Getting ready to replace air suspension

oldride · February 17, 2017

Getting ready to replace rear air bags on my Volvo. What is the best way to ensure i get the right bags. Vin # or axle make and model.

Or something else?

thanks Gary

Vin# works best. What I did was get a Volvo part number and then cross referenced it to a Goodyear bag. Cheaper than getting the Volvo parts counter to walk back to the shelf. I paid $90 or so each for mine free shipping from an online parts house.

VIN # worked for me. Don't forget to get the star washers at the bottom. They don't come with. You should get new air quick connects, too, (1/8 inch NPT). Are you going to replace the air leveler? New shocks?

I had to replace the cross member and everything up from there.

This is a previous post on the cab air springs: http://www.rvnetwork.com/index.php?showtopic=125467#entry870662

It has the part numbers for my 01.

Gary, If you want the parts pdf for the parts, PM me and I will see if I can get it to you.

Looking back at his first post, he references the axle, so I'm gonna guess he's replacing the suspension bags..... But I've been wrong before. :rolleyes:

Oops, I think you are right. Sorry!

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.

Wish someone would repost it. I tried and could not

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.....
