I recently installed a new rear wheel bearing about two weeks ago. Since then SOME of the noise and a little vibration is still there between certain speeds (I would say 30-65MPH). Since then I have throughly checked each wheel for movement and they are all tight as a rock. It is NOT a brake dust guard making the noise.

When I installed the new bearing I did not grease anything because it comes as a sealed unit (NOT like the front where you need to manually press in the bearings). Should I have greased the inner area of the assembly when I put it in? I am not sure if this assembly is called the "bearing assembly" or not but it goes onto the axel spindle. I don't remember the Nissan CD telling me to grease anything but I may have missed it. What do you guys think?

Thanks,

Did you check the tires???? I had a problem in the car and it was the tires...

 

Good question. I have Traction T/As on the back currently. Front tires are new and car is in alignment. When my tractions (currently in the rear) were on the front the car had a toe alignment problem (tires canted / \). I have looked at the tires and they seem ok but I guess it could be the tires. They still have decent tread so I do not want to ditch them (spent 150 a tire). They are also a harder compund tires so I guess it could be causing the noise. It just seems like it is more of a harder material sound at times. Almost sounds like I have one studded tire in the rear.

Another thing to mention is the sound is between the average bearing revolution sound : wooo, wooo, wooo and the studed tire sound wooooooooooo. Know what I mean? It does not have the consistancy of a bearing sound. A bearing sound is so consistant with every wheel revolution you can almost time it with a stop watch.

 

my falkens are getting progressively louder as they have worn..... Generally, performance tires are gonna be louder than A/S or touring tires...

 

it has to be the tires... the constant woooo is the sound of tire warp or whatever the word is.... I had the Potenzas RE040 the Z ones, lasted 6 months... need to replace them.......back to normal Potenzas again... GOD they SUCK big time.... waiting until they go bad to get Continental or something else...

 

I believe it is called radial slap or something to that degree. Is it that bad though. Sometimes the noise/vibration seems too harsh to be radial tire problems. My gut tells me tires are only contributing to the sound/vibrations. I was driving home this morning (3AM) and at 70 MPH the noise/vibrations do NOT EXIST! Weird. Only at certain speeds on certain roads. I know for a fact it is not the road though

yeah if you said the tires looked like that, then they are cupped which will make that ungodly WRRR WWRRR noise or whatever, get some new ones

 

I guess I will have to ride it out for a while until I am ready to get new tires.
