i dont really understand how the nutsert works and how u keep it from spinning when the new one is installed...i also dont understand how the new one is installed..i got myself all confused.
The nut and the star lock washer prevent the nutsert from spinning. You hold the wrench steady and tighten the bolt. The wrench and nut stay stationary. As you tighten the bolt it creates force on the nut and the lock washer. That force allows the lock washer to dig into the nutsert, holding it stationary. By holding the nut steady it holds the nutsert steady. The nut, lock washer and nutsert act as one moving part and the bolt is the other. The two upper washers work sort of like a bearing between the two seperate parts of the tool.
The nutsert works like this, As you tighten the bolt it forces the nutsert to collapse and expand onto the inside of the frame. Once it is collapsed it looks just like a rivet . The middle of the nutsert is bulged, making it bigger than the hole it went through.
My '06 Parts List does show that part number for the nut inserts (rivets) for the "Skid Plate Support"
6506 629AA Rivet

ok, got a part number from a dealer in another town,
All it said for 99 TJ was - skid plate nut - #6035739
quantity used 6 - $7.50 a piece
Can someone verify this?
AWESOME!!! I think this is it. I have the factory parts printout. This part is NOT shown on the illustration but is listed. It says just what you said "06035739, 6 required, NUT Skid Plate". This must be the early model 1/2" nutsert!
well attempt at resurrecting spinning nutzert failed miserably.
Bolt comes out easily but will not tighten.
I just lock tighted the heck out of it and the other 5 tight bolts and will call it good till I get back from my trip to colorado.
I'm leaving next weekend and driving, so I'll just keep a socket handy and check them every morning.
I'm going to go ahead and order 3 from the dealer and fix it when i get back.
