    Default Maybe Mopar is right!

    They say to change the ACR hub and bearing every 12 competition hours. Mine busted at 19 hours. Luckily, I decided to take it apart and see why the axle nut had slacked off twice, so no harm done. It broke right at the outside edge of the bearing, so the spline of the outer joint was doing all the support for the wheel. I wonder how long the axle would last before the wheel/brake assembly exited the car in a spectacular fashion?

    The acr hubs I just changed out had over 25 hours of w2w track time. Thing alot of it has to do with what type of tracks you run and car setup.

    Default Hub failure

    I experience a hub failure this year at Sebring and my hubs only had approximately 10 hours on them, when it failed it snapped the axle and luckly the wheel did not exit the car before I got it stopped. After being put on a flat bed and brought back into the pits upon jacking the car the whole wheel assembly fell off. What Chris Childs told me was to check the torque on your hubs every session for two or three times and them make it pre race weekend check. The hub tends to back off and allows to much slack. But yes you need to change these every 12 hours of track time to be safe.

    The ACR hubs are on national backorder up here- there was 7 on b.o. this morning when I phoned my dealership, now there is 11, since I run a Neon ministock too. If they don't show in a couple of weeks I may have to start beating the bushes for a source. Any suggestions?
