I have a driver side steer tire that is wearing uneven on the second rib in from the inside, and some on the inside rib. Tire only has 15 to 20,000 miles on it. Passenger side tire is not wearing like this one is. I need to jack up the front end and see if I have anything loose, but any ideas what I might need to be looking for? This is on a 1995 fld120.

Jack it up under the front axle on that side and pry between floor and tire to check for king pin slack. Also pull side to side to check for tie rod slack. I wouldn’t be surprised if you have a bad king pin though. Probably both are bad. Other than that, check air pressure and your alignment.
Could probably be your bushings on the leaf springs too. Look closely around them to see if there’s any shiny metal to show fresh rubbing.Rideandrepair and singlescrewshaker Thank this. -
Check wheel bearings for any slop as well

Check the passenger front for feathering on the out side ribs.
If it has outside feathering the rear axel has right thrust and you have a rear axel alignment problem.OldeSkool, Rideandrepair, singlescrewshaker and 1 other person Thank this. -

Might be a long shot, but when I steer all the way to the right, my left steer makes contact with the end corner of the pitman arm. Then those two ribs get kind of beat up, and it wears them down faster. Rest of the tire, and the right side tire are perfect.

Take it to a good alignment shop not some truck stop with a machine and goons running itOldeSkool, Rideandrepair, God prefers Diesels and 3 others Thank this. -
I Highly recommend any of the MD alignment shops.
There common sense old school approach can not be beat.
They are the only ones I use since I had issues with failed high tech laser alignments.
Since the MD alignments I have had Zero tire wear issues and it tracks straight down the road with a straight steering wheel.Accidental Trucker, Mattmanstroked, OldeSkool and 5 others Thank this. -

FLD my guess is the leaf spring shackle/hanger on the rear of the steer axle springs. Can get more shims from freightliner, or just replace it..
Mine is on the list. Kingpins & wheel bearings just done..Swine hauler, Hulld, OldeSkool and 2 others Thank this.
