AG100 Bushing replacement

Not hard actually. I’ve replaced mine twice.

I find it is easier to put a jack under the rear of frame by the mudflaps, lift the frame to remove the weight off the air bags a little, especially if you don’t have a dump valve for the bags. Make sure to chock the steer axle!!

Once you get the bolts out and remove the caps release the park brake if you have maxi’s on both drive axles.

I use a 4’ lever / pipe and put it up under the front of the rear drive tires and force the tires back a little, you can then push the bushing inward till it clears the mounting area.

Bushing is split on one side so just open it up and remove from the torsion bar.

Set the new bushing around the torsion bar and just force the tires backwards once again so you can slide the bushing back into the mounting area. Once again…. Chock the steer tires, having the park brake released will make it much easier since it allows the tires to rotate just a little.

Having the frame supported is your friend, along with dumping the air bags. If you don’t have a dump valve just jack the frame up a little more, less pressure in the bags will make your job much easier…..

Edit: When you do the front axle force the front drive forwards.

Rear axle backwards.

And make sure the bolts are out on both sides….

 

You’re more than welcome.

I spent 18 months rebuilding my W9L bumper to mudflaps. The picture below is from that time period about 11 years ago.

Notice how I have a heavy jack stand under the frame rail? I was replacing all the air bags, but I used the same support on both frame rails when I replaced the torsion bar bushings.

Chock front steer axle
Support the frame
Empty the air bags
Pry the rear drive backwards
Front drive forward

That was the simplest way I found myself.
Holler if you need anything…..

 

Your bolts look pretty clean compared to what mine were, I couldn’t even see them.

Spray some penetrating oil on them were they go through the aluminum, and after you take the nuts off you may just have to use the impact hammering back and forth to loosen them. Then again they may come right out….
