I have a problem with your greasable bolts for the HD front shackles. The grease zerks came out of BOTH top bolts, the ones in the shackle not the leaf eye. It looks like they are a press in and not a thread in type, so I gingerly tapped them back i but it makes me wonder if they'll vibrate out! I really don't expect you guys to replace them since they have been on the truck for a while, but can you recommend something to help them stay in? I thought a dab of JB Weld, but I don;t want to clog up the lumen of the bore. TIA -- Mike BTW, they came out when I put the grease gun fitting on them. When I pulled the fitting off, the zerk came with it, The lower ones didn't do that. <font color=blue> The mud's on it to hide that it's more than one color.
