adept99 Posted January 30, 2015 Report Share Posted January 30, 2015 Are the Cab Air Bags adjustable? Truck is very comfortable motoring down the road, but in moderate to higher speed curves, the body roll seems excessive. I know the bags were replaced by the previous owner, but I wonder if the bag inflation pressure is correct or maybe has leaked off over the last year or so. Thoughts??

Dennis M Posted January 30, 2015 Report Share Posted January 30, 2015 No adjustment that I know of, and even with some leakage the pressure should stay pretty steady.

jkennell Posted January 30, 2015 Report Share Posted January 30, 2015 The cab air bags work on the "level sensor" principle, just like the rear suspension. Pressure depends on how much weight you have in the cab, to hold a certain height. The only improvement I could see would be to move them out to the edges of the cab--but that would be a big job approached cautiously! Oh, and take all those heavy cans of (Insert favorite beverage here) off the top bunk and put them on the floor! I do understand what you are saying--I've wondered how one could put a "roll bar" on the cab before! No camper at present. Way too many farm machines to maintain.

rickeieio Posted January 30, 2015 Report Share Posted January 30, 2015 I agree with Jeff on the placement of weight. Any added weight up high will increase body roll. These things are already tall, especially the 770/780 series, or any other double bunk cabs.

Alie&Jim's Carrilite Posted January 30, 2015 Report Share Posted January 30, 2015 I've noticed on ours, that there was more body roll than I'm used too. As soon as I started to paying a little more attention to those little yellow signs, the issue went away. Especially up in the hill country of Texas. It's sometimes hard to remember what we're driving sometimes as comfortable as the trucks are.

Bob A Posted January 30, 2015 Report Share Posted January 30, 2015 The shocks may need replaced they dampen the roll and bounce just like suspension shocks.there at the back of cab near the air bags. 2014 jayco siesmic 3914 1998 volvo 610, singled short ( bought in 2005) 14 speed volvo tranny 2014 Toyota yaris Link to comment Share on other sites More sharing options...
phoenix2013 Posted January 30, 2015 Report Share Posted January 30, 2015 1. These things are tall and roll more than anything (lower) you are accustomed to. 2. Don't chase it with the steering wheel, you gonna make it worse, it will come back to neutral "without help". 3. If it's "really, really" excessive the cab shocks could be bad, or 4. Your panhard rod (the "dogbone over the axle) might have worn rubber bushings and needs replacement. Link to comment Share on other sites More sharing options...

adept99 Posted January 31, 2015 Author Report Share Posted January 31, 2015 I know the cab shocks were replaced at the same time as the air bags, 2-3 years with <10K miles on them. I drive one of two tri-axle dump trucks part time to keep me off the streets. One is a big 'ol stiff Mack, the other is a converted freightliner road tractor. Before anyone says "they aren't comparable", the Mack was doing this body roll thing & I found a couple of worn bushings and a broken spring leaf on the driver's side. The freightliner still has the single frame with heavy springs, but it doesn't roll much at all. I usually don't try to "catch it" unless it's half in the other lane and the other oncoming truck is bigger than me... Panhard bar bears looking into. Thanks for the responses.
