I thought I would also post this in my "new member" thread as it is my first question for the forum. If anyone can point me in the right direction, it would be greatly appreciated!
New 2012 JUKR - was told I was getting 4.10's, really got 3.73!
Just purchased 2012 JKU Rubicon (my first jeep EVER). One technical requirement I was adamant about getting was the 4.10 axle gear ratio. Going into the dealer I thought Rubi's came with 4.10 standard. At the time of purchase, the dealer of course confidently confirmed that the 2012 Rubicon w/5-spd auto I was about to sign papers on indeed had 4.10's. So, we made the deal, and I drove my new Jeep home.
4.10's standard in all 2012 Rubicons?? Not true as all of you know, and now so do I. The MANUAL 6-Spd transmission comes standard with 4.10's. The auto comes with 3.73 as standard equipment.
For the record, I have returned to the dealer and they verbally have been cooperative, saying that "we'll get it fixed right", acknowledging they thought they sold me what I wanted - a JUKR with 5-spd auto and 4.10's.
My SPECIFIC question is this: What OEM parts (complete BOM) will I need to change from the 3.73 to the 4.10's, and what will be required labor-wise? I intend to have the work performed at the dealer using OEM parts and getting any warranty info in writing. I just want to keep an eye on what they do.
Note: I do not want repeat the various arguments of 3.73 vs 4.1 (or vs 4.56 or any other blah blah regarding ratio for that matter), dispute gas mileage vs performance, etc. Nor do I care who thinks who is arrogant or ignorant - such an exchange is a complete waste of time. I just want an accurate, technical answer!
If it is already in this thread, or even this forum, my apologies - I am weary of reading thread after thread and sorting through a lot of filler to find answers.
