    while It sucks, good to hear I'm not the only one.

    I tried Timken same result. I also read an article that Timken has 2 models of hubs and one is stronger than the other...have not been able to confirm

    The 37's may be the issue. It happened with the KO2 but now more frequent with the wider Coopers.

    Time for 35's and new wheels! lol

    My dash ABS, EPS lit up on my way back from New Mexico @80-85mph- thought it might be clock-spring since cruise control stopped working.

    Once I got home I was back on freeway again the following day @65-70mph

    I felt a slight wobble on my way home and when I made the turn onto my street I heard the scraping sound.

    Jacked it up and the passenger side was so loose it took no effort to move the wheel with one hand...like a very loose tooth

    Axle is PR44, I don't think it's bent. I think I would have other issues if it were?

    Dynatrac ProSteer ball joints.

    Rancho knuckles.

    Luckily the hubs have been replaced under warranty but it's too suspicious that it's only the passenger side and at about every 6 months.

    I feel incredibly lucky that I didn't loose that wheel considering the speeds I was traveling at.
    How many miles are you putting on it in 6 months ? I have the same setup and about to get 37s. Guess I need to keep a spare handy just in case.

I was replacing them with timken unit bearings, the one that failed was a timken.

    I just don’t think the unit bearings can handle the 37s. I was also running a PR44/ProSteers/highsteer knuckles.
    Did you pull the seal off to expose the bearings for the photo?

    I always carry a spare and tools to change it. I’ve had some last for years and others less than a month. Interesting idea on the hubs though. My wheels and rotors are already dual drilled for 5 on 5.5 so might be worth trying out. Hmmm.

    The problem is that you're running wheels with too little back spacing. Factory is 6.25" and anything less than this will put a LOT more strain on your bearings and ball joints. Being that you're running ProSteers, they should be able to handle the stress better but if you're running wheels with 4" or even 3.5" of back spacing like most guys like to run, replacing your unit bearings is something you'll have to get used to. This is a BIG part of why we wanted to go wide on Rubicat. By running 72.5" Dynatrac axles, we were able to run wheels with 5.5" of back spacing and in addition to protecting our ball joints and keeping our bearings lasting a long time, steering was greatly improved and we also got a much better turning radius out of it too.

    So you're gonna have the same problem with those Spyntech hubs, although they may be a little stronger than the stock unit bearings.

    And for $1400 I can replace the unit bearings for a long time. Especially if they are under warranty for the part. Lol!
