OK, when my JK was new the BLD system worked fine. I could crawl up slick rocks and it looked like all 4 tires were spinning (slipping actually) but all 4 tires would get power, it would switch between them but it would work.

...now after some abuse... it doesn't seem to work anymore. every time i get stuck only one wheel per axle is spinning, it's like the BLD stuff is just broke?

anyone else have this issue? could it be bad sensors? too much mud on them?
