I have a 2002 Big Bear, and I put a drop rack on it. I have a problem with it sagging terribly. I tighten the stock rack as much as I can, but it just does not seem to hold. Short of welding it, does anyone have any ideas on keeping it tight?

The Big Bear has such a soft suspension that it is going to sag some anyway. I have tightened it as much as it will go, but it is still pretty soft, and I have a lift kit on it as well.

 

The bolts on the OEM rack is backing out or the bolts on the drop rack is backing out?

 

It is the bolts on the OEM rack that are slipping.

 

Can you put a back up nuts on the bolt. You know on the threads that are sticking out (If there is some).
