Getting ready to replace air suspension

Recommended Posts

Thanks for all the replies. The truck has several airleaks and the bags are pretty sad looking. Just trying to get my ducks in a row. The plan is to remove the bed clean and rust treat frame and recoat. The way the bed is made thought it would be much easier to replace bags and fittings while it was off. I will look at the leveler and anything else and try to do as much as possible.

I bought the truck already made looks like it started off right.

Like they say an ounce of prevention is worth a pound of cure. This stuff is heavy will keep everyone posted.

 

Thanks Gary

Why change the fittings? All that normally goes bad is the o-ring inside. A couple of minutes well spent, to swap the rings and save the money for cigars.

 

Ever since someone posted the numbers for the o-rings, every time I work on an air line, I change the ring in the fitting. It's amazing how often they come out in pieces.

If you're pulling the bed off, I would change the torsion bar as well. It's cheaper and much easier to do from the top side than to struggle with it from the bottom. Change the rear leveling valve, and shocks while you're at it. Depending on how the bed is made and how close it comes to the rear of the cab, doing some part replacement at the back of the cab could be much easier as well. Changing the cab air bags and shocks is easier when you can stand between the rails than being half crouched half laying down trying to work over your head.

I would love to have the time and place to pull my bed off for a week or 2..... but I've already changed all the hard stuff.....
