So how do u fix the rattaling in front hub

One of the better bargains in car service are front-end alignments. IF you go to a reputable place they will inspect the front end components before doing an alignment. The really good shops will have a separate repair area for time consuming repairs so the alignment rack can be kept on schedule for the next alignment.

Some shops will diagnose and send away vehicles which they need repaired before doing an alignment and other places will perform an alignment and tell you what needs to be fixed if the bad component does not affect the alignment they are doing.

It would help if you first discussed fees if they can not finish the alignment. People do have to be paid and shops can not stay in business if several vehicles come in each day without paying.

Now tie-rod ends can produce a good thud as well as ball-joints. The hubs you mentioned can do this too. Worn calipers can thud rocking on their slide-pins. Hope this helps.

Why not check if its your exhaust rattling give it a shake and see
Or can be a loose heat cover

there's a couple of things but it will require a transfer case rebuild
either it is the drive chain in the transfer case that broke or ford also installed a plastic shift disk that breaks about every 600 miles of 4X4 use it is part of the planitary set

YOU NEED STRUTS

There are some special 4 tooth and hex sockets for removing the nuts inside the hubs of the truck.
YOu can find these at NAPA or maybe AutoZone or Advance. I would go to NAPA because they more than likely have it and also know something about repairing this assembly.
Ford uses Dana front end parts and NAPA has original Dana parts in stock... so it is as good as or better than original and they would have the tool for it.
Be careful and follow the procedure exactly for putting the front hubs back together.
YOU CAN RUIN THE FRONT END OF THE TRUCK IF YOU DO NOT PERFORM THIS SERVICE CORRECTLY.
And trust me... many of the idiots working in repair garages do not know how to do these older 4x4 hubs either... ask someone and read the books for the right procedure... some of the older mechanics may show you how to do it. Ask

There are issues with the 4x4 system I.w.e ends ingesting moisture/water into vacuum actuation system causing no 4x4 or ratcheting outboard I.w.e ends. (Even if you don't go 4x4'n ) pull off vacuum hoses @ I.w.e ends and check for moisture/water/rust also the I.w.e is not part of the wheel bearing itself It is the part on the axle side (inboard) of the spindle. (EVEN DEALERS CAT LISTED WRONG)Many shops just replace the wheel bearing side this may fix the symptom but not the true cause of damaged I.w.e. ! Check with a reputable dealer they should have info on this condition and repair procedure.


The integrated wheel end (IWE) system contains the following:

Vacuum reservoir
IWE solenoid
IWEs (spring loaded vacuum hubs)
Vacuum hoses
Check valve
The IWE system uses vacuum hubs that engage the front wheel hubs to the front half shafts or disengage the front wheel hubs from the front half shafts.

The IWE solenoid receives engine vacuum from the vacuum reservoir.

When the 4-wheel drive system is in 2WD mode, the 4x4 module (PCM)supplies a ground path to the IWE solenoid to apply vacuum to the integrated wheel ends (disengaging the front hubs from the front half-shafts). In 4WD mode, the 4x4 module (PCM) does not supply the ground path to the IWE solenoid, vacuum is not applied to the integrated wheel ends and an internal spring keeps the front hubs engaged to the front half-shafts.

Good luck and check the vacuum line, start with the simple. Keep me posted, be glad to get your 4wd working again.

There is a possibility the axel U-joint is binding, this will put side load on the hubs and keep them from working properly. Turn the steering wheel either far right or left and with front of truck off the ground or the front end disengaged, see if the axel shafts turn free, both sides. If there is binding the U-joint(s) will have to be replaced.

Check the heat shield to the exhaust manifolds, good chance that the bolts on them have rusted off or is loose causing the Heat Shields to rattle making the tinny rattle noise. Good luck and keep me posted, be glad to know if that's making the noise, and if not we can look at other things.
