Default Grease for poly bushings?

VB&P sway bars and bushings. They did not include any but said they would send some. Should it not make it for the weekend what to use?

I've seen some people substitute marine grease. I recommend installing zerks and lubing them with just about anything, regularly.

I used a silicone based grease on my poly-graphite bushings and narry a squeak. You might verify with VB&P.

I've used that too. I've used several different kinds! Usually I use the Redline grease that's in my gun. The problem is none of it stays there long. I can feel the ride get a little harder as the grease goes away and the sway bar becomes a dampener. This isn't good for handling or ride quality and it's why I recommend zerks.

Summit and other places carry the thick bushing lube, there may be a local place that has it. I think what I have out in the shop is Prothane branded.

I agree with the zerks. I installed them on the rear suspension points of my 86 some years ago. I used synthetic grease in my grease gun; Redline's GOOD too.

OK I will be the idiot what is marine grease and where do you get it? Second the zerks do you just drill and tap the bracket and drill the bushing to get grease in? Do you need to put a groove in the bushing?

My local "AutoZone" parts store carries Energy Suspension brand of polyurethane lube made just for the poly bushings. Comes in a yellow blister pack with I think 3 of those small tubes inside. The small tubes you cut the end off and squeeze out the grease.

This stuff is real "sticky", and stays put. Doesn't wash away with rain.

So check your local auto parts store for the right stuff first.
