I had both front wheel bearings replaced at about 170,000 miles ago after the originals failed within five days of each other. They failed because a shop tech tightened the big nut that holds the rotor/hub on the spindle way to tight. The front drivers side failed on long trip with little warning, luckily I pulled over and as I was nearly stopped the wheel tipped sideways. Five days later the other side went out and the shop warranteed their work. Skip ahead 45,000 miles and the front drivers side fails again. Found a shop to replace it last week as was going on 500 mile trip. Within 250 miles it's going out again, low pitched vibration in floorboards and sounds worse worse than before. Question is how could this happen so soon?
The guy who did the work said he had hell of time getting the races out, like they were out of round and the inside surface where races go was real rough. So ,put new rotor and bearings in. Could the spindle be screwed up from first failure? Sorry , this got long.

 

I dont think it would cause damage to the spindle shaft without a noticeable score marks or at least severe blueing. If the inner rase of the bearing went on with no porblem or play then you should be all set.

 

Will be pulling and inspecting tomorrow morning. This should be pretty elementary. If it's anything of interest will post the results.

 

Let us know how it goes for you. while you have it apart you might as well put some new grease in.

 

What I do to front bearing after a re-pack. When all togeather I turn the nut 1/2 to 3/4 turn and turn the hub a few times to set the bearings. Back the nut off all the way. Preload the bearing with just less 1/8 of a turn, and put on the cotter pin. I never had a problem with the bearings that I repacked. Make sure to use high temp bearings greese too. GP or chassie greese will not work.

 

figured it out today. The front left had the wrong nut, from when I had it fixed on the road 4 years ago. When the wheel tipped it must have gnarled the original and being a sunday the guy scavenged it back together. Funny tho,had rotors/hubs changed and bearings repacked twice since then, and no one noticed the left was different than the right. Of course not one in town, getting overnite from Minneapolis. What's next!
