Top lock cap (1990-02)
Product Review (submitted on January 22, 2016):
I checked my top lock caps and found that maybe 1/3 of the plastic still existed. I believe that was causing a lot of the vibrations and squeaking near the latches. I installed a pair of these in under 10 minutes total and went for a drive. The latch noises stopped entirely because now there was a full nub of plastic in there to make a tighter fit. Totally worth the $4 each for these basic maintenance items.
