How to Troubleshoot & Replace Lg AP4437693 / 4036ER2003A Tub Seal

I followed a couple of Appliance Parts Pros videos that helped me identify the root cause, disassemble the washer, order the parts, how to install the new parts and reassemble. One of the difficult things was getting the replacement door boot gasket clamp back on. It will take two people (four hands) to get it on properly. 

I spun the inner drum by hand and I could hear a low rumbling noise. I was sure it was a bad bearing but I was not sure which one. I looked on line and found the parts I needed at Appliance Parts Pros. I looked at the on line video instructions for replacing both bearings and the tub seal. I ordered the recommended repair parts and the door boot gasket. The door boot did not leak but it looked worn and smelled bad. The on line video instructions were great! I followed the instructions and completed the repair. The only surprise was it took about 3 hours to clean the dirt and scum off the inside of the outer drum. This step was not listed in the instructions but I think it was worth the extra time and now the inside of the washer smells much better. 

I received the parts and they were high quality. I followed the instructional video and replaced 2 ball bearings, seal and tank seal on my LG front loader washer. The video was excellent. It help me step by step in detail with my repair. It took me and my son in law approximately 3 hours to complete the repair. I am very thankful for the innexpensive parts and the detailed video. Thank you appliance pros. 

Based on initial suggestions, replaced shock absorbers(no difference), noticed rubber from front tub and door seal in tub removed top of washer, ran on delicate cycle low spin to observe, tub rubbing on seal. removed seal, front tub cover broken on seal lip, still extremely noisy, out of balance, noise coming from rear area. More research pointed to rear tub support(spider) removed complete tub unit including rotor and stator(quite easy actually) disassembled tub cover, rotor-stator assembly, found spider to be broken into 3 large pieces but still attached to drum by bolts. Replaced front drum cover, Spider(rear drum support), bearings and seal, front tub and door seal(all done on floor with unit removed), re-installed tub unit. Now runs perfectly, quieter than when new. Approx. cost $150 for parts, 4-5 hrs. for repair(could have done in 3) wasn't in any hurry. A little mechanical ability and common sense, makes this an easy repair. Unfortunate that this was not listed as a primary problem to look for in troubleshooting guide with a video to accompany repair. 

The first thing I did was to go to appliance pro.com to view the video on breaking the machine down to see if I could even attempt to make repairs. Then I found the same problems I had by reviewing customer input on appliance pro site. I owe this repair to the video I watched many times during disassembly and then reassembly The part that failed was the spider assembly and the rubber boot from drum rubbing during spin cycle. I ordered both bearings, the rear seal, front boot, new drum o-ring, and the spider assembly. The total time to disassemble was 40 minutes. The reassembly time was just a bit longer. Machine is working like brand new and I saved over 500 to 600 dollars by repairing as oppssed to replacing the machine. Total cost was $202.00 including s/h Thanks to appliance pro it was a stress free repair John 

Before you start the sider replacement make sure the drum is not out of round this can also cause machine to shake also, replaced spider and I recommend changing both bearings and seal at this time regardless if they make noise or not , repair was easy and video helpful 

Ordered parts from appliance parts pro and watched the tutorial to walk me through the process. Could not have done it without it. Everything went great! Thanks 

My best guess was that it was the bearings. And I was right! I followed the instructions on the video from this site. The video was very good, so I didn't really face any real surprises. The job took me about 5 hours. Realistically, I probably spent at least 2 hours of that cleaning the parts. The drums and the main gasket took a fair bit of time to clean; I certainly was not going to put it back together with dirty parts! The other part that took me way longer than the video would indicate, was pounding the inner tub out of the bearing. This problem, of course could be specific to my job only, but after probably about half an hour with a large rubber mallet, I ended up going to a piece of hardwood and my 10 lb sledge hammer. I was worried about damaging other parts using this much force, but in my case it worked out. If I were to do it again, I would get some better rust busting fluid than the WD40 that I used. I would apply the fluid and let it sit for a bit. This would probably make this part of the job go better. Summary would be that if everything went smoothly like in the video I would probably have been able to do it in 2.5 hours (depending on how much cleaning was required). If I had to do it again tomorrow, I bet I could do it in 1.5 hours easy. I'm glad I replaced all tub seal as well, as with that size of job, the extra few bucks was worth the peace of mind that it probably wouldn't leak after putting it all back together. Washer is working great now! 

Our eight year old LG washer had given us great service, but then one day started making a horrendous noise during the spin cycle. I called the appliance repairman and he said it sounded like bearings and he could fix it for $800, but recommended we get a new washer. I found the video here https://www.youtube.com/watch?v=Y-eAvoBI59Y and watched it through. It seemed pretty simple so I ordered the parts from Appliance Parts Pros. I spent a total of about 5 hours pulling the entire washer apart to replace the bearings and although time consuming, the job was not really difficult. I ordered the two bearings, bearing seal, tub seal and spider arm. I ended up returning the spider arm since the existing one was in good shape and I was having trouble removing the old one. All in all, everything ended up costing me about $50. My wife published pictures on Facebook and now all our friends think I am a wizard! 

After watching video provided by Appliance Parts I made a reasonable deduction the tub bearings most likely failed. Since the entire tub required removing I decided to order all associated parts required to rebuild the tub assembly completely. Parts required and ordered included spider assembly , both inner and outer tub bearings including bearing seal and one tub o-ring. Thanks to the video the repair was very simple requiring about 2 hours of repair and two hours for cleaning the washing machine and work area. I would suggest removing the bearings with a long 1/2 inch socket set extension and installing with a properly sized block of wood to hammer the bearings in with. I would just point out glad I ordered the spider assembly because that was the failure mode. Before installing the spider assembly I painted with enamel paint to add additional protection from the bleach and phosphates which I believe destroyed the spider assembly. I would also point out I believe the spider assembly is produced using sintered metal not forged or casted which also added in the failure process. I expect this fix will be numerous for machines produced using this process. Thanks to AP for the very detailed video , made the project simple. Please follow all safety practices regarding electricity and always use personal protective equipment , safety glasses , gloves , etc.
