Thanks guys. I looked at it with an inspection mirror a while back and it looked OK. I just had a chance to go out there and look at it again. I used a nub from the end of the old cable and the driven gear would not turn by hand, so that was good. I reattached everything and I was very careful...

It keeps getting better and better. I connected the new cable directly to the xfer case and went for a drive. Nothing. So I had my tools with me and I disconnected the speedo so that I could see the cable. No rotation. Put my fingers on it while I drove. Nothing. So my guess is that the 39T...

Finally, an update on this. It's been raining every day for a week. I just put everything back together with the new driven gear, housing, and cable. I have no reading on the speedometer. This doesn't surprise me though, because I noticed there is nothing driving the speed adapter from the...

It has the stock grey sleeve. I'm still waiting on the order of the gear and carrier that I posted above. I'm still planning to try it with the adapter so I don't have to open the case. It may be the weekend before I can follow up.

Didn't the M1009 have 3.08 axle ratios? As a spot check, unless the stock gear was way off, if using the adapter, I can do the ratio of the tire diameters and apply that to the gear ratios I would think, since that's a simple linear ratio. That gives me 38.9.

That was my initial measure using a tape. I just had someone help me hold a drywall t-square against the tire center with another square on the other side. The diameter was 32 11/16. I think that's pretty accurate. @Sharecropper

I finally pulled the driven gear and housing late yesterday. Everything looks standard. Grey drive gear, yellow driven gear. I used an inspection mirror and the inner gear looks and feel fine. I soaked the adapter in ATF overnight. I think I'm going to just bolt everything back together at...

Yes. My Dad went to UK and my Mom was at one of the community colleges in Paducah, where my Dad grew up. We moved around shortly after I was born but I landed in ATL in 1993 to go to school, then got married to a woman who was born and raised in Alpharetta. I lived in the Smyrna area for a...

Oh, also my rubbish comment was about ChatGPT and Grok. I am finding their responses useless for identifying correct parts.

@Sharecropper please don't be offended. I really appreciate the guidance and the high rez pics. We are apparently going through monsoon season here in GA and it's been slow going taking parts off since my truck is parked outside. I also run a business and have events with my kids so I have...

After spending too much time on this, I think it's all rubbish. I don't think the M1009 can delete the reducer. The lowest we can go, I believe, is 34 teeth which will indicate 73 mph at 60 mph actual.

Referencing https://www.steelsoldiers.com/threads/speedometer-adapter-assy-6-m1009.70087/ I've been bouncing this off of ChatGPT trying to get the current part numbers, most of which are wrong. What I find interesting is that it made the recommendation of just removing the adapter box and...

It looks like the updated PN may be 88959481. Still trying to confirm.

See above. There is some kind of horrific graphite lubricant gunk in the reduction box that is likely 40 years old. I'm considering pulling off that unit, disassembling it, and throwing it in my ultrasonic cleaner. At this point I'm not focused on an accurate speedo, but my questions now are...

Apologies. It's an M1009 and it does have a reduction box on the side of the xfer case. I missed the intent of the original reply. Just assumed I had mentioned M1009.
