Replaced it last year. The grease zerk on the bottom faces straight down and close enough to the frame that you can't get a grease gun to fit in there. I'd like to replace the zerk with a 90 degree one (was there a 90 on there from the factory?) but I can't find the right size locally. I'm wondering if the aftermarket replacement is some kind of oddball thread size for the zerk. The threaded portion seems wider than the other grease zerks on the car. Anyone know what size is on there and where I could get one. Maybe the original idler I replaced had so much play in it because no one could get grease in there?
