Limited Slip Axle

I was curious about if my blazer had limited slip differential or not. I jacked the rear wheels off the ground and turned them. One turned frontwards and the other backwards. I was told this is not. How hard would it be to change this to a limited slip differential? Also is the front axle a limited slip differential? My blazer is a 1990 4.3 V-6 2 door 4 X 4 sport.

Re: Limited Slip Axle

Sounds like you don't have one, but if you look at the codes in the glovebox they should show if you do have one. And I would check again with someone holding the other tire to see if it "holds" when you turn the opposite tire if the codes don't turn up anything. You could also tear off the rear diff cover and check it from there too!

Difficult? Not very. If you're like me and don't know how to do gears, then get someone to do it for you with experience. You'll end up paying for labor but it will be better off when the gears are set up correctly the first time. If you don't have stock tires and want to get your performance back then you should also consider getting lower gearing and have that all put in at the same time. It'll just save you one hassle later on down the line!

As far as the front, probably not unless someone added it before you got it. The front is almost always an open diff. So in reality if you had no LSD in the rear and an open diff also in the front, you can get your ONE-wheel-drive truck into a TWO-wheel-drive truck.
