can sometimes be CAREFULLY done with a screwdriver.)
