BW 1350 ??'s

[TeamExploder]

I was curious as to how strong the BW 1350 because I've seen people that have them in their ranger and BII's have swapped them out for BW 1354's. I ask because my mom has an awd aerostar and was going to put a manual or electronic BW1350 or 1354 (which ever I can get) because I thought the mounting was the same on both so that either would bolt to the A4LD connected to the 4.0 correct? I planned on doing this swap so the van isn't too much of a gas guzzler. How complicating would it be to hook up an electronic shifted 1350 or 1354 t-case into the van? (I've never torn into the whole electronic systems). I already have a pushbutton module that I had as a spare for my old explorer so thats one less thing to get but I don't know what all else is needed to do it. Thanks for any help y'all can give me

The ONLY reason to switch to a 1354 is so you can put a beefier Dana 35 front driveshaft and axle in.

The 1350 model's strength is virtually identical to a 1354. But the front driveshafts are another story.

But NEITHER of these will work with the VERY DIFFERENT front driveline on an Aerostar.

 

[TeamExploder]

Why do you say it won't work with the front driveline? I don't know alot about the van I just assumed the drive shaft would work with the other t-cases.

Think of the Aerostar as a Chevy. The driveline has NO relation to Rangers. It's completely different.

The BW 1350/1354 transfer cases won't bolt to the Aerostar transmission, either.

 

[TeamExploder]

Oh....I thought people has used the aerostar A4LD in their ranger and explorers.

 

[MAKG]

Not AWD.

 

[TeamExploder]

Oh...ok...Thanks for the help.....sounds like I'd have to change the output shaft and everything to aquire the ability to even bolt up the normal 4X4 t-case if thats even possible which sounds like is going to cost more to do than what its going to save in gas.

Actually the 13-50 and 13-54 will bolt to the Aerostar
A4LD (90-95), 4R55E ('95-96) and 5R55E (late '96 and 1997)

the outpt shaft and T-case mounting flange are EXACTLY the same.

THE issue wiht the Aerostar tranmissions is the shift control on the tranmission itself which is not always compatible with Ranger/Explorer
transmissions

that all being said the DANA TC28 T-case used in the AWD aerostar
uses "slip yoke" REAR output (same size as 2wd A4LD )
and a semi-slip front output that is SIMILAR to
(yet not completely compatible with) the 13-50 front slip yoke.

Remember that in the aerostar the front differential is BOLTED to
the engine crossmember, so the driveshaft only needs to allow for engine/trans movement in the motor mounts, not suspension
movement like on the TTB rangers.

That isn't all of the situation, the front halfshafts of the AWD aerostars
are failure prone, so if you actually "locked" the front drive to the rear drive and got the van into "bind" as typically happens in a tight turn
something in the front end is likely to break.

Low range? I don't think that would be a good idea at all....

Particularly if your AWD aerostar is an early one (90-92)
the later ones (93-up) use an actual CV joint at the inboard end of the front halfshafts, the early ones use a single "cross" type U-joint.

the aerostar AWD system has a planetary center differential with an electronically regulated lockup clutch with a "center differential" built
into the T-case.

Put an AWD aerostar in "park" without chocking the wheels and try jacking it up... it'll roll away on you....

The AWD system works and works quite well, the system compares the
output of two speed sensors and providing that several other parameters don't interfere (brakes not applied, speed >8mph and <55mph and trans not in neutral or park) the system will engage for 3 seconds, then "peek" for 1/2second and if the slip reoccours will reengage for another 3 seconds.


I have an AWD aerostar they are suprisingly capable vehicles
The one I have now is my third AWD, it's a 1994, I previously
had both a 1990 and a 1991.

The only thing I think it really needs is a limited-slip rear axle.
To that end I'm building an 8.8" axle for it
(AWD aerostars got 7.5" rear axles, the 8.8" axles went into
the 4.0 2wd's)

Thanks for that information, if you think its not a good idea then I guess I won't mess with it, its a 93 Eddie Bauer, I was just going to do it so it could have true 2wd because I know with it having an awd t-case I can't just disconnect the front axle or else it will roll away. And I won't turn it into a 2wd because the reasons for having a awd van is so she can get around in the winter better but wasn't all that sure on how good they are on snowy roads or driveways that was another reason I was considering putting a normal 4X4 t-case into the van so that it'd have a 50/50 split when engaged into 4wd.

Well, you could fix the parking brake. Then, it won't roll away.
