The Nissan Path

Hey guys just signed up today and im in need of help! I own a 2007 Pathfinder LE 2WD. Ive been experiencing shaking and low humming noise between 35-40mph. I just got the ujoints replaced but still problem exist. Has anyone experienced this problem and have they been able to resolve this problem? Thanks guys

It could be bad wheel bearing(s) or bad tire(s).

It might be but the tires were bought around this time last year. The bearing might be. But the shaking I can feel it like its underneath the vehicle. I did a little bit of research and other owners are saying it might be the driveshaft but with no definite solutions. I dont want to take it to the dealer because they charge too much and I already spent $489 just to replace the ujoints.

I'm no mechanic, but I've read that not being carefull with the drive shaft can cause vibrations and such. Being you just had the u joints replaced someone might have goofed?

The driveshaft usually vibrates because of bad U-joints or because it gets bent or because it throws a balance weight off. Since you already replaced the joints, I would just to see if there are any dents or "shadows" where a weight previously was attached. One year old tires can still go bad... Check for play in the wheel bearings.

jack the tires of the ground on the back and try and "wiggle the tire back and forth. takes a few minutes and that way you can find out if it is the bearings or not. or you can eliminate it. i just replaced both rear wheel bearing hubs myself and it took like an hour total and costed $200 canadian,.easy peazy
