tie rods and kingpins are good....always check tire pressure at least 2x weekly.....and my front passenger steer tire wears in the inside??? what am i not checking on??? ive had 2 alignments done the past 3years...should i do them more often???

 

Have the rear axles also been aligned ?

 

I had mine aligned 3 weeks ago, front drive axle was 3/32 inch too far back on right side, rear drive axle was 4/32 inch too far forward on right side. I now know where the unusual wear on my drive tires came from!! Checked my mileage before the alignment, average of 6.2 mpg, steady 6.8 mpg since then, same terrain, same driving style.

 

Maybe new shocks?

 

well b4 i had it aligned steering wheel wasnt centered and if i let go of steering wheel it pulled slightly to one side....got it back steering wheel still not centered and still pulls off to one side........ could it be the 129$ deal i thought i got for the alignment just wasnt done right?....i got a printout of measurments but i dont know what that means

 

What people are talking about is a 3 axle alignment. For that price it was just the front. When you have a 3 axle alignment tell them about your tire wear.

You can also go to a tire shop and ask them. No one can answer for sure without looking at truck.

Not every shop checks over the front end like they should. I got tires an an alignment in TN once. I took old tires with me and my local tire shop saw that and rechecked my front end and found problems they didnt catch. So find your self a good tire and alignment shop and go from there.

 

no that 129.99 was for a 3axle alignment from snider tire in greensboro NC, :lol:

 

At that price I'd go somewhere else. I can't imagine a place that does a quality alignment doing three axles for that. How much faster is the tire wearing? How many miles are on these tires and do you rotate them regularly? The manufacturer specs usually call for there to be a little pull to the right. This is supposed to be a safety measure so that if the driver becomes unconscious (sleeps) the truck will drift toward the shoulder rather than the middle of the road. A quality alignment shop should be able to show you what the base specs are and how far out of spec you are. Are your tires balanced?

 

i put those steers on there last may or june, and noticed wearing maye 3months ago, got alignment and it still wears!!!?!?!

 

were the tires swapped from side to side part way through the tires life?

do you have a vibration/shimmy?

has it been in a shop to diagnose a pull problem?

has a rear axle shifted (relaxed u-bolts)?

has a spring been replaced?


hd truck steering pull is generally caused by the rear axle thrust angle or steer axle radial tire pull. if the pull is caused by drive thrust angle, usually the wear will be seen on the inside of one steer tire and the outside of the opposite steer tire

wear on the inside of both steers could be caused by extreme toe-out condition (would have been wandering all over the road before it was corrected) or low camber on both sides (very unlikely). otherwise, multiple problems are necessary to cause such a wear condition.


as far as your printout goes; drive axle thrust angles should be close to zero degrees (slightly positive ok, negative not ok). if it's a tandem the two axles should have the exact same angle. the toe should be slightly positive as well (never negative)

the steering "off-center" might be due to the pull, when you let go of the wheel, does it center itself?
