Is it also possible or likely that a shop added some shitty grease to the joints and fucked up the good grease? I think 4WP may have greased them when they did my regear even though I didn't ask them too. This is what the rear uppers looked like when disassembled. The grease is very dry and clumpy. I turned/hidden the zerk fittings upward or inward into their respective mounting brackets in an effort to make them inaccessible to prevent that very thing. I know if I do my own work I don't have to worry about another shop fucking up my shit, but there are a few things I don't have time to do. With that said i do most of my own work.Entirely possible with that grease.
