Default Vibration from front end at highway speeds

I’m trying to figure out the vibration that shakes my steering wheel at highway speeds. When traveling at 75-80 mph there is a significant vibration that comes and goes. I say the vibration comes and goes because if it’s vibrating and I come to a turn on the freeway the vibration seems to disappear on the turn, only to continue when I return to straight. There are times it doesn’t vibrate at all, then after a turn it comes back. I drive the same highway weekly, the car doesn’t only vibrate on the same stretches of road. My wife’s Subaru doesn’t vibrate on the same stretches of road.

The car is a 2015 with 30K miles. I recently replaced the tires, went from a new set of the crap OEM Hankook Kinergy GT to Pirelli Cinturato P7 All Season Plus, there was no change in the vibration so it isn’t tire related. I didn’t change the tires for the vibration issue, the Pirelli have much better snow traction.

I’m thinking the issue must be related to one or both of the CV shafts, maybe there is a dry CV joint or something. Anyone know if I’m on the right track, and if this might be covered by the 2yr/unlimited mile CPO warranty? This car was a buyback that sat for 6 months in the desert, not sure if it would make a difference. I’ve had it for 4K miles.

Thanks!

I've had random FE vibration before, in different VAG autos, and found it was antiswaybar link bushings. Cheap, simple replacement.
Others with NMS Passats have had early link bushings failure.

Others for sure will weigh in.

Have your wheels and tires spin-balanced again to rule out tires as a cause of your problem. The tech may not have balanced one or more tires correctly, or a balance weight may have fallen off since they were installed.
Most tire installations come with lifetime balancing, so your cost to eliminate the problem could be $0.00 unless you are 100% positive both new and old tires were properly balanced.

I’ll tug on the antisway bar links and see if anything is loose.

I had the Hankook tires balanced at 28K miles, no change in the vibration, one of the rear tires needed 1/4 oz added. I haven’t had the Pirelli rebalanced, they went on a week ago Thursday and the vibration is the same as the Hankook. I’m 99.9% certain this is not a tire issue as the vibration is the same on two different sets.

I had a similar vibration issue on my Touareg that was a tire issue, but there was vibration all the time on all road surfaces. Discount tire ended up swapping the Yokohama tires for Michelin and the issue went away.

I had the exact same issue that oddly enough, Pirellis solved. These are very good tires, bring them back to your shop and have them road forced again. If they’re still in balance, next stop would be a rim repair shop to check for an out-of-round wheel. It could be misshaped enough to cause a vibration when going straight on a smooth surface, but go away when load is applied to that side of the car, causing the tire to pick up and smooth it out.

I think a bad wheel is more likely. I went though 4 Continentals before swapping to Pirellis... it happens!

My vote is bent axle.

Hound the tire guy for another balance but be prepared for investigating a slight bent axle.

I've heard "raxles" are way cheaper than OEM and put them to shame. If it is the axle, good luck having the dealer replace, they will say you caused the issue with a pot hole or something.

Wouldn't a bent axle create a constant vibration, regardless of road imperfections?

I would think that a bent rim would never ride down the freeway smooth, it should be consistently bad. I had a 5 mile straight stretch on decent pavement today without any vibration at all.

I've got a decent relationship with my dealer, I am a contractor for them as well. I'll jack everything up next weekend and see if I can spot anything spinning the tires by hand.

had my dpf heat shield recall done last week, they said that the orgional was to short and heat can melt the inner cv boot and cause grease to spray on the dpf causing a fire and also causing the inner cv to run dry- id check it out

my only thought was that as he turned it put different load on the axle that balanced it out thus removing the vibration.

But again that could be tires, or rims.

I had issues with the vibration particularly under load at 70 MPH. Putting new set of tires by VW dealer and have them balanced using road force and the alignment at VW Dealer, the problem completely gone. And since then I had put over 30K still no vibration at all. I would take it to a reputable VW dealer to get it checked.

I’ll have mine checked by the dealer when I go there for work the first week of April. I’ll rotate my tires front to back this weekend and see if it makes any difference on my drive this week.

Interesting. I just got a 15 with 27k miles and have the exact same issue. Looks like they replaced the Tires Battery and possibly brake pads. I read somewhere that these were supposed to get new rotors also. Not the case with mine. I had the tires balanced and its much better but still there. They put Nitto Motivo tires on it. I will rotate them also to see if that helps.
