I have a 3500lb single axle utility trailer and am going to replace the bearings because I have one wheel covered in grease. Trailer is only a year old and only hauled a 60" eXmark mower. Can anyone recommend a good brand bearing and good grease. This trailer is only a year old and I assumed after this break down that they used cheapest parts available for mass production. I dont want to go that route again. The bearing numbers are L44649 and L68149 using a double lip seal. Thanks in advance
