Hi i have a 2007 f150 fx4 just wondering how hard it is to replace the diff clutches? i have had the truck for about 3 years now i believe and every year pretty much to the date the diff clutches last year my warranty expired so i guess im on my own now... so i wondering if anyone here has ever done them or if there is anything i should know going in or if there are some after market clutches that are better than the ford ones because to me it seems that the ford ones are really not that great since in my case they only lasted a year every time which i find ridiculous.
Thanks for the help
