Peterbilt low air leaf alignment

Out as in left to right? But only on one side? Do you have an oddball hub there or maybe a rim with a different offset than the rest?

 

Check your U-bolt top plates on the leaf springs. Make sure they are not cracked, or haven't shifted. Also, check the U-bolts themselves and ensure the u-bolts are not broken, nor have shifted.

These issues can be be the cause of your misalignment.

If any of your top plates are cracked, they will need to be replaced, along with the u-bolts. Don't reuse old u-bolts. The top plates were made of aluminum, but they make replacement ones out of cast steel I believe.

As for fixing it yourself, why not just take it to a shop where they have the right tools to get you in and out? It's not as simple as pushing or pulling it into alignment.

Good luck.

 

Measure your frame to inner tire clearance(tape measure). It is likely if you have ever had the tracking arms replaced that they were reassembled incorrectly or the shims put on the wrong side of the axle/arm. This will also give the appearance of leaning air bags. Measure all four corners and shim or add washers to get em straight. After shimming- drive and re-measure they all match. Checking to make sure no u-blots are loose is a good idea also.

 

There are special 1/2" thick spacers on some but you can utilize 5/8" Grade 8 flat washers just the same for minor adjustments. The arms on top of the differentials are the tracking arms. Either take away or add washers between the housing bracket and the arm to center the axle to the frame depending on which way they need to go.

 

You are welcome, hope you get her running straight.
