After finishing a swap of a 2008 Dana 60 full floater into my 2009 with RSC, I've run into a problem. All the reading I did told me that 2008 was the ideal candidate - full floater will still offered, RSC was available, and it was the first year with the bigger brakes like I already have and this thread
seemed to confirm it. I knew that the 2008 rear had a tone ring with 60 teeth in the hub and that my 2009 had 60 teeth on the front. I ASSumed that the 2009 rear was also 60 tooth, but after swapping, test driving, and getting the traction control kicking in, I counted and found that the stock 2009 ring is 54 tooth.
I think I have three options, none of which I'm certain will work:
1) get the ABS module reprogrammed to accept the 60 tooth signal from the new axle using an Autoenginuity scan tool or maybe the dealer.
2) get hubs with no tone rings and have machined 54 tooth rings installed (I see these are made for Dana 60 swaps into Jeeps as 52 or 60 tooth so it should just mean getting a 54t made and the hub machined).
3) use a converter such as SpeedoDRD
as a frequency divider to convert the signals from each rear wheel sensor to what the ABS controller is expecting. My worry here is that doing this would cause the ABS to fail the self-test.
Has anyone successfully completed a similar swap? Or can anyone tell me how many teeth a stock 2009+ full floater has on it's wheel hub? My internet searching turns up the same hub I'm using as fitting 2009+ which raises my hope of just getting the ABS computer reprogrammed to accept the new axle/wheel speed sensor input.
So frustratingly close to finishing this...
