How to Scare a FlyingJ Tanker Driver to Death

I had a blown bag when I purchsed my unit, and replaced them with new Airlift bags. I put them at 55psi, and I don't really notice any differance... What pressure are you guys using? ...and what kind of differance do you feel?

Troy, I think my Airlifts were rated for 1000 pounds at 90 psi. It's very noticable when they are not inflated.

I dropped my springs to replace the bags. You need to pop the lower ball joint. The big thing is to ensure you supplort the control arm with a jack to control the string. I can't imagine stuffing that bag thru that hole!

I have had the luck to replace my front air bags twice. I paid a shop the first time and they dropped the springs to do it. I also had to add the cost of a front end alingment to the tab.

The second time, I read the instructions on this forum and it worked like a charm. The way I got the inserts in the bottom was to use the jack to push up the bag. I used a plastic handle off of a toilot auger to pry up the bag. The handle had a hole in it that fit over the schrader valve. Once in half way, a little prying with a wide blade screwdriver and in it went. No front end alingment needed this time.

I also added an Air Lift Dual Command pressure gauge to the system. I ran a new air line to the front and put in a tee. One line went to the inside needle of the gauge to tell me the rear pressure, the other line went to the front needle and the front bags. I can add or bleed air to the front bags with the switch.

My hope is that by knowing the pressure in the system I will not go off "deflated" and ruin another set of bags.

Just a thought, is a higher rated spring available?
