Yet another early late 99 thread (Chassis cab specific F450)
Looking to order some front end parts. My track bar needs bushings replaced now and I want to have brakes and wheel bearings on hand for when I need them. I would like to order the parts ahead of time and order the correct ones. I had assumed my truck is a late 99 based on the turbo and intake when I bought it. It was definitely not early 99 but i have since switched engines. Now that I have been reading I think I have the early suspension BUT I also read the chassis cabs are different. Here are some pictures:
So can I tell for sure what parts to order?
Track bar or bushings.
Front Brake rotors.
Front wheel bearing assemblies
Thanks for any help.

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)
Since I have a DRW does that mean I already have the late model wheel hubs and rotors? I just wanted some confirmation.

Early 99 has a wicked wheel in it 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 intake heater
relay side by side (along with early '99 CA models) . 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 (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. (except CA model)
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.

If I missed a credit shame on me and I apologize.
That date indicates E99. But, if you want to upgrade to 2000 stuff, just do the 2000 rotors and the 2000 wheel hub units. You just can't mix the two.
Sorry I meant to ask does the chassis cab even follow the "date rules"? Some info I found says "except DRW" after most of the suspension differences. What do the DRW trucks have? I guess mine came with the early suspension and late engine?
I am not entirely sure. Some of the other more knowledgeable guys will chime in. What size are the plenums? If they are smaller, you have an early build. On the spyder, it will go from 3" to 2.5".

Thanks. I was having trouble finding pictures since most are 250 and 350. Seems like the chassis cabs followed the same changes.
Any way to tell for sure what hubs and rotors I have? When my brake pads are about done I'll do new pads and rotors and want to match my existing bearings but they may have been changed before I bought it.
Take the wheels, calipers, and rotors off (yes, the dual wheel spacer is a pain) and measure the thickness of the wheel hub flange. 10mm is E99 while 13mm is 99.5-up.

The flange is with the 8 studs for the rotor and dually adapter to bolt on correct? Or the flange where the bearing assembly bolts to the axle? I have always wondered which flange it is referring to. Thankfully I have not had to change one yet.
Also would a 4x4 bearing work on the 2wd monobeam axle? Seems like it is the same dimensionally.
I would say the flange with 8 lugs, but on the older 450/550 there are two 8-lug flanges. The flange that needs to be measured is the one containing the 8x170, not the 8x225 (why I said to remove the adapter and caliper/rotor - life can't be too easy).
I don't know about the wheel bearing assembly interchange on the 2wd monobeam though although I'd ASSUME that the only difference would be some kind of plug through the middle. We don't have any 2wd stuff around here for me to dig through.
Whooops...I did not realize that the two tags each had differing mfg dates. I was going off of the top on that had 01/99, but then saw the 03/99 on the chassis. That make explain why you have late 99 engine parts.

Doing a little more digging....
Yes, the 4wd unit hubs will fit in the 2wd monobeam knuckles but they'll look goofy with a giant hole through the center since there's no shaft going through.
