    Bad luck or does my car really destroy hubs and speed sensors?

    I'm now going on my forth hub in less than 2 years. I replaced the first one about 18-20 months ago because it was loose. Then about 12 months later the speed sensor was working sporadic and throwing codes so I replaced the hub again. Then about 500 miles later the speed sensor stopped working in that one and putting out the same codes. So about 5 weeks ago I replaced the hub again with a Timkin since I had been using Carquest. Now after about a month and 5kmi later the abs light came on and not more then a day later the hub started howling. I jacked up the car and sure enough its loose. Sometimes I can drive the car 50 miles and the light won't come on, or I can drive it 6 inches and it comes on. I don't think I'm installing it wrong since there appears to be only one way to put it in. So now a new Timkin should be here tomorrow, but do you think I've had bad luck with defective parts, is it the terrible roads here or something else?

    Timken usually don't fail anywhere near as often as whitebox. It's common for whitebox brands to last six months to a year.

    4 hubs in 2 years points to other problems, though I'm not sure what.

    Oversized rims?
    Extremely bad roads?
    Dead strut that causes the wheel to hop constantly on the highway?
    Bad shimmy?

    Stock rims with OEM size tires. I do noticed the car does vibrate quite a bit between 70-80. But the tires have been balanced multiple times and they balance true on the machine after weights. I was thinking of going somewhere different to see if a different tire balancer makes a difference. I do drive on some pretty bad roads between Providence/ Boston and Maine. I don't think the strut is bad, the car handles well, but I'm not sure how I would more scientifically test it.

    We probably drive on some of the same bad roads. I'm in Chelsea quite a lot too, and those roads are just ridiculous.

    Check for and clean any corrosion from the rim/rotor/hub mating surfaces. If there's still a shimmy, have the tires road force balanced. You might also want to check the front motor mount.

    What tire pressure are you running?

    I'll clean the surfaces up when I put the new hub on, but from what I remember they weren't bad. I was also thinking of road force balancing when I get an alignment. The tires wear evenly, but my steering wheel is off center and that bothers me when I have to stare at it at least 2 hours a day. I believe I'm at 35psi, but I didn't check when I go my snow tires taken off.

    Just throughing this out there, are you torquing it properly. Check the routing on the wire from the hub, I had one rub through on the axle shaft.

    35 PSI won't cause hub issues, but I believe the label on your door says 30 PSI. You'd have a softer ride.

    Re: Bad luck or does my car really destroy hubs and speed sensors?

    So when I was taking off the old hub, it looked nothing like the one I put on that was supposed to be a Timkin. The new one actually says Timkin on the front where as the old one does not. I'm wondering if the wrong hub ended up in a Timkin box at rockauto?20140510_090827.jpg

    The part number that I find on it is PBR930548K which when I google it comes up as a Napa wheel bearing. WTF?

    Could be a whitebox for napa made by timkin or a straight up wrongly boxed unit, it does look different...
    Can't remember If the last Timkin I installed had studs like that new one but I think not.

    Are you saying what I think is true? I got the wrong hub for my car and now the one I have is the one that
    s made for my model car?

    BTW the guy that swapped my snow tires to all seasons, put 40 psi in the tires. I deflated it to about 34 psi in each tire.
