I've got a 2005 eiger and i'm starting to hear a squeak in the front end. I think it might be a ujoint. Last year the back one went out and when I replaced it with a new one it had a grease fitting (zerk) on one of the end caps. I was thinking of drilling a small hole in the end cap on the ujoins on the front and installing a zerk so I could put some grease in there. Has anyone tried it, or do you know of another way of doing it without taking them out? Thanks for any advise. Jeff
