Yes. Depending on what year you have. Mine's a 99 and I think they started this in 98. If you're talking about the black lateral step trim sliding down the gray piece, this is what to do:
1. Remove the black button on the rear edge of the black piece
2. Pull it up and away an inch and you should see small teeth on the inside of the black piece and outside of the gray one.
3. Realign the black trim by pulling it up to level and interlock the teeth.
4. Go to Napa or wherever and buy two black plastic retainers like the ones you removed and insert them in the holes to lock the black piece in place.
For some reason, the older trucks don't have the "adjustment" feature and you can tell cause the bumpers sagging away from the fender which looks terrible. It seems the gray piece is the one that sags, but I couldn't figure out how since it is secure. But by raising the black trim back to level, it improves the fit. I hope this works for you. It's super simple. Good luck.
