Review on XiKe 171255TB Trailer Grease Spindles by Alex Tinker

2.125" ID x 3.376" OD Trailer Hub Grease Seals Every spring and fall we make a 5,500 mile trip from Lower Alabama to Montana and back (with trips to our favorite overlooks). During the ride I remove the hubs, inspect the bearings, lubricate and replace the seals. I have used three sets of these seals so far and have had no complaints. It is a double spring loaded seal (metal to metal contact area) which seems to work well. I always put some wheel grease on the rubber part of the seal. This prevents the dry rubber from touching the metal when the wheel starts to roll. This for 49 years and not a single mistake. It's a good deal for the money. I would recommend these seals. Just make sure YOU order the right size! Much luck!
