Sport trac 5.0 plans

[Richie18]

Appreciate the info, good thing, i thought it was going to be slightly easier than that, but no problem, just adding it to the list.

Was wondering if you i could get some more info, was discussing today about the swap and the bw4406 transfer case and even the transmission. What will have to be done with the crossmember to make this fit right?

Something would have to be done i'm guessing of course, but are we talking something very custom or will the parts the donor explorer work or have to be slightly modified?

The 5.0 / 4R70W / BW4406 should bolt into your chassis using stock 5.0 Ex mounts although the AWD trans mount is rather wimpy for the weight of the 4406. Get a front driveshaft from a 4.2/4.6 F150 or 4.6 Expedition/Navigator and mate it to the front diff with an adapter U-joint. Find a compatible rear driveshaft or modify yours to fit. Cut a hole in the trans tunnel for the manual linkage and wire up the 4x4 cluster indicators.

With the exception of the rear driveshaft, everything else in the various Gen2 Explorer manual BW4406 conversion threads on this site should apply to your ST. Since you would probably be the first to do a ST / BW4406 , you would need to be prepared to deal with possible clearance issues to the exhaust, frame, fuel tank, underbody, etc.

With all the info i am getting closer and closer. I'm starting to feel a little more confident with the project, i appreciate the tolerance for my lack of knowledge on the subject.

The conversion which others have done have all used bolt in rear shafts from 5.4 Navigators or Expeditions(4WD). Those are just right for a 95-01 4dr, so check on your OEM length, versus the 95-01 4dr. There may be other shafts to be just right, the 4.6 trucks like those 97-01 models are longer shafts, they have smaller rear ends(shorter). Check on the length difference there, and those measurements may be in the BW4406 threads. Regards,

You can probably get get one lengthened for under $200.

 

[CDW6212R]

Well take the measurements, and if a match isn't found, start with a slightly long unit.

Since the BW4406 is so much longer front to rear than a Ranger/Explorer T/C, I had a shop shorten my stock Ranger driveshaft. Something similar would probably work on the Trac too. Cost to modify the stock shaft was around $130. That includes the fixed yoke, U-joint, cutting, welding and balancing. The 06 Navigator T/C slip yoke was $19 new on eBay, probably $75~100 at a dealer.

Exactly. Some Rangers from 1998~2001.5 did the VSS correction/conversion in the GEM. My Ranger still has its original GEM for its timing functions but uses the added 2001 2.5 GEM just for the VSS conversion.

It is possible that the GEM from a 98~2000 RABS Ranger might also work. I chose the 2001 2.5 because, to the best of my knowledge, it was the only time on any RBV that the factory had the 4WABS and the GEM connected to the same input from the rear axle ABS sensor.

Before getting around to adding the 01 Ranger GEM, I had also tried two 4WABS Modules - the original for the Ranger's 4WABS plus another from the 5.0 Explorer just for the speed conversion. That didn't work - apparently the rear axle ABS sensor could not supply two 4WABS Modules at once.

I put a lot of time into this because I didn't want to give up the EBFD proportioning on my Ranger when I did the 5.0L conversion.

Hi. I found this old post and would like to try this fix. I'll need the pinout or wiring diagram for the 2001 2.5L ranger GEM. Can you help? I just put a 2001 Mountaineer 5.0L in an early Bronco. Now I'm hooking up the cruise control from the 01 in the Bronco and found the 4wabs converts the signal and I think this fix will do the job without trying to use the 4wabs stuff.

I read this whole thread, but I am still curious. I know the the VSS signal was different from the early/late 2001 but in all the 2001 Sport Trac diagrams I have looked through I've never seen anything to do with an g-switch sensor for the abs, as the explorer has. So then would that mean the early 01 abs processed the VSS signal through the abs module without the added sensor? I am curious as to the part number for the early versus late 01 abs module for the Sport Trac, didn't they both have electric brake proportioning?
