AI 2015 steering wheel vibration at speed over 65

I brought her to an sprinter MB dealer for alignment ,although it improved a little bit , I can still feel the steering wheel shake/ vibrate when doing 65 mph or above.
It is just normal to feel that due to the size of this motorhome?
Thanks.

I've never felt it on mine at any speed. Other Airstream Interstate owners have reported the same phenomenon, however. I don't know what their solution was, but if tires are out of balance it can contribute to vibration.

Jack the ft tires just off the ground and spin them to check if they are true. Next would be to get them rebalanced.

It is weird. Mine does it sometimes....Seems as if the road surface is a contributing factor. I am starting to think it has something to do with the steering dampner, if these have one. On some roads smooth as can be, others, shakes.

Do the road surfaces where it shakes have a high crown as opposed to being more-or-less flat all the way across all lanes? On roads with a high crown, in order to travel straight you need to add a slight bit of left rudder so that not only are you going ever so slightly uphill all the time, but the tires are "crabbing" a bit to the left rather than tracking completely straight. That can also contribute to uneven tire wear.

Not sure. Maybe. Tires appear to be wearing even and at 12,000 miles have a lot of tread left.

May be a flat spot on the tire. This happens sometimes when the vehicle sits in one spot for a while.

Mine did that when I first got it at ~4K miles and they rebalanced the fronts and all good since. Then after I had rotated and rebalanced, it's back. So back to get rebalanced again.

Mine does it at first drive when tires are cold. Then goes away

Or you could just drive 64mph

Not a normal situation. I would check tire balance and possibly go for a road force balance or even better is balanced on the vehicle. Any shop that does high performance/racing tires most likely has the equipment.

Rebalancing the tires fixed mine. Weights fall off sometimes.

I had shimmy/vibration issues for a long time. Balanced and rotated the tires many times to no avail. It was also accompanied with outer edge front tire wear. I ended up getting an alignment and setting the camber to 0 degrees. It solved my problem. No wear or shimmy, no vibration for the last 8000 miles. The thought is that the EXTs (which I have) carry a lot of weight in general, particularly beyond the rear tires. This weight 'unloads' the front end and causes the issue.

There's lots of opinions on this one way or the other. I did it; it worked for me. Maybe you can give it a try.

Below is a post that I put on the Sprinter-Forum. I wish you success In figuring out your problem.
--------
Re: Left front tire wear
Thanks to this board,I believe my front tire wear problems are now fixed. An alignment to zero degrees camber seemed to do the trick. At 10K miles, I had bad enough wear on the outside edges that I bought new tires (Michelin LTX M/S2) to replace the Continental Contis.

I went to a local shop in San Jose, CA (Ross Truck and Equipment Repair 408.292.1464). I took with me a set of camber adjusting bolts from Upscale Automotive. The team at Ross really liked the functionality or the bolts. They said it made the job super-easy.

My pre-alignment figures were 1.5 degrees (drivers side) and 1.25 degrees (passenger). Post alignment was 0. I can't recall what the Toe was, but it was reset. I have since put about 1000 miles on tires (we are on a road trip). I'm getting even, consistent wear across the treads.

I should also note that I installed Sumo springs (front and rear) before my trip. They have made a big difference and I am quite pleased with them. In the past, I put adjustable Konis on the rear as well as a bigger sway bar (both from Upscale). They made a big difference, but the front end was still a bit soft. The front sumos seemed to fix that. The rears seemed to address rear end sag (I have the extended sprinter, 24+ feet). Overall, the ride is much more dampened over bumps, in high winds and taking off-ramps. I was going to go with Koni struts in the front, but couldn't get them installed in time for my trip. The sumos are super easy to put on; especially the front. About 5 minutes per side. The rear installation is easy also, however there is just more stuff in the way to deal with (ie, my generator and lower ground clearance).

Once again, thanks for everyone's input on the alignment specs.
