Try TSB #LTB00478NAS2 (attached).

I would have saved myself a lot of time and money if I made a habit of checking TSB's as an early step in troubleshooting. I'm a late learner.

 

Thank you for answering I really appreciate what you do on here was hoping to find someone that has seen this, and solved it, if when I figure it out I will post for others.Have a great weekend.

 

I agree but this happened after I pulled the coupler changed oil, filter and replaced, so it seemed to me to be that something didn't like being touched, wire loom intact, but did notice a "crunchy" ground strap over the diff with part of the woven part separated, so I was questioning whether or not I was losing ground with movement of the strap. I'll look into the tsb some more but reeeeeally trying to avoid stealership, All the work I just did tires, tie rod end, alignment, fluids, filters just smoked the daughter's savings and that not the 150-labor charge. I gave her this vehicle after school ended because I am retired now and just share a car with the wife, so this is not a ride I would normally recommend for her, or anybody.

 

anyone know where G4d149-1 and g4d149c-1 ground from coupler boardlocation is terminated location so I can check for rusty, connection, in RI it's basically all that's left on this thing.
thank you
