94 Mazda B4000 4x4 5spd AutoHubs Dana35.

High ya;
Now I realize that the locking hubs suck and should be replaced. When I got the spare change I'll do just that. DynoMax, K&N, tires and stuff like that coming first.

How do I fix the freaking front wheel drive? The locking hub components are NOT broken or worn. The transfer (electric) positively engages the front drive shaft. The drive axles engage and turn. I can stop them with my hand when the hubs are removed. But the front wheels don't turn when I put all 4 in the air, start it up, put it in first, and engage the 4x. Both rears turn. Front drive shaft turns. Front axle turns. Not wheels. How do I get the hubs abart? I mean the center that comes off after the tire comes off. Got a little snap ring in the center. I can take that out, but nuthing else wants to fall apart.

 

Not real sure on the exact tear down without the book in front of me. (Good idea to spend the $20 on one) Sounds like maybe you need to clean and re-lub them. My '96 Ranger had that problem. I used a light weight lube on them and very little of it. Vaseline will actually work but a light weight lithium grease is better. Once lubed, use them once a month to keep working good. ($200 for manual hubs)

I have a Haynes book. It don't show or tell how to take apart the hubs themselves.

 

See if you can get a Chilton repair manual (maybe from the local library). If not, check out helminc.com. They have owners and shop manuals available, decent price.

Remove the snap ring from the end of the shaft of the front wheel spindle .
Remove the axle shaft spacer.




CAUTION: Do not pry on the cam or thrust spacers during removal. Prying may damage the cam or spacers.

Pull cam assembly off the wheel bearing adjusting nut and remove the two metal thrust spacers from the adjusting nut.




NOTE: If required, rotate the adjusting nut slightly to relieve pressure against the locking key, before the key can be removed.

CAUTION: To prevent damage to the threads of the front wheel spindle , look into the keyway of the front wheel spindle under the adjusting nut and remove the separate locking key before removing the adjusting nut.

Using a magnet, remove the locking key.
Loosen the wheel bearing adjusting nut from the front wheel spindle using a Hex Locknut Wrench T70T-4252-B.
While rotating the hub and rotor assembly, tighten the wheel bearing adjusting nut to 47 Nm (35 lb-ft) to seat the wheel bearings. Spin the rotor and back off the nut one-quarter turn (90 degrees).

WARNING: EXTREME CARE MUST BE TAKEN WHEN ALIGNING THE NUT OF THE FRONT WHEEL SPINDLE ADJUSTMENT LUG WITH THE CENTER OF THE KEYWAY SLOT OF THE FRONT WHEEL SPINDLE TO PREVENT DAMAGE TO THE SEPARATE LOCKING KEY. THE WHEEL AND TIRE ASSEMBLY MAY COME OFF WHILE THE VEHICLE IS IN MOTION IF THE KEY IS DAMAGED.

Align the closest lug in the wheel bearing adjustment nut with the center of the keyway slot of the front wheel spindle . Advance the nut to the next lug if required. Install the separate locking key in the keyway of the front wheel spindle under the adjusting nut.
CAUTION: Extreme care must be taken when aligning the fixed cam key with the keyway of the front wheel spindle to prevent damage to the fixed cam.

Install the two thrust spacers and push or press the cam assembly onto the locknut by lining up the key in the fixed cam with the keyway of the front wheel spindle .




Install the axle shaft spacer.
Clip the snap ring onto the end of the shaft of the front wheel spindle .
Install the automatic locking hub assembly over the front wheel spindle . Align three hub assembly legs with three pockets in cam assembly. Install the retainer washers.




Install the wheel and tire assembly. Install and tighten lug nuts to 135 Nm (100 lb-ft).

 

Ken; much thanks dude, but that is the easy part. What I'm looking to take apart is the locking hub itself. Say you take off the tire/wheel assembly, then the next part to come off it the black center hub. THAT is what I want to take apart. It's got a little bitty snap ring in the center. I took that out but still couldn't get anything out of it. Want to try and clean it up and make sure nothings broken in there.

 

Again from the same, is this what you need, I'm not into 4wd.

The recommended wheel bearing lubricant is lithium-base High-Temperature Constant Velocity Joint Grease E43Z-19590-A or equivalent meeting Ford specification ESP-M1C207-A.

CAUTION: Sodium-base grease is not compatible with lithium-base grease. Do not intermix. Clean all old lubricant grease prior to lubricating front/rear wheel bearing. Use of incompatible bearing lubricant could result in premature lubricant breakdown.

NOTE: If bearing adjustment does not eliminate looseness or rough and noisy operation, clean, inspect and repack the hub and wheel bearings with specified wheel grease. If wheel bearing cup or the cone and roller assemblies are worn or damaged, they should be replaced.

I appreciate your efforts, but no. The part may be called something else. It actually slides onto the spindle, and is the last thing put on before the wheel assy.

 

Sorry, I can't find anything else that fits.

Can anyone with 4wd knowledge help on this one?
