Rear differential leaking, but not from seal on 2003 ford f150 aluminum driveshaft?

I noticed this yesterday, it's barely leaking, however, it's not leaking from the bottom of the seal, it is leaking from where the back face of the u joint(the face that faces the rear diff) and the pinion and it looks like it's coming from a small hole, I don't know why it is leaking fluid, if anyone has any information, that would be nice, thanks

What's wrong with my truck? - 4

I have a ford F-150 2004 lariat 5.4l triton v8, so in the morning it was running like always but then in the after noon around 4pm i took it out to my dads ranch and as soon as i drove on the dirt and bumpy road it said low oil pressure and when i parked it it said check engine and started shaking like crazy. So then i turned it back on and when i put it on revers it shook again and said check engine so the whole 30 minutes trip home it was ok until i got to my driveway i put it on revers and it shuts off about 10 second later. So then i took it out to the corner store and the oil pressure said ok check engine like was off and it hasn't turned off or hadnt shooken what should i do i'm kindof worried i take it to work Far everday and i don't want to get stranded.

1988 Ford F150 starting problems?

I came outside a week ago and it wouldn't start. Something is draining a lot of power I know. Sometimes it will buzz when I try to start it and other times it won't do anything. Since first discovering I have done the following. Replaced the starter, replaced battery and both battery cables. A little bit ago I ran the negative cable directly to the starter hoping to get a better ground and still not working. Any ideas?

Need some vehicle advice please?

So I bought a 95 ford f150 a while back and now have an offer to trade it for a 94 dodge 2500 single cab they have the same amount of miles "215000" mine is a automatic the other is a standard 5 speed… The ford has the 5.8 v8 the dodge has the 5.9 v8. I was wondering if there are anything I need to look for on the dodge like if dodge has certain bad transmissions i need to look for or anything like that… Also I would like to put a cummins in it and would like a estimate on how much it would cost to swap the engines… Is it even worth it? The dodge looks nicer then my ford but the ford runs great. Not sure about how the dodge runs yet but will know soon. Any recommendations or help would be greatly appreciated
