Hi,

Does it have a limited slip I believe is the correct question, jack the rear up spin the tire by hand if the other tire spins the same direction it's got a limited slip if it turns opposite then open.

Or look up the build sheet

Regards,
Jim

It's saying not a vin
If you are copying and pasting, you must have a space at the start or at the end of the VIN. Make sure there are NO spaces or it won't recognize it.

Or a trailer hitch?
OP could have a hitch without the towing package. It could have been installed after the fact by the original owner. A hitch alone, is not a true indicator of having the tow package.

Just use a Diff lube, that already has the LSD Additive in it. Most do, and it will say it on the bottle, but this is only needed for LSD, BUT WORKS FOR EITHER, OR. Also go with a 75W110 Diff lube/oil in the front, and 75W140 in the rear. This viscosity in the rear, will work with either towing, or not..FYI I use Lucas, but there are plenty of different brands available.

Use 75w140 no matter which differential it is. Most decent brands have LSD additive in them anyway.

Are there wires by the hitch? If you canā€™t hook up electric to the trailer you donā€™t have a tow package.

If you have a hitch only itā€™s pretty simple to install the wires yourself. The electric should be there behind one of the rear wheel wells. Just add a trailer wire harness.

Agreed. But it's pretty easy to tell if an aftermarket hitch has been installed or if it is a factory set-up.
