If you have a Maytag Performa washer that shakes a lot, or has a weak spin, you probably have a bad snubber.Look for white shavings at the bottom of the washer, this will confirm a bad snubber.If you see a lot of oil at the bottom you have a bad tranny seal, probably new tranny time. A little oil is normal.
To replace this, download the service manual located at (www.appliancejunk.com/forums) Click on manuals, then washers.
Follow the procedure shown, you will need to pull the entire tub out with the tranny, turn upside downand brace with pieces of 2x4's. To save strain on the back, you can pry up the tub from the bottom and slide out the front. Use electrical metal boxes to spread the springs when removing, or use 1/8 inch thick pieces of metal, no need to buy the spring spreader tool. You will NOT need to buy the expensive brake release tool. If there is a spin screech when stopping, you will need to replace the brakes also, But be careful, there is a 200 pound tension spring in there.
Buy six 8-32 machine screws 1 1/2 inch long and replace the brake housing screws with these. Loosen these screws, keeping the housing even, until all the tension is off the assembly. When you replace the snubber, clean the housing with alcohol getting all the oil off. Emery paper the housing if necessary, then insert the new snubber and sprinkle corn starch on it. That will keep the wear down. If the base is pitted/worn too bad, you might want to replace it.
With your model washer, you may not need to buy the screws, the existing screws might be long enough.
Probably a two hour job, good luck.
