Thanks, I thought that was the right box. I really don't mind the needle jumpin around, its the fact that I can't use my cruise control at speeds that the needle jumps. I drive 25 miles one way to work, and I tend to end up speeding when not useing cruise control.

In my case it was affecting transmission shifting as well. At highway speeds, the needle started bouncing from 75, back down to 10, up to 50, etc. Eventually it got so bad that the trans would constantly bang into and out of OD.... It was one of those "I wanna punch a puppy in the face" aggravating experiences.

Sorry, Bob,
The 'puppy-punching' issue must be brought up in a new thread...
Seriously, though, my silent question regarding the ABS thing was 'Where is the module?' After reading through here, I now have the answer. Thanks in advance. Will let you guys know how it goes.

Unplugged the RABS box behind the glove box, and seems to have fixed my issue. I'll know for sure in a half hour or so.

Well its official, I watched my speedo like a hawk, and on the 15 mile drive home I don't think it wiggled one bit. Cruise works nice and smooth again. So the fix for mine was free, just a simple unplug of that ABS box.

Earlier, tried to pull the sensor for the rabs from the rear, only managed to break the plastic tabs on the sides. So I rebolted it down and pulled the module. Got called off on an issue at the house, so I didn't get the chance to road test it. But, I have confidence because of the results in this thread. Thanks to all.

Yep, my rear diff sensor was stuck too. Hopefully you've fixed your issue!

Wouldn't this trigger the ABS light to come on though.

It has not come on yet, and I've driven for about 100 miles already.

I've had mine unplugged for over 500 miles with no issues.
