Sue, I had mine done at 118K miles. I won't get it done again til 250K. Many who have changed it around 100K have said it still looked new! You could possibly take off one of the covers and try to see what condition it appears to be in.

OK, great, I just crossed this one of my 2010 "to do" list as I only put on about 4k a year....looks like it may be time in, oh, I don't know, let's say closer to 2020!
Thanks again!
