Using a fifth wheel lube plate question

What's wrong with it being shiny? A pic of your top plate would help. Yes, you need the mating surfaces clear of any grease.

 

Works for me. You can make it work for you.

WD-40 and PB Blaster are also good in a pinch.

 

I’ve always used the same grease the rest of the truck gets.

 

It doesn't matter. Grease doesn't hurt anything. Plate and hitch being shiny is from rotation during turning.

 

If you’re running a disc and your 5th wheel gets shiny that’s fine. It’s also doesn’t matter if there’s a little grease on it either. I run a no lube top plate on my 5th wheel and we drop and hook a lot, so I always end up with grease on the Teflon pads. The main thing is if you do get grease on it make sure the grease doesn’t have any rocks or grit mixed in with it, that’s what will ruin your Teflon plate.
