I was wrong about everything! (Suspension problems, part 2)

We went on an expedition into town today, and got some real data.

First stop, the scale. My rig, loaded for travel, is only a hair under the GVWR. Like a case or two of water, or a full gas tank, under.

Next stop, my friend's trusted mechanic (not a suspension specialist, but an old guy with lots of experience who does not upsell).

He said that my leaf springs are not shot, Unlike the guys on the van forum, he thinks that basically never happens. He said they are flat because of the load, and since I have already added heavy duty shocks I should add a leaf.

He said the sway bar is ok. I am a little hesitant about this because I was not under the van with him, pointing at what I thought were cracks. But he said if they were cracks, it would be broken all the way through because of the stress it gets. Could it just have lines/ridges in the metal, at the bend points?

He did say I need bushings for the sway bar. Someone on the van forum said that was the best $15 they ever spent.

There is of course the question of whether adding a leaf, which requires fabricating new clamps, and changing the bushings, which means taking out the sway bar anyway, would save enough $$ to matter.

So.. what do y'all think? Am I doing the wrong thing to use this van as a camper, if it is going to be right around the GVWR all the time? Or can I beef it up enough that it will be ok for 10,000 miles? I am not trying to get another 100,000 out of it ;).

  • I expect if you need to sleep in it, they'd either let you stay on their lot, and maybe plug in, or let you take it and return again in the morning. Depending on what they do, it is most likely less than a day's work. They are pros and have all the tools to do things fast. Adding leafs, working with sway bars, those are jobs of an hour apiece, probably.

    Thanks, folks!

    I agree that I need to go to a truck shop. How do you handle major repairs like this when on the road? Do you get a motel?

    One of the things I am trying to figure out whether the work can wait until I back at my S&B. Or whether some needs to be now, or all.

    As for the questions above, I can answer most of them. It recovers normally on speed bumps, including taking them at an angle (sorry I forgot to mention that in the first post). It does dip down a lot, feels squishy, but it bounces once or twice and settles quickly.

    Weight info when loaded for camping is in the first post. It's right at the GVWR.

    Driving info: Normally, mostly mountains, on minor paved roads and some dirt/gravel. But, between here and my S&B, where I am headed next, mostly highway and interstate, involving a few mountain passes. Not going to stress it a lot unless it is repaired first!
  • I added a leaf on my F150 and was very happy with the result. No more squishy smarmy towing. It added about 2" to my unloaded height though.
  • You can throw all the extra springs you want at it GVWR isn't the max the springs can carry it's the max the axles and other running gear can carry. If you want to keep it for another 10,000 miles loose some weight. Or run what you have and don't add any more weight.
  • Go to a truck spring business. The one in my area is awesome, they know their stuff. What you are trying to figure out, is what they do every day. And they do work on pickups and vans.

    Really, I would head there asap, fully loaded. I know you like your mechanic friend, and his recommendation may work. But I'd go to the real pro. Your rig needs some serious work, not some band-aid that might work.
  • Need test data. What happened to the speed bump test?

    People are throwing out suggestions without really knowing what's going on. Blind mechanics. Keep replacing parts until it works.

    Sounds like your maxed out on weight. Instead of adding another leaf spring you may consider adding sumo springs.
  • Nobody on here can accurately answer your questions. We haven't seen your van, do not know how close you are to max when fully loaded for camping, do not know what terrain you use it in (flat, hilly, mountains, etc.),the road conditions you will be operating on such as nice smooth interstates or a dirt road full of pot holes. Only you can make the decision.

    1) Add a rear sway bar.
    2) Roadmaster active suspension.

    I assume both of these are available as easy bolt on kits.

    Front sway and any other bushings can be replaced.


    Yeah, that's what I mean by beefing it up! I just wanted to give folks a chance to tell me no, don't do it, get a different vehicle... I don't want to, not after putting all the effort into camperizing this one, but I'd want to even less if I first spent another $1500 on it.
