I had the bearings in my Rogue toe arms replaced with Aurora spherical bearings at VAC Motorsports (they recommended and did all the research for me). Top quality. VAC put real rod end boots on them that cover the entire end snugly as well, as opposed to the practically worthless ones that came with these. I should be good for a long time.
