OK, so I just drove a '99 with 72k miles on it. Overall it seemed to be in pretty good shape. I do have some questions that I could use a little help with.

1. Axle code was B6. I believe this is 3.73LS Right??
2. Tranny was E. This is either E4OD or 4R100, but I'm not sure which. Can it be either?? I was thinking the E4OD went away before '99 but...
3. The truck is an x-cab and the rear doors squeak a bit when you close them and the main doors. It also does it over some bumps. Is this normal and is there a fix??
4. How do I tell if it has the PI heads?? In doing a search it sounds like some of the '99 250LDs may have got the older heads. Is that true and how can I check? Or all the non-SD truck 5.4s PI equipped??
5. What wheels are available for these 7lug trucks?? I did a google search earlier and found NOTHING. Even the tirerack.com and discounttire.com had no offerings. Bummer...

Otherwise, the truck drove tight and seemed to be in pretty good shape. Carfax is good.

Thanks for any help!!

 

Question 1&2: Check here to get the codes from the door sticker:

Question 3: The door strikers on the cab can be adjusted to tighten up the doors, if this is what is causing the squeaks.

Question 4: The heads should be stamped PI, if they are PI heads but not sure exactly where they are stamped.

Question 5: You will be limited to wheels but I think they are out there.

 

Right, I looked at the code thing. It goes all the way back to like '91, so that is the source of my confusion.

As for the doors, is there a latch at the top and the bottom of the rear doors?? I noticed one at the top of the cab, but I wasn't really paying that much attention. If there was just one at the top, that would kind of explain the added motion and squeaking.

 

There is a door striker at the top and bottom, the bolts can be loosed and then take a scrap piece of 2x4 and tap it with a hammer to slide the strikers back just a bit and that should tighten up the doors.
A 99 250LD should have the 4r100, just a newer version of the e4od

 

OK, so I looked in the FAQ at the top of the page and found that there is a link to Eagle wheels there. They sell one wheel I guess. Not really my style.

At this point, my only question remaining is how or rather where do you look to find the PI on the heads??

 

I'm going from memory here...but I believe you can see it on the driver's side, just below the valve cover, about the middle of the head. You may be able to see it on the passenger side as well. If you want, I can take a picture of it on my 99 f150 5.4 when it stops raining. I belive the F250LD's were all non-PI 5.4's.
My owner's manual says all 250's w/5.4 and automatic transmission are 235hp@4400rpm.

 

If you can just tell me where on the head it is approximately, that would be awesome. I found a pic on this site, but it was pretty close up, so I couldn't really tell where it was. It was above and between 2 exhaust ports, but that was about all I could tell.

Also, here is another question- what does the manual say the towing capacity is for this truck with 5.4 and 3.73 and it is a 4WD x-cab.

 

Damn. It already sold. Guess I should have moved faster.
