Hub Bearing Replacement - Success!


Recommended Posts

With my brother's help, I replaced the bad hub bearing this weekend. Total time - 2 hours, including new front brake pads. No major problems - followed the posted instructions and all went well. Ahhhhhhh....peace and quiet inside the Cad once again. It's like removing a splinter from your finger.

Here are some brief details/obsevations for the benefit of anyone getting ready to tackle this for the first time. Please keep in mind some of these things may be specific to a '91 Eldorado:

With my brother applying his full weight to a 2 ft. breaker bar, the hub nut wouldn't budge. Luckily, he has air and an impact wrench. Even then it took a while before it would loosen.

Note the exact orientation of the "front brace sheild" , draw a diagram if you have to. Otherwise, if you get it wrong, when you go to replace the caliper, you'll have to remove the hub nut and the torx bolts, like someone who shall remain nameless.

The hub nut is 36 MM on a '91 Eldo.

The caliper pins are not allen wrench, but standard hex head (at least on my car).

That's about it. All in all, a satisfying experience. (Plus, I got to hang out with my bro).

Please don't mistake any of the above comments as complaints against previous posters; I'm extremely grateful for all the advice and guidance I've received here. This is strictly FYI stuff, hopefully useful for the next guy.

If you are saying that I explained this as an easy job and it wasn't, its a crap shoot, sometimes its easy sometimes its not. My nuts came off easy but then I used an 18 inch breaker bar and a pipe plus I am 6'5" 230 pounds and bench 200 regularly so maybe that has something to do with it :lol: So it was easy for me...

Glad you are riding in silence again.....

Early on sailors navigated by the stars at night and the North star became the symbol for finding ones way home. Once you know where the Northstar is you can point your ship in the right direction to get home. So the star became a symbol for finding ones way home or more symbolically even finding ones path in life.

Mr. Scott,

No, don't misunderstand. The job went almost EXACTLY the way you described it. AND your diagram was helpful, too. Just got a little tense when my brother looked at me and said "This thing ain't comin' off.." and I suggested givin' another go with the impact wrench. Your directions were invaluable. There was another post in the archives where someone said air probably wouldn't be needed, and I'm just tyin' to give the next guy a heads up. You know, be prepared, and all that stuff.

While I'm here, I forgot to mention in the first post that my mysterious "whump-whump-whump" noise is now gone, as well as some slight front-end shimmy when braking, both probably attibutable to the bad hub bearing. No sir, Mr. Scott, I am one happy camper right now!
