Is there any way to repair the latch on the cupholder door?

The cupholder door won't latch.  OK.  Correction, it won't latch until I try is 50 times until I get lucky.  This happened a year or two ago and I found a forum that instructed me how to remove the cupholder assembly and clean out the old grease in the latch mechanism and that solved the problem for a while.  It have a feeling the white nylon catch is worn out.  Is there any known fix for this condition or am I stuck buying a new assembly for $400+?
