A GE dryer rear drum bearing came off while the owner was cleaning the machine, and it could not be screwed back on from outside. On a GTD42EASJ2WW the bearing seats against the back of the drum, so the fix was to strip the dryer down, fit the bearing to the drum, and rebuild the cabinet around it.
What I found and how I put it back together
The machine was already open when I arrived. The owner had pulled the back panel to clean the inside, unscrewed the rear bearing, and then had nothing to line it up against once the drum had shifted. Working from behind the cabinet, there is no way to get the bearing back where it belongs, which is why the job stalled. I took the dryer down far enough to free the drum, mounted the bearing on the drum first, and reassembled the machine in that order. The unit was a GE GTD42EASJ2WW in a home in Tustin.
Why does a GE dryer rear drum bearing need the whole machine apart?
Because the bearing is part of the drum assembly, not part of the back panel. The rear of the drum rides on a center bearing that sits in a socket on the rear bulkhead, while the front edge is carried on rollers or glides. The fasteners are reachable from behind, so it looks like a part you can remove and refit through the back opening. Taking it off is easy. Putting it back means the drum has to come out so the bearing can be seated on it squarely, then the drum goes in and the bulkhead closes over it.
A worn rear bearing usually announces itself before it fails outright: a grinding or rumbling that rises with drum speed, and sometimes a drum that sags toward the back. Noise from a dryer does not always come from the bearing. I have traced the same complaint to a clogged vent and a loaded blower wheel on another machine, and worn front glides make a similar sound.
What can you check yourself?
Unplug the dryer first, then open the door and turn the drum by hand. A smooth drum that spins freely and quietly points away from the bearing. Grinding, catching, or a drum you can rock up and down at the back points toward it. Pull the lint screen and clear the housing, and check the vent run behind the machine for a crushed or packed duct, since a blocked vent makes its own noise and costs nothing to fix.
Past the back panel, leave it to me. Once the panel is off, the belt, the blower and the drum supports all have to come apart in a set order, and reversing that order with the drum unsupported is how parts get bent. On the house side, a receptacle that shows damage or a breaker that trips again after a reset is work for an electrician, not an appliance repair.
FAQ
Why is my GE dryer making a grinding noise from the back?
The usual suspects are the rear drum bearing, the front drum glides, or something lodged in the blower wheel. Coins and buttons that slip past the lint screen end up in the blower housing and make a hard rattle that comes and goes with the motor. A bearing noise is steadier and deeper, and it usually gets worse with a heavy load because the extra weight presses the drum into the worn surface.
How long does a dryer drum bearing last?
Most of them last the life of the machine. What shortens that is heat and load: running with a restricted vent raises cabinet temperature and dries out the bearing surface, and consistently overloading the drum puts side pressure on it. If a dryer has been run noisy for months, the bearing socket in the bulkhead can wear too, and then the bulkhead goes in with the bearing.
Is it worth replacing a drum bearing or should I buy a new dryer?
The bearing itself is an inexpensive part, so the decision is about labor, since most of the work is disassembly and reassembly. If the cabinet is solid, the motor is quiet and the dryer still heats properly, replacing the bearing is the cheaper path by a wide margin. If the motor is also growling or the drum seam has split, those repairs stack up and a replacement machine starts to make sense.
