35mph + vibration

[sparrow]

2003 4wd se pathfinder. Frame/body vibration 35mph + . Worse under load and worse in 4wd. Wheel bearings tighted and repacked. Any help appreciated. Thanks.

First, a thorough inspection of your suspension is in order.

If everything is solid, try removing your front driveshaft and see if that solves the problem. There are other culprits for such a broad problem, but if it's worse in 4wd, I would start there.

Another member here has actually removed his rear shaft, and that was his culprit.

Personally, I know the front shaft is my culprit, but at 45 mph the vibration goes away when I turn on 4wd, then gets worse when I go over 60 mph.

Good advice
I've had the front driveshaft go bad on an 02 QX4 4wd, swapped it out and was back in business. Also check driveshaft center support bearing for tears.
