Front end sag

40' international amtran. 98 push dt466e. Replaced the tierod ends and drag link. The front appears to be too heavy. Is there any way to bed up my front suspension?

If it is sprung with leaf system, they could simply be tired and in need of replacement or re-arching.

Pictures please.
You would need a fairly elaborate, and heavy conversion to over load your steer axel.
Did it squat before?
Do you know the axel weight?
What Tango said.

Are you sure the front is too low, or is the rear too high? Does this only happen after the bus is fully aired up? Why I'm asking is because some buses have air suspension at the rear only, and if the level valves for the rear air bags are not set right or stuck in one position, they could cause the rear of the bus to sit too high, like a stinkbug. Just a thought.

Or if you have front air bags, is there a kneeling position for them?

A 20-year old bus should not need its springs re-arched. If there are springs at the front, are they still slightly arched, or flat, or bowed up? Do you have enough air pressure in the tires? Under-inflated front tires will squash down more than under-inflated rear tires.

I'm going to check the rear end. That's an interesting idea.
The front is 2 springs and 2 shocks. I'm getting wear on my driver side tires. Like i said, i replaced the dealing and tie rods because they were shot. I'm going for new shocks next, but thought being up the front end would help.
I have my battery bank over my drivers side Front wheel.
