I was just wanting to know what all the differance's are. I know dif turbo, dif breaks and bolt pattern. and help would be great.
Thanks Travis

 

Early 99 has a wicked wheel in it from the factory.

The early99 has 120cc(AB code) injectors and the late99-03 has 140cc(AD code) injectors.

The early99 has 2" intake runners. The late99-03 has 3" intake runners.

The early99 has a 15* swash plate HPOP. The late99-03 has a 17* swash plate HPOP.

The early99 has one glow plug relay. The late99-03 has one glow plug relay and one air intake heater relay side by side. Both relays are on the passenger side valve cover toward the front of the truck.

The early99 has a totally different air filter that is not inter changeable with the late99-03. But you can put the late99 air cleaner assembly in the early99 truck. The only three aftermarket air filters that work on the early99 are the AFE stage 2, the AIS and the KWIKK 6637.

The early99 track rod has smaller mounting bolts than the late99-03.

The early99 has shallower rotors than the late99-03.

The early99 has shorter hub-bearings than the late99-03.

The early99 front axle U bolts are square where they go over the spring pack. The late99 U bolts are round.

The early99 has a different pitman arm than the late99-03.

The early99 does not have the AIH like the late99-03.

The early99 does not have the automatic transmission fluid cooler in the radiator.

The early99 has no indicator light showing that "cruise" is on. Late99-03 has a cruise light that will come on when you set the cruise control. The early99 truck has the light in the dash already. A newer PCM(Yes it will plug in and will run better too) must be used to make the cruise light illuminate. It is a green light on the right side edge, half way up.

every thing that is painted orange (on the left) are 99.5-03...non painted (on the right)is early 99



the turbo on the left is a 99.5-03 turbo.it has the wicked wheel in it..





these are early 99 plenums. the 99.5-03 plenums are wider, taller and have a 3" hole for the boots..early 99 are 2"



best pic i have for a 99.5-03 plenums... sorry

Excellent description

 

thanks.... you can put all the 99.5 parts onto the early bird...as you can see in my sig i went above that lol

 

Thanks for the info

 

dang Ron, do you ever get to drive it....lol...

 

50k miles in 4 years....last winter and the rest of the winters i own her she will be parked... 198k on her right now...

 

Outstanding info! A big thankyou for posting this from a new owner of a E99.

 

Welcome to FTE and thank you for using the search tools. There is a ton of awesome stuff that you can mine from here if you have the time to do some reading...

This was an awesome post that I had forgotten about....thanks for digging it up.

Here is a tech sheet that talks about the 99.5 changes to add to your collection of data.

 

I'll just add a word of caution when replacing parts on a late 99. Mine doesn't have rounded U bolts, radiator cooling for the trans, and had e99 passenger side hpop line, which is actually easier to remove/replace than the newer one. I think at the change over, Ford used up remaining inventory. And no, the previous owner didn't repair anything because I'm the original owner.

Edit. I forgot, front sway bar, pitman arm and possably steering box, brakes, and who knows what else. The name Frankenstien comes to mind.

 

Thanks for the tech sheet Greg. It will come in handy, I'm sure. So much to read up on... Sure glad that FTE is so readily available as an oustanding resource.

Now someone correct me if I am wrong but I think these things only apply to the 4x4 and not the 4x2 ???
The early99 track rod has smaller mounting bolts than the late99-03.

The early99 has shallower rotors than the late99-03.

The early99 has shorter hub-bearings than the late99-03.

The early99 front axle U bolts are square where they go over the spring pack. The late99 U bolts are round.

The early99 has a different pitman arm than the late99-03.

For some reason or maybe I read something somewhere that the Early99 and late99 DRW 2wd trucks had all the same rotors, bearings, and pitman arm. I am confused on this?? Any of you guys with E99 4x2 DRW run into any of these issues??

 

BadDog, mine is a 4x4 drw, I began finding the differences with sway bar bushings and the hpop lines. Then just looking at things like u bolts out of curiosity after reading threads like this one. I'm always "looking" at things just to be familiar with my truck for future reference. It also helps me to know what guys are talking about on here, or if I need to do something.
