Hey guys,


I noticed today that one of the front hubs has bearing play, while the other does not. Examining the hubs, I did not see anything that alows for pre-load adjustment. I'll describe what I see..


There is the hub, inner and outer sealed ball bearings, drive cup and hex nut for the wheel to slide over. Also, there is a pin going through the hex ( I am assuming to hold the pieces together ) and a set screw inside the axle tube. Im wondering if there is any way to tighten this assembly up so the hub does not rock up and down. I find it wierd how one side is tight, and the other has play, with fixed components. I was thinking maybe the bearings one the tight side may not be pressed all the way.


Also, this truck is new. Any ideas would be great. ;)

The best thing to do is use shims to eliminate excess play/slop with just a tic of play. You don't want any preload as this will create too much friction for these little bearings.
 
Great call Bill. I was not aware of shims for these, but will look into it. I guess preload was not the right word, sorry for that. I should of explained better. I realize ball bearings do not need adjusting, like a roller bearing, it is the hub that is loose. The shims will work for sure and im sure I can get some @ .005-.010" Thanks for the tip!
