brother bought a 1999 F250 last year. hasn't used it much, but is replacing his dodge v10. pulls a 28ft 5er last trip out, said he has a lot of porposing??? he thinks he needs new shocks. ...
If he doesn't know the history of the truck, I would do all fluids and filters. Then he knows it is all fresh and ready. Then start tracking miles from there.
There are a lot of websites for info. Ford Truck Enthusiasts is one I use.
Dieing when pull up to a stop, possible torque converter not unlocking.
