Product review (3 stars): Update/ Oct 2016: the replacement spider (along with the other nec. parts) cont. to wrk. Machine operates as it did new
The original part - as has been stated by many - is fatally flawed due to the composition of the metal that is not consistent with durability and reliability.  I have attached a photo of the original part to drive home the point.  It is a legitimate question of whether the LG company has purposely used this part to inspire new purchases of entirely new machines, as most people will reasonably be frightened by smoking machines that smell of burning rubber and bothered by a repair bill that in effect- makes purchase of another machine a more reasonable option.
I installed the part a month ago, and so far the machine is running as it did - when new. it is original OEM and fits (assuming your drum is not ruined from the failed original spider part).
