Blew out cush drives 2012 M1100 EVO - Question on installing new

[EEL]

So I just received my superlite cush drives and carrier. Whats the process of installing these things into a carrier. They seem to be a very tight squeeze. Am I supposed to grease them? They are made of rubber but rather some poly urethane compound.

I dont want to press too hard and break something. (Yes they are the right size)

Open to insight from those who have done this before.

Polyurethane-compatible lubricant, and push 'em in.

I think I'll get some silicone spray.
