    • While on the topic of front bearings, and potential knuckle worn what knuckles interchange with the 450? @jeepwm69 I think may know?
    • This might be helpful info at some point:  
    • Welcome Hemi21712! Let us know if a Genuine Honda angle sensor does not fix it.
    • Hi mquattlebaum, welcome to ATV Honda!   DTC 6 generally indicates one of three possibilities. Either the battery voltage supplying the shift ECU is low, there is a poor ground somewhere, or the ECU have failed. Running the ATV without a battery in it or running with a bad battery in it can cause a code 6 and/or cause the ECU to fry. So first make sure that the battery is in good condition and is fully charged. Make sure that the regulator/rectifier is charging the battery at the proper voltage too. Also poor/dirty/corroded/wet electrical connectors can lead to ECU problems, as can a chewed up or hacked up/spliced wiring harness or high friction/drag in mechanical electric shift components. Refer to the factory service manual for the charging system output spec, linked on our site from here.   If the battery is in good condition and fully charged, begin by taking both fenders off, disconnect every electrical connector on the ATV and clean the contacts with an electrical contact cleaning spray. Look closely for corrosion inside connectors as you work. After cleaning each connector pair apply dielectric grease generously inside them before snapping them back together. Remove the negative battery cable ground bolts from the motor case and the frame and shine those connections up too. All grounds must be clean and tight. Dielectric grease them to prevent them from corroding.   You will need to insure that every electrical part is a Genuine Honda part as well. If you have any china knockoffs on your Foreman you'll never fix it.   Let us know what you find... here is a guide for ES system prep you should follow after the code 6 issue is fixed.    
    • You'll have to fix that speed sensor issue to get it to shift. The first step though, before any further diagnosis or work, should be unplugging every electrical connector on the ATV, cleaning them with electrical/contacts spray and dielectric greasing every one generously before snapping them back together. You'll have to take both fenders off in order to access them all. Be careful with the ECM connector while unplugging it and plugging it back in (don't bend any pins on the ECM), but do not skip cleaning the pins & connector sockets and dielectric greasing. Odds are that dielectric greasing of every connector will fix the speed sensor and possibly the angle sensor issue too.   Next thing I gotta warn about before diagnosis is that all electrical parts must be Genuine Honda parts. If you have any china knockoffs on your Rubicon you'll have to replace them with OEM parts, else you'll never fix anything. So if your new Angle sensor is not a Genuine Honda part then take it off and throw it in the garbage. Put the OEM angle sensor back on it (with connector dielectric greased) for the initialization and diagnosis steps.   Once ya got every electrical connector prepared and have OEM Honda parts on it you'll need to initialize the system. Follow the initialization guide below exactly, the list of DTCs are included for reference. Let us know if there are any issues remaining after....
