Our Samsung front loader has been a great trouble-free washer but as of lately it has been becoming progressively louder during the spin cycle. After reading a few articles and posts on the web, I determined it was the spider arm assembly.
I ordered the new assembly, rear tub seal and main tub seal (the seals were ok but it was a good time to replace them as well) from appliancepartspros.com. Watching the video repair on their site was a great help and readied me for the repair. The parts shipped the same day and were delivered the second day.
The disassembly, repair, and reassembly went perfect.
We ran a "test" load of laundry and the washer performed like the day we purchased it.
I'll definitely use appliancepartspros.com for my future appliance parts needs.
