An 8.8 out of a 2nd gen Explorer has provisions for an ABS sensor. Problem is, the tooth count on the reluctor wheel is different than the one on F body diff.

Does anyone know if there is a reluctor out there that can be installed on the 8.8 to keep the ABS?

Best bet would be to have one laser cut and machined on the ID to press fit on the ring gear. If I hadn't pitched mine I could measure it and send you a CAD file so you can have one cut locally. If you have the 8.8 reluctor all I need is a few basic measurements, and of course the number of teeth on the 10-bolt unit. LMK

This 8.8 link here shows 108 teeth and 8.5" OD. I think the 10-bolt ring has 106 teeth. I didn't think about it at first but I assume the reluctor ring is mild steel. If it were magnetic it would pick up particles like the drain plug.

That is one heck of an offer Hiltsy. I can do better than get you measurements...I may be able to send you an actual reluctor wheel. Let me see what I can scare up for you.

Man...two teeth off, huh? That is darn near close enough to work.

2T off - close, but no cigar. 106 is the number I found, you might want to do your own research to make sure. The thing you have going for you is that the 10-bolt & 8.8 reluctors look about the same as far as tooth configuration. You still have to see if the sensors are compatible. Here is a quick model of an 8.5" OD x 106T reluctor. I found this 10-bolt ring on eBay for reference.

I will use the F body sensor. I haven't measured the two yet, but I will either drill out the 8.8 hole to size, or build a sleeve. Then you just have to set the depth correctly. With the housing on the floor, it should be easy to do. Tough part will be the reluctor wheel.

I didn't think about going that route. At least you won't have to worry about compatibility between the sensor & ABS.

Bringing this back from the dead, I'll be doing an 8.8 swap in the next few months and I want to keep my ABS can anyone make me a 106 tooth reluctor wheel to fit the 31 spline 8.8 carrier?

Working with another member here, I have a tone ring designed and I can get one made or provide the CAD file so you could get one made locally. Not sure how to adapt the 10-bolt sensor to the 8.8 housing yet. Send me a PM.

The sensor should be the easy part hiltsy. You have done all the hard work. I looked at it once...but can't recall exactly what was needed. But you already have a hole in the 8.8 in the proper location. If it's a different size hole, either drill or sleeve to fit. If the depth needs to be adjusted up, then use a spacer. If it needs to go down (I don't believe it did), then you would have to figure out a way to machine the mounting service down. All in all, very doable. But I'm not so sure you couldn't get away with the 8.8 sensor then just adapt the wire harness to the Ford plug.

Ya I've thought about that, but ABS systems seem to be pretty particular and you know the 10-bolt sensor will work if it gets the correct counts / rev.

I wonder if I could get a picture of the wave pattern for each of them...

I have the scope...just need to find time to go out and do it. I'll bet there are pictures out there already. I would look at something like a 98-01 Explorer.

hey oldcobraguy, I'm doing this same build for a guy with a 3 channel. what did you figure out about using the ford sensor or did you have a new ring cut? dang shame they all aren't 4 channel like mine, lol. thanks for any help.

I'm sorry to say I figured out zip. I haven't even thought about it. What makes me mad is I rebuilt the rear end in my car a couple weeks ago and should have taken the time to see what it would take to use the GM sensor in an 8.8.

I've been working with Hiltsy on this project and machined a ring off the cad file he sent me. The 10 bolt sensor will fit right in the 8.8 housing all you have to do is drill out the mounting hole on the sensor about .100 bigger. The problem is the length of the ten bolt sensor is much shorter. Hiltsy designed the ring so that it has a larger O.D. for me. I had to grind the inside of the 8.8 housing to make it fit. I'm still working on completing the rear end and my welder has been out for the past week, but I'm hoping to have it done this weekend. I'll update after I get it all back together and make sure it works.

sir, you and hiltsy are the men. please keep me posted on this. if it works and you would like to sell them I would buy one immediately and more as they come to me. I'm building my first one now and looks like at least three more. thanks again.

That was a great solution jankags. But I have a feeling the Ford sensor would work if you swapped or converted to the Ford connector. I could be full of it too though!

jankags

I'm not 100% sure if the ford sensor would work or not, but when I'm ohm'd both sensors out they read differently. Which leads me to believe it would not work with the gm system. If I get the time in the near future I may try and make another ring with the same O.D. as the ford ring and try it.
