Mountaineer hub assembly
Perfect fit and thanks to your excellent video, a very doable project. One suggestion for the video, the old hubs do not come off with a rap on the hubs. This was the most time consuming part of the project. Keep up the great work, in my book you can be proud of the job you are doing. Bob Stordahl

Again i ordered from 1A Auto and again i received amazing customer service with my questions , talked to someone that spoke english and was able to understand and was very helpful. Although I didnt put the parts on myself this time, i had a mechanic, the mechanic asked where I got my parts and I told him 1A Auto , I told him that you are my #1 parts supplier now. Thank you for everything you do. I love the videos.
Keep it up.

Great buy!
Price was about 1/3 for similar parts quoted by retail auto parts stores. Very prompt service. Was out of stock when I first looked but got a quick email within a week to notify me it was back. Free shipping as well!

is this part made in america?

Do the new bearings come already pressed into the new hub assembly?
William H on Mar 10, 2016

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 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.
How long till I get it?
