steering wheel vibration

The steer tire isn't set right, which causes the issue, somehow they get unseated or are not seated properly, unfortunately when they go to take it off and try and balance it you will probably be about 20 lbs off which means new steers.

i had that happen once

 

20 lbs holy cow you must mean ounces

 

Yes, I did was in a hurry, but the conclusion to the story is that if your tire did unseat and they remove the tire well they won't be able to get the tire back on the rim. Most troubles when vibration starts at around 45-50 but then the vibration seems to go away either below or above that speed generally it's the cause. Just be prepared to buy 1 or 2 new drive tires if they remove them.

the wear is usually at the bead where the tire sits on the rim and only way to know for sure is to have the tire removed.

 

you said a weight fell off and your using centromatics. you shouldn't have balance weight with centromatics. That will create a shake. worn steering box or loose pitman arm will create slop in the steering. Replace the damaged tire, remove any balance weights if your using centromatics, check wheel bearings and do a alignment.

 

One thing people never think of is dirt inside the rim. It builds up, even if you run mostly pavement and will unbalance a wheel, I clean the insides of my steer rims about once or twice a year.

Also check, sometimes when people grease the trucks they put a lot of grease in the ends of the tie rods and it bleeds out and drops on the rim, collecting dirt also.
