    • Q: Threaded end sticks out from hub further then oem  adventures911 year ago

      Just got these installed and the threads stick out quite a bit further out then stock. This makes it so the nut cannot be dimpled and locked in place as it threads on much farther. I have done a bit of research and seems to be common issue. Just wondering if there is a recommendation for what to do to make sure the nut doesn't spin itself loose.

        A:  Yep, I've heard of that too. Most people I know will just use a bit of thread sealant on there, i would probably go blue personally. If you really wanted to double up on the safety you could drill a small amount where the nut could be tapped into the shaft, or you could drill all the way though just to the outside of where the nut stops and throw a cotter pi through it, or even drill through the nut and shaft and secure it like a tie rod or ball joint, "castle nut" style. in all reality with proper torque, I doubt the nut would ever back off, but the ideas listed above would certainly make it so it would not. :)

    • Q: Front Axle shafts  Beekeeper FXT1 year ago

      I have a 2004 FXT and wanted to see if you guys offer any direct fit replacement front axles that before I order OEM. Thanks.

        A:  We do not carry any for your vehicle unfortunately. OEM would be the alternative route.
