Hi Mathieu,
Thank you for your Email. It is not feasible to return to the servicing dealer (Kamloops Ford Lincoln) at this time as the truck is out of province and will not be back for a year. I use the truck for work and it stays in Alberta while I reside in BC. I had it to a dealer in Alberta (DK Ford) and had a very poor experience with them. The Kamloops dealer was outstanding, really good. The Alberta dealer was not. I will say that the staff at DK Ford were great, the service manager was great, but the service foreman or lead was NOT great at all and there was zero difference in the truck when I left.
The mileage is 68,500 km (+ or - 100 or so km) VIN 1FTFW1R65DF D06569, the vehicle is owned by my company 1866174 AB LTD. Please feel free to contact me if you need more info. It seems to me like there could be a machining error in the build of the slip yoke components. Simply greasing the slip yoke is a very temporary band-aid, not a fix.
