Friction modifier? What the hell is that? Check the FAQ that lists those kinds of things...

Sorry...wasn't thinking. My axles don't use it and I forgot that some limited slips do.

Most of the time, you won't have any problems if you just use a gear oil that's recommended for use in limited slip axles. It will say that on the container. Sometimes, you might have to buy an additive, but don't do this up front...just change the oil and see what happens. If you start hearing a chirping from the rear, add a little bit to the pumpkin to quiet it.

Some do, some don't. I believe it was a factory option. I have a 2000 with the 30/35 combo, and 3.73 gears, and mine does have the trak-lock, so I use a friction modifier in the rear only, along with oil for limited slips. I'm not sure if the trak-lock came on all 3.73s or not. If you're not in a hurry you can always request a free build sheet and see what it says. The tag on the axle MIGHT say if you have it or not too. I'll go check mine and see if it does.

Just checked. The little tag on my pumpkin specifically states "USE LIM SLIP LUBE" so that's also how I knew I had it. See if it says it on your tag. It'll be the tag that is only held on by one bolt, on mine it's on the right side. As for RTV, I just used the black stuff, I think it just said RTV gasket sealant or something.

How about he determines whether or not he has a limited slip differential and then puts the proper fluid in it?

If you have stock differentials the front D30 is open and doesn't need the friction modifier.

Jack up the rear wheels and rotate one of them. If the opposite wheel rotates in the same direction you have the trac-loc and need the friction modifier. If the opposite wheel rotates in the opposite direction you have an open differential and don't need the friction modifier.
