I appreciate that explanation. Ty. I guess I should’ve added, though, how is it different from OEM? I watch a channel called Savage Geese on YouTube where as part of their reviews they always stand under the vehicle on a lift and go over the suspension, etc. and it looks pretty much the same as far as uniballs and where each piece connects. Of course I’m probably wrong. If I am, and the OEM parts are somehow protected, doesn’t seem that tough for the aftermarket to do the same? Is it the covers that @Zeusmotorworks shows above?Pretty much all aftermarket suspension and these things use FK uniballs or rod ends. So you’re not mistaken because they are exactly like other suspension parts out there. FK uniballs and rod ends require constant lubrication and are extremely susceptible to corrosion and wear caused my grit. I live in Washington and go up and down the passes often in the winter. FK stuff lasts about a year doing that before there’s enough wear that replacing it would make sense. Of course I let it go for 2-3 years and put up with the noise and play. I will not touch any “upgrade” with a 10’ pole if it has FK uniballs or rod unless it’s so good that I think it’s worth pulling the part and replacing the things every year. People located in dry areas will not have any of those issues.
