front differential service question
guys I had my front diff serviced today, I have a 2000 F150 5.4v8 4x4 with 73k miles on it. When they pulled the plug the magent had less than half a finger worth of crud on it( crud being grease, metal pieces, etc that will stick to the magnet) I am unsure if the diff has ever been serviced before. The guy was telling my I need to take to ford and have them look it over.
My question is this, I figured some crud will get in there, currently my on the fly( I think it is at least, selector on dash) is fine, when I shift into 4 hi, there is a slight bump with the cluster comes on, I was told that is normal, just the gears locking in. So how much crud should be there.
I plan on waiting about 1K miles when I am due for an oil change,and have them check it again.
Any thoughts, ideas, or input?
Thanks
James

How often do you use your 4 wheel drive? How hard do you use it in 4 wheel? Do you really romp on it or just go easy, like trail riding?
I would probably just wait till you bring it in for an oil change.

You have to figure that when you are in 4 wheel that your front and rear tires are locked together through the diffs, t-case, trans, basiclly a bunch of gears that don't have a whole lot of give to them. Any difference on the rate of speed at which your front tires turn as compared to the rears will have to be made up somewhere. Off road the wheels can slip in the dirt. The dirt has some give to it. On the pavement your tires have alot more traction, less give, which means there is a good chance of something binding up and possibly breaking. I'm not sure if that makes sense . Maybe someone else can explain it a little better then me.

on pavement, especially when turning, your drivetain will get bound up. You can do it, but you have a good chance on tearing up your tcase or twisting a driveshaft.

Why exactly? What does Ford say for it's lube service interval? Most front ends never get thier lube changed. As in 20+ years.
Unless you have an AWD that uses Dextron/Mercon I would not worry. Even then, it might be lifetime.
Though I believe in changing it anyways, lifetime or not. Fill plugs do get gunk on them and gunk does collect in the bottom of the pumpkin. It is normal.
