Tub makes loud thumping noise when spinning

If it's a roaring noise, the tub bearing is probably wearing out. Spin the tub a little with your hand, if you hear a little of the roar, that's it.

Hi,

When my washer did that, I found that the shocks that hold the tub were bad...

Check out this tip I wrote about the noise and vibration that front load washers can make..

Washer Problems Washer noise when spinning

if it's making a noise then either your drain pump bearing is going out or your thrust bearing is going out (assuming the noise happens in both spin and wash). Tip the washer backwards so that you can get underneath of it. Take the belt off and spin the pump pulley on the right side. This should spin effortlessly.

The middle pulley is the trustbearing pulley. Spin this--- one direction it should have a little bit of resistance--- the other should have more resistance

Need more information to make an accurate diagnosis, try removing the front panel (two screws at bottom) and visually check first the belt (all the way around) and then the springs that hold the tub suspended.
I would bet on the belt.

support bracket that supports the tub is breaking. stick your hand inside and push up and down and see if its coming apart. if u look at it when it runs does it wobble?(the tub) if not take a look at the pulley on the back and see if its wobbly.

My guess is that one of the three counterweights have separated from their support. Probably rusted away.
36 years is quite a feat. Today's machines would be lucky to 1/3 of that life.
Sounds like its time to go shopping.
Do you have an anniversary coming up?
Ladies love washers for an anniversary gift.

when it is in high spin then you stop the washer it makes a thumping noise until the basket stops sort of like a flat tire sounds to me like you need a drive block

check the bearing.

Chances are it is not the tub. It is probably the transmission. It has been my experience that the transmission bearing starts to make noise. Look under the unit to see if you can spot any transmission oil. If there is oil, it's time to start shopping for a new unit.

check and make sure the washer is LEVEL otherwise when in spin, it may "walk" across the floor. also if it's not level then the tub will "tilt" in one direction and may contribute to the thump, thump.
