Yeah. Get some suspension grease on your finger and slide other the truck. Pull back the isolator and work the grease on the shaft of the shock with your hand as high up as you can till you hit the bottom of the bump stop. Then, grab the bump stop and pull it up and down the shaft of the shock until it slides with ease.
You'll be good to go after that.
You need grease like this, or similar

Pretty much the type of grease that goes in Zerk fittings.
