Oh, hey ... THAT's why my front end looks low

Finally got around to checking the PSI in the air bags inside the springs. The right side was really low: 0 psi.

The left, however, had a full 0 psi in it ...

You must be on a GM chassis. Over the years, I had to replace leaky air bags several times. Finally did a permanent fix by installing heavier coil springs, thereby eliminating the air bags. Expensive fix, but ride was much improved.

Just being silly

I've read a lot of posts by people about how replacing the air bags is fairly simple you just need the correct tools: profanity and knuckles to bloody. Currently debating whether to go through that or pony up for heavier springs.

How much did it cost to have that done?

I don't remember exactly, but in the $500 - $750 range. They did a couple of other things as well. I traded it off a few months later for a different RV, but while I had it, was pleased with the ride results & didn't have to worry about the air bags going flat. The upgraded springs were at least twice as thick in diameter as OEM. Go to a truck repair facility (avoid CW or a RV dealer for this type of service) and talk with them.

Good luck.

BTW, my installer wasn't impressed with Supersprings specs. You might want to avoid them.

Thanks for the info!

I have finally found a reliable large truck mechanic just over 10 miles from home so I've got the right person/place for a job like that. The cost of installing stiffer springs isn't as horrible as I thought. I might want to look into that.

How long did your airbags last when you were replacing them?

Also, are you saying you got these installed instead of replacement airbags?

It was on a 2003 Winnebago Brave that I bought from original purchaser in late 2003, early 2004. I sold it in mid-2013. If I remember correctly, I replaced the bags at least twice due to holes being worn in them. Could have been my fault for not checking them often enough for proper inflation. I had one bag explode on an earlier GM chassis motorhome after hitting an unavoidable road hole. In my way of thinking, it was a way for GM to save money by installing less expensive springs on their chassis. The aftermarket stronger, stiffer coil springs also increased the height of the front end. You might want your mechanic to look at your rear leaf springs for adequacy for weight they're tasked to carry. My Winnie also leaned toward the passenger side. My next planned project was to have that issue corrected by adding shims and leafs to the rear springs, but I traded it for my 2013 Newmar before I got around to it.

Keep us informed of your decision and progress.
