So I have been driving my little black Liberty around on it's new axles... HP D44 Front and D60 rear. It's working out quite well, although I need to geta front sway bar on it :)

My question is this. It had an exciter ring on the third member in the 8.25 rear end that caused a magnetic pickup in a VSS (vehicle speed sensor), mounted ont he outside of the housing to send the speedo signal back to the ECM and dash unit. Obviously, my D60 swap is decidedly lacking in the facilities for this device so.... Does anyone else out there have a Jeep type vehicle that ran the speedo of the third member and.... what can be done to change it to run off the T-case? I still have the stock NV242-J in the Jeep. The output shaft housing has no provision for a VSS, but do other 242's have a provision for a VSS ont he output shaft housing? Anybody own a grand or TJ or something with a 242 that has the provision for the electronic speedo pickup on the T-case somewhere?

Any help here would be nice... I guess I could cruise down to Doug Smith and look at the vehicles on the lot.... but then I would have to avoid the Pirrana :D

Thanks,
-JJ

Older NP-242 cases do have the provision for the VSS on the rear tailshaft housing. I am not sure what could be different on yours, being that your's is a Liberty and the older ones would be either from a XJ, ZJ or some WJ's. I would think that you would be able to swap on this tailshaft housing and wire up your speedo to work with that.

Who did our 60? You can put a tone ring on it and weld a bung in the cover for a pick up. Or if you used a 60 center out of a Ford van, it would have a tone ring....
Charles at Rocky Mnt Axle should be able to hook you up.
Or try JB conversions, they have a variety of short shafts, and a lot of knowledge on what can be swapped in what.

I did the 60... and I ran...gasp... a Yukon spool. I know... kind of a silly idea for something I still drive around.

I kind of thought of adding a tone ring to the back side of the spool... I was thinking of buying a D60 ring gear spacer... machining the teeth in it... and running it bolted to the back side of the spool. Which would work out great with standard size ring gear bolts as I had to run 1/4 inch shorter ones for the spool. My diff cover is mader from 1/2 inch and 3/8 plate so there should be plenty of meat to weld a boss onto it. So I think we are thinking the same here pretty much... "idea #1"

Idea #2
As Brett says... I may be able to adapt the rear output from an older 242 to my Liberty version (which BTW doesn't even have the boss cast into the output bearing retainer...let alone have one machined... dorks). This could actually work out well if I could figure out the right combo of parts because I want to run a slip yoke eliminator kit on it anyway... If I could just buy the kit for a Grand 242 and also get the tone ring... I could be in business eh? Thoughts?

Thanks to all, Pics are to come soon... I didn't have a digital on hand so I took all the build ups with a couple disposables that are now down at Wally World getting processed and put on CD. I will post as soon as they are back.

PS, Bigchev, I think I'll skip the spoke idea :) besides... I bought BLs for it... hey wait! Maybe I could get tone from the bolts in the lock ring! :D :D

You don't need to use a ring gear spacer. Just get the tone wheel from a van 60, machine a small lip in the spool and the tone wheel wil pinch between the ring gear and the spool. Again, Charles has the know how and parts.

That sounds like the best solution yet... after your first reply I figured that the tone ring on the Van was machined into the carrier... I didn't realize that it was something that was removable...kinda like a ring gear on a standard trans flywheel?

I will contact Charles and find out more... If the tooth count is pretty dang close (hopefully a few more teeth than my liberty's stock one to account for the 315's) I should be in business. I can mchine a recessed lip on to accept the ring no problem.

You don't by chance have contact info for this shop do you? I have not heard of them before. SLC or Utah county?

Thanks for the ideas and info!

I tried 487-0067 and got re-directed to 296-2898, but a modem or fax or something answered that number....

Yep, that was me! I figured that was you... there's not too many solid axle Libby's running around! :D

Thank you sir, that got him. I actually just went out to his shop yesterday and picked up a tone ring from him. Turns out that Charles is the neighbor of the guy from work I took with me... go figure.

On a sad note... Charles mentioned that he is closing down his axle shop in a couple of weeks. It's just not turning enough profit to warrant keeping it open. After talking with him at length and observing his operation, I would say this is a loss for sure. Our hobby needs guys like Charles around. Maybe everyone could flood him with enough work that he'd have to stay open :D :D

Thanks,
