Kenmore commercial washer making grinding noise
This assumes that you have a basic Kenmore / Whirlpool top load, direct drive, neutral drain (it doesn't spin until the pump removes most of the water) machine.
First, see the Sears parts site for your washer:
Also see the Whirlpool / Kenmore service manual for top load direct drive washers.
See the following for how to remove the cabinet, pump, motor and transmission. YOU DON'T HAVE TO REMOVE THE AGITATORS OR TUB.
I had the same problem with major gear grinding during the spin cycle and this solved it.
Within the transmission are a set of plastic cams that raise the agitator gear when moving into the spin cycle. If the cams are worn, the gear won't lift high enough (about 1/18") and the gears will grind.
Assuming that you know how to remove the cabinet, agitator (you don't need to remove the tub), pump, motor and transmission the agitator cam and follower use the same whirlpool part number 62580/01. This is a plastic set used to raise the agitate gear on the shaft.

Pull the transmission.
Remove the clutch (the spring holding the clutch to the spin pinion is a bear to replace.
Remove the 8 transmission screws carefully, the transmission is full (15 oz.) of 80-90 weight oil.
Remove the transmission cover.
Pull off the spin pinion.
Push down on the agitate spring and remove the spring clip. Note where is attaches to the main shaft.
The two plastic agitate cam parts pull right off. Don't lose the washer on top of the cams.
Replace the cams, washer, spring and clip, pinion, oil (assuming you drained the oil first), cover and clutch parts.
Line up the transmission so that the release cam on the brake drum will snap onto the clutch spring retaining clip and put all parts back in the washer.
The basic tools are screwdriver, small socket set with up to a 1/2" socket, vice grips or good pliers (to remove and replace clips)
Be sure to align the holes on the Motor Coupler correctly or the motor and transmission won't fit together correctly.
Following is also the Whirlpool parts list for their commercial top load direct drive washers that has a better description of the cams.
It is a bit of a messy job but much ($10 vs $170 for a transmission) less than having a service person replace the transmission.
Be sure to study the Service manual so that you can see exactly how the cams work.
While you've got the motor and transmission out, you should check the Motor couplers for wear.
