Great parts, easy to install
I bought these front wheel bearings to attempt to remedy a horrible grinding noise my 2005 Mercury Mountaineer had developed. The video provided by 1Aauto was extremely beneficial and made the process smooth. My only issue was that I was expecting to see a center hub/axel nut and was shocked to see it missing. I did some research and figured out since this truck is NOT 4 wheel drive, I don't have that nut in the front. I bought a good torque wrench and followed the specs per the video. I did not have any trouble accessing the bolts since I could turn the wheels with the front of the vehicle on jack stands. I had never done any kind of brake work before, but after this, I certainly can since the brakes were removed to do this. Do yourself a favor and order a pair of the sway bar tie down bolts because the bushing probably need replacing. Easy to do since you will have the wheels off for the bearing replacement.Now the vehicle is silky smooth, however I am now hearing a little noise from my back right bearing which I may tackle next.

Very impressed
Although I had a miscommunication with one of the people I had sent an email to my parts came when they were supposed to. The parts I order I got for half the price all the parts stores near me quoted me for just 1. Thank you so much for the help and getting my order fixed in the timely manner. I will definitely order more parts from y'all.

Not happy
The sensors do not fit like the factory ones. So it is causing my awd, abs, and traction light to come on and stay on.

Do the new bearings come already pressed into the new hub assembly?
William H on Mar 10, 2016
BEST ANSWER: Yes all ready to go even comes with new hub bolts for the replacement
Does these fit the 2 wheel drive version of the mountaineer?
Curtis C on Mar 13, 2016
BEST ANSWER: I used these hubs on a 2005 Lincoln Aviator and they worked fine with no issues. I suggest you cross reference the Ford part number to the 1A1 listed replacement part numbers to make sure you order the right part. You can go to a Ford parts website and get the hub part # then cross reference it to 1A1. Good luck , either go on line for a video on how to remove the hub assemblies, look at a few they are very helpful, plus make sure you have the right tools for removal and installation.
Is grease already applied to the bearings?
D.J. B on Jun 23, 2018
BEST ANSWER: These are sealed hubs. The bearings are press fit. And do not require grease. A small amount of grease should be applied to the axle shaft for easier fit up though.
Is the driver and passenger side the same? Or do I need to buy different ones
Greg B on Mar 27, 2017
BEST ANSWER: They are both the same. You don't need different ones. I used them for a Ford Explorer 2002 RWD, when my driver side bearing was making aloud noise on the Freeway. I decided to change both at the same time as old ones were the original factory ones.
