How do YOU tighten front wheel bearing nuts?
I know what the books say, even Chilton doesn't agree from book to book. Both say tighten the nut to 50 ft. lb. while turning the wheel. One Chilton manual says back off about a third of a turn, another (also Chilton) says back off 1/4 turn (90°) maximum.
I've got them front and rear with the Summers Bros. full floaters and using the above method, seem to be getting some vibrations above about 60 mph if the pavement is not really smooth or when making highway turns. In a tight highway curve, it feels a little unstable. With a corner jacked up, I can feel some looseness or play in the bearings.
For years I've gone by feel. Tighten down pretty snug and back off until there is little or no drag. For castle nut and cotter pin, it's usually back off to the next slot. I've readjusted the ones on the left side using my method and the vibrations are fading and the stability is returning. I'll do the right side this afternoon.
The main reason I'm asking is because I had a bearing retainer come apart after several years, and cause the outer race to spin [img]images/graemlins/burnout.gif[/img] in one of my high dollar Summers Bros. hubs. There was still plenty of grease. The grease leaking out, once the bearing got hot [img]images/graemlins/puke.gif[/img], was how I located the problem so easily.
So what do YOU do?
