Rear axle broke and wheel came off. fixed it and same thing happened. rear floating axles have pin that broke!! 97 CREW CAB F250 Can this axle be replaced with another type.

replacing bearing involves removing axle your not replacing a hub but tearing apart axle 99 04 F250 Sterling Rear axle bearing replacement Pt 2 2006 Ford F250 rear hub axle seal replacement F250 Rear Brakes Axle Hub Removal Install 03 07 Powerstroke

Wheel bearings are designed for longevity. Their life expectancy, based on metal fatigue, can usually be calculated if general operating conditions are known. Bearing failures not caused by normal material fatigue are called permanent failures. The causes can range from improper lubrication or incorrect mounting, to poor condition of the shaft housing or bearing surfaces.

Inspect the bearings for these improper wear conditions, and for:

A. pitting.
B. rust.
C. corrosion.
D. Excessive clearance(play)

If you find any of the above stated damage. The bearings should be replaced not adjusted. To service the wheel bearings, you'll need to repack the bearings and replace the grease seal.

if you have a semi-floating axle ie an axle that the axle bearing is pressed on you have to remove the wheel, remove caliper if disc brakes and remove a retaining plate that holds the axle bearing in position. pull out the axle and the seal will be left in the axle housing. Replace and reverse procedures. If you have a full floating axle you have to remove the axle from the hub undo tha axle bearing nuts amnd if disc remove caliper or if drum pull the hub of the axle. The seal will be in the back of the hub as in a truck. you will need some mechanical knowledge so if you are unsure get a mechanic to advise you

not sure if this helps or not

It sounds like you may have much more damage than just the tire. My guess is you have bent the axle, so I suggest not driving it, as you can have damaged structural integrity. Tow it.

There should be a vent line and they are also on the F150 Series too. On the F150 and probably your F250 series the vent pipe goes through a rear Brake hose as Ford used the vent pipe to mount and secure the rear main Brake hose. The feeder lines go to each rear wheel.

The vent pipe allows the oil to flow through the ends of the axle shafts more easily and to eliminate any pressure from heat in the Differential. The vent hose keeps water from entering the axle by moving the opening higher in the frame. There is a threaded hole on the axle.

If your vehicle was built with larger rims (Fire truck?) there may be a vent button on the axle at that position. It would be a fitting with a small dome button if Ford felt the truck was high enough off the ground that water was not a problem.

THE AXLE HAS TO COME OUT OF SPINDLE USE A PRY BAR BEHIND THE AXLE AND PRY IT OUT OF THE SPINDLE IF THIS IS A VACCUM OPERATED SPINDLE THE SEAL WILL (HAS TO ) COME OUT

According to AutoZone, if you have the full floating axles they have to come off to get the drum off. The semi-floating axles are easier--if you have those you just need to back off the adjuster as I explained. Reach a thin screwdriver into the hole in the back above the axle. It might have a cap over it or a "punch out." You need to turn the star (slightly visible in attached pic) in I think the up direction several turns to get past the lip in the drum. It will resist turning as it ratchets in the opposite direction. You should be able to tell if you're going the right direction as the drum should get looser.




Removal & Installation

Full Floating Axles
To remove the drums from full floating rear axles, the axle shaft will have to be removed. Full-floating rear axles can be identified by a bearing housing that protrudes through the center of the wheel.

1. Remove or disconnect the following:
   
   Wheel Axle shaft Retaining ring, key and adjusting nut Hub and drum
   

To install:

1. Install or connect the following:
   
   Hub and drum to the tube Adjusting nut Key and retaining ring Axle shaft and wheel
   

Semi-Floating Axles

1. Raise and support the vehicle safely.
2. Mark the relationship of the wheel to the hub and remove the wheel.
3. Mark the relationship of the drum to the hub and pull the drum from the brake assembly. If the brake drums have been scored from worn linings, the brake adjuster must be backed off so the brake shoes will retract from the drum. The adjuster can be backed off by inserting a brake adjusting tool through the access hole provided. In some cases the access hole is provided in the brake drum. A metal cover plate is over the hole. This may be removed by using a hammer and chisel.

To install:

1. Align the mark on the drum to mark on hub and install drum
2. Align the mark on the wheel to mark on drum and install wheel
3. Adjust brake lining as needed. Pump brakes

hub is on the axle shaft so the center cover will have to be removed to remove the c ring that keeps it in place. then remove the axle shaft having the wheel and drum off first
