Being lazy is going to cost me. I've owned my car trailer for 9 years now and it might get used 4-6 times a year but sometimes its a pretty long trip. It seem like forever I have been telling myself to pull it apart and pack and adjust the bearings but there was always something better to do. Well today I finally had a nice day and got out there to do it. When I jacked it up and could move the wheels over 1/2" on the hub I got a sick feeling. Well luckily I never had a failure but the inner bearing had started eating into the shoulder of the hub creating more clearance and adding freeplay. I will now have to buy two axles at 100.00 ea before I can feel like my trailer is safe to use again.
