: what kind of grease to use on Polyurethane bushings? RAMBO Apr 17th, 03, 4:16 PM I'm getting ready to put on my BMR lower arms this weekend- I got the Rubber/Poly combo arms- with the zerk fitting on the poly ends... What kind of grease do you use on the Poly end? Just regular suspension type grease, or is it supposed to be something special? Thanks! Ben Slo307 Apr 17th, 03, 4:23 PM Most poly grease that is supplied with poly is a high pressure silicone or synthetic grease. Aledgedly other greases will soften urethane. RAMBO Apr 17th, 03, 4:48 PM no grease was supplied... BC Apr 17th, 03, 4:59 PM I disagree with slo307 because polyurethane is supposed to be immune to ANY kind of grease or oil. I have gotten into the habit of not using the supplied grease and just using a good synthetic grease and never had a problem. The 'sticky' grease seems to just disappear after a while anyway... Good luck, Bill C. Clint44 Apr 17th, 03, 6:08 PM I used Redline synthetic grease on mine. No squeaks since installation. RAMBO Apr 17th, 03, 6:57 PM How do you apply that stuff to the zerk fittings? Do they have an insert for a grease gun? | ||
