question about friction modifier
The first question is do I even need it? I read the manual and it said nothing about it. the sticker on my door jam has the code H9 which I am almost positive means I have a ls rearend. The next question is how much do I add and where can I buy it? thanks the truck is a 2003 FX4 F150

4 oz modifier is for a complete fluid replacement. The cover does not use a gasket, you use silicone sealer, also available at the Ford dealer. Some people have had good luck with generic sealer, but others have had leaks. It's probably more important to prepare the surface and apply it correctly than to use a specific product, I believe the stuff at Ford is made by Permatex.

Didn't really want to spend more money than I had to right now. Do I have to pull the cover off to drain the whole thing? sorry I am not used to working on my own truck. Another thing I have noticed is that I have a whirring noise coming from my truck. I thought it was the rearend because it has been seeping for a while, But it sounds more like it is coming from the front of the truck now, any ideas?

I was worried that the fluid was getting low and I was just going to add some until I could afford to take it apart and reseal it the proper way. I am going to eventually drain it and reseal it so it doesn't seep out anymore. I asked about friction modifer because I was worried I would harm the truck by just dumping some gear lube in there if I added any. I have 52,000 miles on the truck
