I would definitely replace the rear main seal - once you remove the seal you will be able to determine if water leaked into the bearings - there will be rust residue or brown film on the front and or rear bearings if seal leaked. Take you finger and spin the bearing and feel for any drag or noise - if no noise or visual rust or water more than likely you bearings are fine and you dodged a bullet. Then just replace the spider and rear main seal - I seat them with glue and press them in place then run a bead of glue around the outside of the seal where it meets the plastic housing as a added barrier. I would also scrub the outer tub pieces front and rear and remove the rubber hoses at the bottom of tub and wash them out individually then replace exactly as they are removed (they can hold coins/underwire bra stays/metal piece of the broken spider etc. and scum) I typically remove all the hoses at bottom and blast with a high pressure water hose and disinfect with bleach! Any problems feel free to DM me I'll be more than happy to help!
Thanks Blaiser for the offer! Would you happen to have the part# of the 6 bolts that secures the spider to the drum? I'm close to sourcing all the parts to do all of this, including the bearings, it will come up to over $375 CAD + tax!
My wife said that it's not worth it to fix a 13 yr old machine (possibility of other parts breaking later) when a new LG WM3700HVA is only around $700 + tax now with the gov't energy rebate. But I wonder how durable these newer models are?
