Quick question. I have a CC trailer with ez lube hubs. I replaced the bearings and races last fall. I have a little tick in the one hub. I jacked it up and felt a TINY bit of movement so I snugged the castle nut up. Actually, I released the torque off the nut and then retorqued to 37 ft/lbs and it felt really good. Here is my question though....If I release the torque off the castle nut, I feel like the nut will be too loose. The tang or tab that has to be flipped up on the castle nut is going to cause it to be too loose I think. Is 37-40 ft/lbs of torque too much. I have never had a problem in the past until this one time. What do you guys think??
Thanks for any help. Heading down to Lake of the Ozarks for a week and don't want any surprises on the way down!!!

well never used a torque wrench on a wheel hub before. basicly what you want to do is while spining the hub tighten the nut until it stops while apply a small amount of force, everything should spin freely, check to see if you can insert the cotter pin through the castle nut and hole in the spindle, back it off untill you can if needed.
not sure what you tick is but you should have any at all.

Thanks 79, I think it should be fine but thought I would ask. I sure don't have any clue as to what the ticking is either. You will only get it every once in a while. I only have 100 miles or so on the bearings so they are still seating. As long as there is no wheel movement and plenty of grease, I hope everything will hold together.
When i did the job last fall, I took emery cloth and really shined up the surface where the seal seats and also where the bearings sit on the spindle. I had major problems with the old bearings causing me to clean up the spindle. But after all that was smoothed out, should have taken my center punch and put a few dimples on the spindle to keep the bearing from spinning. I had never had this happen on any of my trailers until my flatbed did it this spring. Old farmer told me to put a few dimples where your bearing will seat onto the spindle. This will keep it from spinning. It has worked well on my flatbed so far.
Thanks again for the advise 79!

well don't thing I would have done any of that and you might have screwed things up depending on how much material you removed. There is no need to worry about the inner races they are suppose to float on tapper rollers as the outer race is press fit and the inner race should be a close toleranced slip fit and as the bearing heats up the innner race sticks to the spindle. Since you have enlarged the clearance between the spindle and inner race it is more likely to spin more now creating more heat and premature bearing failure, and for the dimple hope you got it all on the spindle and nothing on the race as if you did then you have done a major no no.
for the seal journal you sould have just got a speedy sleeve as now you have decreased the O.D. of the spindle and changed the interferance so now it's going to allow water in and grease out much faster Oh well too late now.

Probably should have clarified better. Just took plumbers cloth and light emery cloth over the surfaces just to clean off any rough edges. Surely didn't take off much material. Just enough to shine things back up again. On the seal surface, there was one little burr or something that seemed to be eating up seals faster than it should. On the spindle side, just cleaned it up because the old bearings put a few light knicks in the surface. Hard to describe, but I only took off the material that emerycloth and plumbers cloth would remove. Heck, I could barely see any metal dust.
Sorry, should have clarified more.

If you are still worried, make a few extra stops during your trip to make sure the hubs are not getting hot.

might be time to go to some bearing buddies, I like them especially for boat trailers because of the fact that if used correctly the spring pressure keeps pressure on the grease and wont let water to enter because of the pressure
