I have a 1994 GMC K1500 Sierra :5.7L 350CI V8 and I have a worn front wheel bearing and I took the hub off and saw that the inner bearing is in peices, Now I cant find where to find the bearing,, All I can find is the the hub bearing assembely. Why cant I just get the bearing and not the whole hub?

back then it was paper, book, not digital then
but lean scans shown here.

By any chance have you jacked up the front of the truck and set it on jack stands. And engage your 4x4 and see if your wheels turn at all. You might have a hub problem they might not be engaging on your front axle.

FRONT END SHIMMY AND SHAKING COULD HAVE A TIRE OUT OF BALANCELOOSE OR WORN WHEEL BEARINGS, WORN OUT BALL JOINTS,WORN OUT TIE ROD ENDS, FRONT END NEED ALIGNMENT.BRAKE ROTOR WORN OUT OR WARPED, MANY THINGS WILL CAUSE FRONT END TO SHAKE SHIMMY.

hub to steering knuckle 133 ft lbs.

axle nut 155 ft lbs.

lug nuts 140 ft lbs.

Sounds like the electrical actuator is bad on the front axle.

Its probably the 4L80E trans. Front seal might be possible. Sounds like torque converter to me. Does it still leak at that speed when the tranny is cold? Or just when its warm?

Hi,
Do you have auto locking hubs on the front wheels, or manual locking hubs?
If you have auto locking hubs chances are they are not engaging properly and will need to be removed and spline sets checked for broken teeth on locking hub and locking shaft.
If you have manual locking hubs then check that they are firm when turning to engage them in the lock position.If they are light when engaging them to the lock position then they my have broken/worn out the locking hub and spline. Also check that the engaging spring inside the hub has enough tension to engage the hubs they may be broken. If the hub are all ok then you have a problem in the transfer box, where the 4WD lever is not meshing the transfer box properly. Hope this helps, let me know how you get on.

have to jack it to have a look first ,its impossible to say as a pad could have worn out and moved jamming it up, a wheel bearing has seized ?? just cant tell till its inspected

sounds like you have a worn wheel bearing which is replaced as a hub assembly the rotor just sits on the hub and wheel hold rotor tight

Knock the wheel studs through the assy.
