Upper control arm joints
I was greasing the front suspension on my 2004 FX4 II and noticed that there is a small hole in the rubber boot on the driver's side upper control arm and the grease was coming out. I checked the other side and it looks like a previous owner replaced the upper control arm on that side and there isn't even a grease fitting on the top. The boot on that side looks good though.
Is it a problem if the boot is leaking a bit on the driver's side? Is it worth the trouble to replace it?
