Preventive/Preemptive Tasks

sure this has been covered ad nauseum but here goes:
2002 F250 7.3, 129,000 miles, rebuilt tranny 4R100 w/ 2648PS Torque Conv.'08, cam position sensor, 2005 (+,-), Rear Axle Pinion Seal 2008, rebuilt rear end 2010. Upper/lower ball joints will be coming up, had minor slack in 08/2012.

Mainly want to preserve this incredible engine and not be stranded with my 5th wheel in the middle of nowhere. This truck is 70% pulling this trailer and 30% ordinary driving.
Any advice or warnings of things I could preemptively do.
Thanks for all the great info found at this site.

High pressure hose on the power steering pump reservoir. They are known to blow out of the reservoir at the swivel fitting. Change the hose.

Oil hoses from the HPOP to each head. There's an updated design and the old ones are old and have been known to blow out. Change them.

Check the fuel line going from the filter to the back of the passenger side head for signs of chaffing or wear at the clamp that holds it in place near the back of the motor. If it looks worn, change it.

If you haven't done the in tank mods, consider them since the in tank screens haven't ever been cleaned.

Wow, as I'm not a gear head this is stuff I would have never known about until....
Thanks very much!

what about sensors considering the age, or is it more about mileage and/or service conditions.

Leave a CPS is you glove box with a 10mm socket with a 3 inch extention. You never know when it will go, but a 10 year old sensor is probably on it's way out. It's worth $27 to not have to pay for a tow. BUY FORD OEM, aftermarkets are known to be shotty. I suppose you could do your ipr.... but probably is not necessary until you start to show symptoms. GP relays go out often enough, but another item you should probably wait to do until it shows symptoms.
When it comes to electrical on these trucks, it's just like the old statement "don't fix it if it ain't broke"

I was about to post what F350-6 said, but he nailed it before I could type. There are always more things you can do, but sometimes one can get carried away and put too much effort/cost into maintenance. I feel F350-6's list is spot-on for those miles, and if this were me - I would want to gauge up to keep an eye on things as the truck ages. I should point out that I'm a freak about being in-the-know, so others may feel differently. However... since you already lost a transmission, one might ask if knowing the transmission temp might have helped before the need for a rebuild. This option would also answer your sensor question.

Thanks guys for the responses.
Tugly, the factory transmission gauge never showed high temps. It just started slipping when in reverse. It was still a young truck at that point.

The factory trans gauge is notorious for showing happy temps when in fact the trans is cooking. If that gauge shows hot, it's too late. If towing you need either a real aftermarket gauge or monitor the temp via OBD port. Either method will give you accurate readings. A trans cooler from a 6.0 to replace the OE is also a wise investment.

Google up Failure Prevention Thread, lots of good reading there.

Agreed with everything above too.
