IRS Grease

[wantscobra]

A while back, I saw a thread about using silicone or lithium grease for the suspension to avoid issues with the polyurethane bushings.

Last year I built up the rear IRS suspension components, and greased them with what I had on hand at the time, before reading that thread. I'm pretty sure the grease used is a red heavy wheel bearing grease.

1. Should I take these apart (they aren't on the car yet) and clean them out and get some silicone grease?
2. Should I be worried about damage to the bushings if they haven't had any load or usage yet?
3. Am I over thinking this too?

Yes I think that would be wise. !00% necessary, not sure. Polyurethane bushings usually come with silicone grease packets, and that is the only thing recommended.

I used that same red grease on my MK4 build from 2018. No issues that I can see so far...

Maybe your grease was/is a synthetic grease. I use a red synthetic because I 'think' that has the least chance of chemically attacking various bushing materials. I also like that all greases seem to turn black when used so I pump the grease gun until the squeeze out stuff goes from black to red.
