Correct way to lubricate the lower trailing arm at the hub carrier of a SPF

I'm working on a friends Superformance Cobra early 2600 series car that had a rear hub bearing fail. Last weekend we removed the hub carrier and he has since had a new bearing installed. We will soon begin to assemble. A few questions. Is there a correct method of lubricating the lower control arm assembly where it attaches to the hub carrier? There is a steel pin or rod that spans end to end of the lower trailing arm and has a bolt on each end and an allen head set screw midpoint of the hub carrier to secure the pin. This steel pin is smaller in diameter in the middle third and there was some grease in this location when the pin was removed. There is also a small hole at each end of the hub carrier where the pin goes through. It would almost appear that the set screw would be removed and a zerk fitting installed temporarily to add grease until the grease comes out of each hole of the hub carrier. If this was the case and you put the set screw in place what would be the need for the lubricant other than an anti-seize purpose? With the set screw in place the pin would rotate within the nylon or poly bushings of the trailing arm as the suspension goes up and down. Without the set screw I could see the hub carrier rotating on the pin. If the set screw is to prevent the pin from coming out should one of the trailing arm outer bolts fall out then my question is how to lubricate if at all the nylon or poly bushing in the trailing arm? It would appear that the lubricant would come off as you install the pin because of the tight tolerances. Should this bushing need lubricant, would you suggest to drill and tap the lower control arm and install a zerk fitting each side to lubricate the bushings? Finally, any issue with torqueing the lower trailing arm to hub carrier bolts with the car on the jacks? I know vehicles with rubber bushings the control arms are torqued while the car is on the ground to prevent preloading the bushing causing premature wear and affect ride height. Thanks in advance.

I had to replace my left rear bearing before an event at VIR. Dennis Olthoff took care of me. Pose your question to him and i suspect you will get your answer.

Thanks. My intent was to call Dennis today but it was a busy busy day. Will try tomorrow.
