So..another diff thread. 1st time I have had front diff issues...Here is what I have going on. Changed fluid a month ago and checked it again today..still full (yes correct fluid used). I was out plowing and when I back up the 4 wheel drive works but going forward it does not...After sitting there for a while backing up, i manged to get the front to lock back in again and it seemed to be fine down the road. I noticed this problem last time I was plowing but it seemed to come around after the first time I switched off the AWD and shut it down (it was also -40 out) so I thought she was just flat out cold. Any ideas? Checked fluid level, fine....checked omhs @ the harness and they are within the range the book states..could this be a warped armature plate? Like I said...works every time in reverse...just hit and miss all of a sudden going forward...

 

Old Polaris Tech...what do you think? Armature plate or going bad roller cage?

 

If your going in there replace the armature plate and check cage for cracks and wear. OPT

 

Does anyone know the part numbers for the John Deere parts? Would rather replace with metal then plastic...Thanks

 

John deer parts are- Roller Kit #MIA10666
Cage Kit #MIA10667
Seal Kit #MIA10654

 

i have an 05 sportsman 400 are the parts the same to fix my front diff awd problems

 

Yes , anything with the newer front diff instead of hubs, dont know about the 550 and 850 , they might be different.
