I am just learning the intricacies of the explorer and therefore will not comment. I must correct the statement of Chrysler doing away with torsion bars in the 60's. My 1970 Road Runner had them.

Thank you! Poor wording on my part, I believe Chrysler STARTED using torsion bars in the 60s; how long they had them, don't know.

BTW, Explorer "intricacies" are actually nothing very out of the ordinary. Pretty standard Ford design technique; I really got pissed-off when Firestone insisted the Explorer rear suspension was responsible for the tires failing, and vehicle roll-over. Those Explorers had semi-elliptical leaf springs exactly like useage dating back for many decades. Pretty bullet-proof suspension for use with a solid rear axle!

Intricacies of the Explorer may be standard Ford design but they are very different than my 89 Dodge W150. I am a shade tree mechanic not a professional. This is the first Ford in my family. The only way I learn a vehicle is reading about it and hands on. Every vehicle is a little different in varying degrees and that is what I meant by intricacies. The little details that make things work.

not being a pro on this but after rebuilding a few t cases in 02 mm i beleive that the truck could roll when in park a hill because the viscous clutch land between the transmission out put shaft and the rest of the parts its the first piece you can see after the inputClick the image to open in full size. shaft

To say that the Exploders ended with the 02 model based on independent suspension is ludicrous. The front end on the 95 and later is a farce.
Clearly, someone is not aware of what happened to the Explorer after the 2nd gen years ('95-01). The '02 Explorer was ranked as the "Worst Vehicle on Record" by CarComplaints.com. It was like castrating the noble truck heritage the Explorer had completely. Keep in mind that the original Explorer (1st and 2nd gen) were derived from the venerable Ford Bronco. 2001 is definitely where it ended. 2nd gen and earlier models had 1/2 ton running gear on a Ranger truck chassis. 3rd gen and onwards were no longer trucks.

I'm not sure how bad the Dana 35 based IFS really is. So far, I've been tearing around offroad at high speeds rather comfortably and made several deep water crossings, through mud, and light rock crawling with my stock '00 Mountaineer. Being an early Bronco driver as well, I do find the handling a lot better over the solid axle design and really like the precision of the rack and pinion steering gear over the old school worm gear steering box. The torsion bar suspension is pretty unique and I do miss looking at coil springs, but the truck seems to handle great, so no real complaints. The fact that these relatively small and nimble vehicles came packaged with the 5.0L, 4R transmission, and 8.8 axle is awesome... great little truck for recreational use.

Arrow Explorer Park

From 92 until now I have owned 8 explorers have had very good luck with all and never seen this park problem you folks are talking about. I had to overhaul one 2005 transmission and worked with the Park Prawel if this is miss adjusted badly it could cause a problem but it would also cause shifting problems in that it connects to the main shifting lever. It is located on the rear end of the transmission regardless of 2 wheel or 4 wheel drive.

The issue arises when you remove the front drive shaft on a 1996-2001 V8 AWD Explorer, no other models. it will allow the truck to creep down an incline (very slowly) due to the drivetrain not being connected. think of it as putting a normal 4x4 transfer case in neutral, it's kind of like that.

Must be the viscous coupling allowing the t-case to spin at the front driveshaft freely since it's missing.

Arrow Explorer Park

The park prawel is in the rear of the transmission before any other device so the shaft would have to turn between the transmission and the rear end for it to move and I really don't think it does. Unless one rear wheel is sliding and you just don't notice it. If you have a low tire on one side of the rear this might happen.

Exactly what is happening.

If the vehicle rolls when the front driveshaft is removed.. which is what I now believe to be true after seeing the t-case diagram, then that means this vintage Explorer is primarily a front wheel drive vehicle. I always thought it was the other way around but it would appear it's just another thing designed to make these more car like.

NO, it's not. The Explorer was RWD based from 1991 -2010, the new design in 2011 it changed to a FWS based design. The issue is the fully mechanical AWD transfer case, which provides without any slippage 65% power to the rear wheels and 35% to the front, but can provide up to 50/50 if enough slippage occurs. With the front shaft removed you have half of the drive wheels no longer connected to the transfercase. so the transmission is locked in park, but the transfercase (located behind the transmission connecting both drive shafts) is not connected to all the drive wheels as designed, this is what allows the truck to "creep" in park.


My old '00 V8 AWD doing donuts. The 8.8 rear axle with LS is the primary drive axle. The 91-01 Explorer was very much a truck.

Well the diagram suggest otherwise so I propose an experiment, on a truck that creeps with the front drive shaft removed does it do the same with only the rear shaft pulled? I suspect not but this would be telling.
