It may not be the alternator causing the vibration - it could be something else being driven by that belt. I would take off the belt and check the idler pulley first, then the rest to see if there is a misaligned pulley or one of them is very rough or loose when being manually turned.

check your pulley's. Sounds like one of them are bad and causing movement which where the vibrations coming from. A friend of mine had the same problem, his was the fan pulley. It could be moved inward and outward a little but enough to cause the engine to vibrate. The bearings were going out. check it out and let us know what you come up with.

have the front end checked for worn parts, something is worn out, hard to say without hands on look at the parts, any tire shop like Big O will do an inspection for free.

Some time ago I got new tires put on my 2010 dodge ram 1500 and after that the truck kind of vibrated I figured just the tread off the tire so I ignored the vibrating. Now I currently have abs. Esp....


If it wasn't vibrating before the new tires and was fine then it has to be the tires maybe just one, or sounds like they didn't torque the lug nuts to the right specs, putting the rim out of alignment, but if they took the wheels off to rebalance then that rules that out. I would go to a different tire shop and have them check it out....Also on a long shot they bent something in the suspension when changing the tires, possible fell off the jack or something similar. Good luck

Could be wheel bearing. Make sure your tire isn't rubbing anything. Make sure you haven't blown any of the steel belts in your tire. Typically if it was your bearing it would have slowly gotten louder, not just all of a sudden unless you hit something. Good luck

I use to work at a Nissan dealership. It sounds like your are having problems with the torque converter. When the CVT gets replaced, the torque converter does too. They may have gotten a bad part and need to do a parts warrenty on it. Another thing is that they may need to reprogram the TCM. This is another step that should be done after replacing the CVT. If they will not do anything, I would try to find another Nissan dealership and have them look at it.

I had the same problem with my new Defenders. Turns out I had a bad batch of tires. Not only had vibration, it caused the car to pull. I had the tires tested for roundness, and three were out of round. Additionally, two of the tires were causing what is known as radial bias pull, which made the car seem like it was out of alignment. Three alignments, four rebalances and rotations later, and with still a lot of of resistance, they replaced all four tires as defective, and the problems ALL went away. You need new tires.

Vibration in the steering wheel on a 4wd truck


I just had the same issue with a 1999 2500HD and the vibration got worse above 50 mph. Problem was resolved with a new driveshaft. Old one (aluminum) was badly out of true and the problem didn't really occur until I had the U joints changed - then bent driveshaft vibration was noticeable. New driveshaft resolved issue.
