How is the rear speaker cover removed from a supercab fx4 f150 2004

Not sure about the Ranger but the Ford Galaxy used speakers of around 6 - 8 inch diameter.

I suggest you remove a door card to check rather than try to estimate from the size of the speaker grille. This is because best practice is to make the hole significantly smaller than the speaker.

Sorry I couldn't give a definite answer, I just thought you should hear from someone...

remove speakers trim cover then remove speaker screws.from top or remove rear side trim remove rear shelf to remove speakers.

Look for a 30 amp fuse in the central junction box- I think that is the box near the battery.

Front Door Trim Panel

First thing is to make sure you chock the front tires so the truck will not roll. Raise the rear end and set it on jack stands. Put the transmission in Neutral and make sure the parking brake is off. Remove the rear tires and disassemble the brakes on the side with the leaking seal. Place a drain pan under the rear differential and remove the cover. Remove the differential shaft lock bolt. You will need to turn the drive shaft by hand to access the bolt. It will be on the right side off the spider gear housing. Only use a 5/16 or 8mm 6 point box end wrench to remove the bolt. After you remove the bolt reach on the top of the spider gear housing and push the differential lock shaft down to remove it. Make sure the spider gears do not rotate after you remove the shaft. If they do you will need to realign everything to reinstall the lock shaft. Push the axle shaft in enough to remove the "C" clip from the tip of it. The axle will now slide out of the rear end. You can use the tip of the axle shaft to remove the axle seal. If you're changing the bearing as well you will need a slide hammer with axle bearing adapters to remove it. You can use a socket and hammer to install the new bearing and seal. Be careful not to damage the bearing and seal. I recommend packing grease in the back side of the seal. This helps prevent the spring on the seal lip from coming off. Assembly is the reverse. Clean off all the gear oil from the differential cover and the axle. You can use RTV as a gasket if the OEM gasket is damaged. Fill the rear end with new gear oil of the proper type. Refer to your owner's manual.

If you have the FX4 option, it does. The FX4 models are basically a standard 4x4 with an Off Road package that includes a few extras like upgraded heavy duty Rancho shocks, limited-slip rear differential, added skid plates for the fuel tank and transfer case, and two "FX4" decals on both back bed-sides instead of the standard "4x4".

I checked the Ford truck forums and found nothing out of the usual for limited-slip differentials as far as having problems. Older years yes, current year don't seem to have problems.

Sounds like the front wheel hubs are not locking in.

The bolts should not be covered by anything. You can locate them on the back side of the calipers where the bracket wings down toward the axle.

You have to remove the backseat, the back upper sidepillar trim and then the cover over the speakers.
