the washer makes a loud thumping noise during final draining cycle (last 10 minutes). Sounds like it is out of balance
Is this a good question?

First thing would be, is it out of balance? Does it do this all the time or with different types of loads?
Tub Bearing
If the washer is making a loud noise the tub bearing might need to be replace. This is a very involved repair and will require disassembling most of the washer. The manufacturer recommends that if possible the complete outer tub and bearing be replaced rather than attempting to replace just the bearing in the tub. If the bearing is bad the problem is going to get worse very quickly and so either the drum and bearing will need to be replaced or the washing machine.
Tub Seal and Bearing Kit
If the washer is making loud noise the tub seal and bearing kit might need to be replace. This is a very involved repair and will require disassembling most of the washer. If the bearing is bad the problem is going to get worse very quickly and so either the tub seal and bearing kit will need to be replaced or the washing machine.
Rear Drum with Bearing
If the washer is making a loud noise the rear drum with bearing might need to be replace. On this washer the bearing might not be sold separately, the entire rear drum might have to be replaced. This is a very involved repair and will require disassembling most of the washer. However, the problem is going to get worse very quickly and so either the drum and bearing will need to be replaced or the washing machine.

Drive Pulley
If the washer is making a loud noise the drive pulley might be worn out, cracked, loose or bent. Remove the drive pulley and inspect it carefully. If it is damaged or defective replace it.
Pulley
If the washer is making a loud noise the drive pulley may be worn out. If the drive pulley is loose or wobbling it will need to be replaced
U-Joint Kit
If the washer is making a loud noise the U-Joint may have failed. This is the primary drive mechanism for the agitation motion in this washer. Although this is not a very difficult repair for a DIY'er with some experience, the part is expensive and so it may be worth considering a new washer.
Motor Coupling
If the washer is making a loud noise the motor coupling might have failed. The motor coupling connects the motor to the washer transmission. It is designed to fail if the washer is overloaded in order to protect both the motor and transmission.
Clutch
If the washer is making a loud noise in the spin cycle, the clutch assembly might be worn out. The clutch assembly makes the connection between the transmission and the inner tub. It is designed to allow the tub to get up to the proper spin speed gradually. As the clutch wears out it may become loud during spin or just after the spin cycle finishes. The clutch is not repairable, if it is loud or not working properly it will need to be replaced.
Drive Belt
If the washer is making a loud noise the drive belt might be defective. Over time the drive belt will dry out and start cracking, eventually a piece of the belt can break off resulting in a loud noise whenever the motor is running.
Transmission
If the washer is making a loud noise the transmission might be worn out or defective. There are many other more likely causes for noise from a washer. If the noise turns out to be caused by the transmission it may have to be replaced.
Drain Pump
If the washer is making a loud noise the drain pump might be going bad or might have something caught in it. Remove the drain pump from the washer and inspect it carefully. Look for anything that might be caught in it, a piece of wire, plastic, etc. If nothing is wrong with the pump, but it's still noisy it will have to be replaced.
Drive Motor
If the washer is making a loud noise the drive motor bearings may have worn out. Washer motors are normally almost silent when they run. If the motor is run without a belt hooked up to it and it's loud it will have to be replaced.
Water Inlet Valve
If the washer is noisy or loud, particularly when the washer is filling, the water inlet valve may be at fault. The noise can be caused by a restriction in the valve from mineral deposits. If it is the water inlet valve that's loud during the fill cycle it will need to be replaced. It is not safe to take apart these valves as they can fail and flood after disassembly.

This is the opposite of helpful.
wilber, you are more than welcome to post your own answer. the question is like going to the doctor and saying I hurt and expecting a solution without giving any more information. I just listed everything that could be the cause. What would YOU like changed?
Please tell how you recommend deciding which symptoms indicate which problem needs to be addressed
William Diagnosing the problem is half the job on anything from a washer, computer or the human body. You have to look at the symptoms in each particular case and eliminate what could be wrong. These can be anythings from diagnostic lights, codes, smells or sounds. Run tests, a multimeter is your friend, use it, test.
"when you have eliminated the impossible, whatever remains, however improbable, must be the truth" Sherlock Holmes
I have removed the front panel and run the spin cycle .
The motor jumps back and forth with each drum rotation there is a faint burning smell occasionally. What do you recommend I check next and how do you recommend checking for it?
I service gas logs and the first thing they taught was not to just swap parts but to follow a diagnostic thread in order based on the symptoms , Unfortunately I could use a little guidance of what to look foe next and how to do it.
Thanks

Hi Ron, did you ever identify the problem? I am having the same issue and don't know where I'm going to start... The thumping/knocking/whatever you want to call it occurs when the washer is spinning fast during the drain cycle. Any info is greatly appreciated. Thanks.
