Just wondering if anyone is still having any Popping noises lately on your Hellwig 7254 Sway Bar after your fix? I have greased mine up, but every once in awhile when I hit a large bump-usually in a turn I get noises. Thanks.

Capt D...

On my 24S which I picked up a little more than a year ago(2011 model) I would occasionally get a "pop" (maybe rather a grunt?) from what I perceived to be the sway bar whenever I would tenderly back it down from besides the house, over a few roots from the maple tree, over a sidewalk, and then the curb onto the street(all on an incline).
I have to hang onto it and use a back-and-forth of throttle, brake, and also handbrake
to make sure it doesn't sink into any wet ground but also keep the momentum going...I'm getting good at this but managed to nurture a few noises from that area.
However, mine is a beefy RoadMaster sway on the rear so it seems they all succumb
to this problem once in a while. Esp. with the motions mine would have to go through
to make it down to the street...

Anyway...I think you and I also went round-and-round a while back re installing proverbial Sumo Springs to further help out? I think you convinced me to do this which I finally ordered and installed DIY (of course, in the rain...when else right? Was sunny and clear when I started...lol). To get to the point...I honestly haven't heard a peep
since then, esp. when backing it down over the convolutions. All four Sumo's CERTAINLY set the suspension
up for the highway on the rig and I feel actually tunes it up a bit! The ride is much more stable, esp. when in a dirty air situation with the semi's, etc., and I want to thank
you for the encouragement. And, no peeps nor pops! Did you ever put Sumo's on?
Maybe the RoadMaster brand AND Sumo's are made for each other...dunno? I hope
you win! When it's man vs. machine...man ALWAYS wins! Cheers! -PB

I didn't experience the infamous noise some had mentioned for the first 7500 miles - then it began. As others stated -- it only occurred on sharp turns or when rocking hard in rougher terrain. I looked and found I needed to retorque the bolts and the problem was solved. However, the inside tread on both my inner rear tires were badly worn and I replaced than at the same time I torqued the bar back to specs. I doubt the noise and tread wear are related, but thought I'd mention it

I also just installed sumo springs and the occasional creaks went away. I already had the helwig. Now I just ordered bilstiens too.

Just a note on terminology and such as I think there may be some confusion regarding Sumo Spring products. As near as I can tell, Sumo Springs offers 3 upgrade products which might be of interest to Sprinter motorhome owners.

The first is a simple rear axle bump stop replacement for the existing Sprinter bump stops - product number SSR-338-47. This seems to sell for about $200 / pair.

The second is a more significant replacement for the rear bump stop, product number SSR-336-54-1. Prices for this are in the $560 / pair range.

The third product is a front suspension upgrade, product number SSF-106-40, for about $150 / pair.

Anyway, when discussing SumoSprings or SuperSprings it might be helpful to mention exactly which product you're using or asking about.

Thanks!

Dave

Sumo Springs

Thanks DAVEJORDAN for asking for that clarification on Sumo springs as I apparently am confused. I only have 3500 miles on my 24R and tow a 6x12 enclosed. I get lots of side to side when being passed by a semi or following at 65 or so, I have factory installed Helwigs and am not sure what product to install to correct this situation.

I did the helwig and the maxim sumo springs. These are the second of Dave's list. I may do the bilsteins at some point but I'm quite satisfied with the current state of affairs. One interesting point is that there is a heat shield on the right hand spring, which is located too close to the exhaust pipe. As a result it (the shield) gets deflected downward (its fairly thin metal) and on bumps will hit the rear axle. Makes a weird noise. I had trouble figuring out what was making the noise. Once I got under the rig I could see where the heat shield was hitting. A pair of tin snips will fix the problem. But I called super springs to let them know. They are great at helping out. The tech had me take pictures. He'd never seen this before. It seems the exhaust in our rigs is slightly different than on regular sprinter 3500. It's a bit lower and further lateral so it comes in contact with the heat shield. He said the shield is made of light metal so it can be shaped to allow for this type of interference. I wish the guy who installed it had thought of that! None the less its very easy to fix. The tech also commented that the springs seemed heavily laden. He's used to looking at sprinter vans, and thought it was a good idea to add support to the existing suspension.
