Have you checked your front hubs. Pull them apart a d give them a good clean up and service.
Are they vacuum activated or mechanical?
If they are vaccum check for any leaks.
Easiest optio is to fit freewheeling hubs ? I think that will solve your issues. Factory hubs have been know n to be problematic.
