We have the G80 locker in the rear of our suburban...well now its toast and we have no clue what to put back. Can't seem to find the replacement...dealer said its discontinued. We really want something similar back as far as a locking differential. We are not off roaders but do jaunt through the country on occasion. Any ideas??

 

I had a powertrax "noslip" in my first wrangler.. not the world's best street manners, but off road, it worked great...

 

It may be discontinued as a whole new assembly but parts should and re-manufactured ones should be available. Google Drivetrain and your location and you should come up with some shops that can get you in the right direction...
