Airbag thingies

[bidibronco]

I have the airbags inside my coil springs on my front end. Anyone know the main reason they're there? I'm assuming they can have air added to them or taken away given the size of load on the front. Anone know what the PSI max and min is on these things. The main reason I ask is my front end is sagging probably an inch (makes for bad leaning of tires and odd wear) and was wondering if I can add air to them and get the front end back to par. I would go get a new set of springs and such but I don't drive my truck often at the moment (gas is rough in that thing) and I'll be putting it up 6" next year and don't see the point in new stock springs at the time. Another thing, when I go anywhere above 35 or 40 my truck has a nasty shake, not the front end shimmy but just a killer shake from all 4 corners, would this most likely be due to unbalanced tires? Well, any help would be great, thanks....

might be the tires, have you checked the u joints tho? if you put air to the nags your front end will greatly rise, ive done that in the past to a few rigs, makes for a stiffer ride tho

Well, I do know that every bushing on my front end including radius arm bushing axel bushings and all that good stuff needs to be replaced but the U joint look perfectly fine. The only thing I can think of why the truck sits lower is becuase the weight of the motor was off of it for a while and the truck was at a bit of a slope. But I just want a temp. fix for now so I don't wear out the inside of my tires to fast....

i advise you to replace the front end asap, TTB front ends before extremely unsafe to drive when worn out, replace axle piviot bushings,radius arm bushings, ball joints, steering linkage and alignment, and the bearings and races. i doubt your springs would sag from sitting on a slope with no weight on them, if u want to save your tires, you could try pumping up the airbags, but i would replace everything to eb honest

I will eventually but the most it drives is from my friends house (where it's parked at) to my place to get a good wax job every now and then other than that it just gets started and maybe turned around at his place...

The helper springs/air bags I've seen on a few Broncos with the snow plows, or if someone added them on their own. 20-60 psi is close, but they will stiffen the ride with more air. You could have unbalanced tires, or bent rims. The stock rims are bad about getting bent and shimmying. JSM84
