    Yeah, that looks like the one Dan used. There several available. There all the same dimensions, tho I'm sure there is a quality difference.

    Here is the one I ordered:
    $8 6301DU Sealed Ball Bearing 12x37x12
    https://www.amazon.com/dp/B010OLLHM...olid=1P5D39KHH5V3M&psc=0&ref_=lv_ov_lig_dp_it

    FWIW, I ran quite a ways with mine noisy AF. I was too hot to touch when we finally did the swap with the pulley from O'Rielly's but it never caught on fire or froze up or made the belt jump off.

    We had a skunk take a liking to Monte's truck bed one evening in camp. Little fucker would not leave. They finally gave up trying to shoosh it away and went to bed in the RTT directly above where the little guy was hanging out. He was gone in the morning. YMMV

    Thanks man!
    Yeah I could always pull the belt. But it'd be nice to have an order in and a delivery outgoing before I leave pavement.

    This little guy is at my feet everytime I sit down. Probably being fed.

    Thanks again Mike!

    Yep, you can order that one Mike mentioned, or the one I got, which is the first one you linked. I've since had mine pressed into the OEM pulley and it worked great.

    How much effort does it take to press in? I was under the impression a c-clip was used to secure it, no?

    C-lips secures it. It doesn't much to knock them out. Just a socket that will catch the outer race and a hammer.

    You might try loosening the tension a little for less stress on the bearing.

    I purchased the whole AC idler pulley for under $40. ac idler pulley 88440-04040 - there’s the OEM part number. Gunny can get you a good deal on one. Let me know if you need more info. Good luck!

    I heated up the pulley to where it was uncomfortable to touch bare handed, and put the bearing in the freezer. Dropped right in.

    Question, are you guys getting a loud howl noise from the AC compressed when it's on? Is the new bearing supposed to fix it or is my AC compressor going to take a dump? I can tell the howl is much louder when the compressor kicks on.

    Idler pulley is always turning with the engine.

    I see. So it's safe to say it's my compressor

    Just went through this two weeks ago. My compressor was in the process of taking a dump. After the replacement the idler pulley (bearing) really shit the bed. Bearing cage came out in chunks. I had the part number for an NGK bearing but the dealer had a whole pulley available that day. I was in a pinch so I bought the whole assembly. As for bearing replacement it’s super easy with no press or heating. Just do it carefully with a socket.

    It’s an NSK bearing 12mm shaft dia 12mm thickness and 37 mm OD.

    Edit: it’s an NSK 63012RS-DDU bearing

    So you replaced your AC compressor but not the pulley? I'm currently in the opposite situation.. been pulley but the compressor is still really loud

    Compressor was replaced, then the pulley seized and belt snapped. Replaced entire pulley. Now all is well.
