I just recently purchase a 1999 F-150 4x4 with a 5.4. As with most car dealers a high mileage vehecle is usually sold as is no warranty. This truck has 98,000 on it but sounds, runs and looks great. So i bought it My inspection before buying did not show any fluid leaks at all. After a 400 mile trip back home with it i discovered the driver side cv boot throwing grease at the fender well. Called the dealer and he was willing to send me a $100 credit for the boot. Now i'm usually pretty good at mechanical stuff but i m still trying to figure if i need a larger hammer or maybe larger wheel puller to remove the axle. Not sure if i'm holding my mouth right or not I have soaked the spline area with a good penitrate but no luck in it comming loose. What m i doing wrong? I even put the wheel puller on and had it real tight and at that point i gave the puller a good blow with a nice size hammer and still nothing. I have another question but i will post it in a different location. Thanks

 

The axle spline is a 'slip fit' and generally doesn't need a puller/press.. Most times just a bump with a brass hammer/punch after the axle nut is removed and it should slide back.. The CV joint will need to be seperated to install the new boot and at times will hold together tight, but the axle spline even if rusted shouldn't need a major push to get it to move .. But if you got lucky, and it's really stuck, than a beam puller, three jaw, or a puller that can give it a bigger push on the axle 'nose' is the best way to get it to move.. You want to avoid striking the axle/hub with a hammer so not to dimple the bearing race/s..
