fitting on 1500 UCA?

[sgh1500]

Any ideas on what this fitting is on my UCA, looks like grease fitting but location is odd, there in not one on rear side of the UCA, and it is larger (13mm dia) than standard grease fitting. I have 4x4 offroad package so suspension was upgraded from factory.

Thanks

Those are for the links that are used with Air Ride suspension. It moves an actuator up or down to tell the vehicle what position the suspension is in. Sense you have coils. You can disregard these nubs.
