Bearings, grease zerts
3 of the 4 zerts took grease fine, pushing out old grease and replacing with new. The 4th zert however, Struggled taking grease. I could barely squeeze the grease gun, a lot of resistance. I was able to get some new grease in and some old grease out before my hand went numb, but I don't think all of the old grease. I noticed the zert was a little loose. I also noticed when I first looked at zert, the old grease around zert seemed drier, just different than the other 3 zerts. Any ideas? Is it likely the bearings are bad? Where can I purchase bearings, seals for this Roo? Leaving on trip next Thursday. Thanks.
