    I have a whiny rear diff and I think I’m just going to swap out the rear end with a used one from eBay. The problem I’m running into is finding one that fits my X.

    Its a 2007 Manual Transmission, 4x4 and not the OR model. The rear diff is the 3.54 ratio M226 based on what I’ve found.

    There are not a lot on the market right now but I have found a few reasonably priced rear ends with the 3.54 ratio but they have come off of 4x2 not 4x4 like I have. This might be a dumb question but I can’t find the answer anywhere. Will the 4x2 work or should I keep looking?

    As long as the gearing matches you'll be fine. They're identical.

    Yup. You'll be fine. I think 3.54 was manual trans only, so any you find should be the M226 and not the ck100

    That’s what I’m thinking as well but I don’t want to do all the work and have something not fit correctly

    Great! This is good news! I’ll probably buy one soon and bolt it on

    I just spoke to someone who said the pinion flange may be different on the 4x2 (4 bolt vs 6 bolt) so I’m trying to find some more info on that.

    Gearing matches but someone mentioned the pinion flange may be different (4 bolt/6 bolt) between the models so I’m trying to figure out if this is true

    Yeah. Some further research shows that 2wd might be 4 bolt. You can buy a different pinion flange, but that's extra work

    Here's the 6 bolt flange from Rugged Rocks. Just in case you decide you need it

    That’s what I’m seeing as well. I’m going to look into if the 6 bolt will simply bolt on or if there are any other issues I may run into. Thanks for the help!

    Should be able to swap your current flange on the new axle.
