i have a 1996 ford f-150 4 wheel drive automatic ! it has those automatic hubs and they are acting up ! i am thinking about changing them over to manual hubs ! i can get a set of warn hubs at advance for $125.00 ! the person in there said all her husband did was took out the automatic hubs and put in the manual hubs on her explorer ! are they that easy to change over ? i never owned a 4 wheel drive before ! everyone i talked to said you don,t bother the transfer case at all, just take the automatic hubs out and put the manual hubs in ! is all the work at is at the wheels ? thanks guys ! have a nice day !
