I am trying to figure out if my traction-lok is going out.Did some searching but couldnt come up w/anything.Its a 98 auto w/4.56 gears,and 78000 miles on it.When I drove this thing in the snow,the back end was all over the place so it seemed to be working.But recently I was at a light and started to do a burnout while holding the brake and I swear only one wheel was spinning and the back end didnt move sideways at all.When I do that in my 93 or 99 the back end will start to come out as soon as they start spinning.Any help is appreciated.
