Got the PM Chase. Been trying to install new gauges between rain showers.

Everytime I post this it get corrected but this is this week's version.

Some differences between Early 99 and 99.5

Credit to Chase (aka superduty4x4), Ron aka (Ron's Power Stroke) and in Bold credit to Jet (aka SolidGround) RIP.
It I did not credit everyone envolved with this I apologize.
Early 99 has a wicked wheel stock from the factory. And much smaller turbo (spools faster, though)

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 HYPERLINK "https://www.ford-trucks.com/rx98192zju/kwldirect.php?kwid=302"intake heater relay side by side. Both relays are above the passenger side valve cover toward the front of the truck.

The early99 has a totally different air HYPERLINK "https://www.ford-trucks.com/rx98192zju/kwldirect.php?kwid=696"filter that is not inter changeable with the late99-03 (except for DRW trucks) . 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. (except for DRW trucks)

The early99 has shallower rotors than the late99-03. (except DRW trucks)

The early99 has shorter hub-bearings than the late99-03. (except DRW trucks)

The early99 front axle U bolts are square where they go over the spring pack. The late99 U bolts are round. (except DRW trucks)

The early99 has a different pitman arm than the late99-03. (except DRW trucks)

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

 

what are DRW trucks?
What is the track rod?
Can the rotors be replaced with better rotors without degrading drive ability?
Is there a disadvantage of having a different pitman arm on the early vs late?
Anyone know where I can get a replacement PCM for my early 99?

FYI, AIH mean Air Intake Heater

Sorry, I thought I'd ask questions since I had a couple as well.

 

DRW = dual rear wheel
Track rod = panhard bar. It's the metal bar going from the driver's side of the frame to a bracket on the front axle... helps keep the axle from walking side to side.
Rotors = you can get upgraded early 99 rotors (Powerslots, HD parts from your favorite parts store) or if you get real ambitious and want to drop coin buy late model unit bearing assemblies and rotors.
Pitman arm = AFAIK no advantage/disadvantage either way.
Replacement PCM = junk yard or Car-part.com

 

thanks bud, you're a wealth of knowledge, I have a feeling I'll be learning a bit from you

 

I'll teach you stuff about your truck, you fix my compy when it breaks

 

lol, sounds like a plan
