4x4 M50D-R1 (HD) speedo pick up?

[ben_2_go]

I want to do a manual swap on my '01 Ranger. What years M50D-R1 for a 4x4 have the speedo pick up in the transmission? I was hoping the newer HD version could be set up with a speedo pick up.

Years for the M5OD 4x4 to have the pickup in the trans. None.

The 4x4 speedo pickup was in the transfer case. The 2wd had it in the tail stock for a long time (Up to 97 I think) but that piece is replaced by the extension housing on the 4x4 version.

None

Ahh yeah that's right. I'm looking for a 1354m T case. I know the earlier models have the pick up in the T case. Would it work to drive the speedo sensor in my '01? I may have to look at a 1354e?

 

[adsm08]

Should. Its all the same stuff, manual or e-shift doesn't change that part.

Cool thanks.

Am I missing something?

A '01 should not have a speedo port hook-up at all, From '98-on, they used the ABS sensor on the rear axle to determine speed and shift points, etc. So it should not matter whether you swap in a unit with a speedo port or not (other than you'll need to figure out how to plug up the unused hole if you do get one that has it).

That's the thing. I have to get speed reading from somewhere. My rear axle will be changed out to a 9 inch. I was hoping I could pull the sensor out of the axle an plop in the side of the T case. I was thinking some of the early to mid 90's had the speed sensor in the T case. Maybe only some 2wd had it. I may have to figure out a way to use a ring and sensor in the housing between the trans and t case. I really don't want to lose the instrument cluster.

Ah, ok. You didn't mention the 9" (what's wrong with the Explorer 8.8"?)

I have seen tone rings mounted to the t-case rear output flange (or teeth machined into the edge of the flange itself) and a sensor installed on the rear of the t-case. Maybe something like that could work for you. You'd need it to provide roughly the same # of pulses per foot of forward travel as the ABS sensor provided, but it's been done that way before a number of times.

As for t-cases with ports, anything before '98 should have one, and I've also seen a 2010 2WD that had a (different type) speed sensor mounted on the trans tailhousing. I would assume similar-year 4x4s (probably 2010-2011) also would have it on the t-case, so another option you can look into.
Pre-'98 t-cases have a different front output than yours, so you'll need to change your front driveshaft too if you use an earlier one.

Hope that helps

Thanks. Yes, that helps.

I have been coming across some deals on 9 inch rears and TTB 44's and TTB 50's. I'm hoping to build a full floating 9 inch and front 609 knock off. For my intended use, it's overkill. I'm not a hardcore off roader any more. Some places I go are pretty rough and washed out. I'd rather build it once and be done.

I would just keep the 8.8 you have instead of reinventing the wheel... maybe a 31 spline Explorer 8.8? That would be an easy upgrade. You just don't gain much with a 9" and what you're talking about is all custom stuff that you can't buy off the shelf in an emergency.

I wheeled with a guy years ago who had a Bronco II that had a narrowed 9" in the rear, custom length chromoly shafts, etc. Broke the drivers side shaft, we had to weld it on the trail to get him back to camp and then he was not able to wheel the rest of the weekend. Maybe a rare situation but if you use common parts, you can pick up spares at the junkyard any day of the week for cheap. Just sayin. My 8.8 has been beat on hard in the rocks for years and never failed, a 9" swap is the last thing on my mind.

Also for what it's worth to plug the speedo hole on a t-case or trans for that matter, you can pull the speedo cable out of the gear assembly, fill the hole full of RTV, and put it back in place. The cable is just clipped in and comes out easily.

I don't have the good ole 8.8. I have a 7.5 rear that's leaking around the tubes where they enter the differential. It's also a lot long in the tooth with 250,000 miles and iffy gears.

The way I plan to build the 9's, I would be using off the shelf JY parts split between the 9-inch 3rd member and the d50 outers. Axle shafts may have to be custom. That's OK tho. I'll have to go back thru my stuff and find the info. There's a way to do it without doing full custom axles. I just can't remember the details. I'll only be sporting a stock VW 1.9TDI. I'm not building a high power hardcore rig. The axles would be more for peace of mind that I wouldn't break something while off on rough unmaintained roads. I doubt I would break a d35 and 8.8. The 9's will be there in the future if I decide to go with a stronger engine. I doubt it tho. I need something akin to fuel mileage.
