I checked with that overdrive company, their OD setup for my trans is about $3400!
That’s a pretty big investment, definitely something I would do only if I was sure I was going to keep the truck. At this point, just not sure. Need to do the brakes and get it rolling down the road first.

I really want to know my options though.

Also read something about these no-slip differentials causing the wheels to chirp when going around corners, is this true?
