I replaced my first set @ 65K. I had 35inch tires & wheeled it moderatly hard. Just put in a new set when I swapped out my axle @ 105K miles with 37inch tires from 75k miles & they seemed to be pretty worn out.
It is different and it will work but you do need to route the speed sensor line behind the shock like you would on a 2007-11 and NOT mount it to the bottom of the shock mount as is what you would do on a factory height 2012-up.

Thank you for a great post. I swapped out my passenger front today. I would have had to fork over more than I could afford to fix mine.
This was the biggest repair I have done to date.
I owe you a bottle of honey. Note the SAMs was a rainy day work buddy.

And here I was using anti seize instead of lock tite when I had a hell of a time tearing all that down to do axle shafts. Now I have to go back in for a bearing. Glad I did that now!

Were you getting a wobble?

Yes, slight, but it's making a clicking noise when spinning. :banghead:

Amazon - "Does Not Fit Your 2014 Jeep Rubicon"
I went to Amazon with the part number from the write-up - HA590242. Amazon does sell this unit bearing but states that it will not fit my 2014 JKUR. I've searched a lot of places and have yet to find a site that sells a unit bearing that specifically will fit my Jeep. At least one write-up gave me the impression that something changed around 2010 to 2012 but there was nothing that said what the change is. From one of the Wayalife responses in this thread, I got the impression that the only difference of significance was the length of the speed sensor wire bundle. I don't need one at the moment but from comments on this thread, it seems that they go out fairly frequently and it would be good to have a spare on hand.
Thanks
Edit - finally deciphered the Timken catalog - the number for 2012-2016 appears to be HA590482. The cheapest I've found so far is Rock Auto at $101.79

Just changed the bearings on my jku. Thanks for the great write up. Having just changed my ball joints this was a piece of cake.
I used the autozone duralast unit bearings which I discovered are made for them by timkin.
Question for you guys about the new speed sensor wire being shorter and having to re-route it. I was curious if anybody's tried to use the factory sensor wire on the new bearings. I used the new ones, but saved the oe's just in case.
Yup, you can definitely reuse the factory speed sensor wires if they're still working.

When routing the new, shorter, abs line did you route it with the brake line or is it ran separately?
