Today was my second trip to the dealership for this problem in the past 3 months.
My warranty is up in another 2000 miles.
Hope I don't have to change these everytime I change my oil.
This could get expensive once it's no longer under warranty.

 

Had 5 Maximas and never a wheel bearing???

 

front bearings or rear? if it's front, then I would check the ground cable coming from chassis to the enginge.

 

No, but you could have a bad rotor that you just dont feel. Certainly the vibration would kill it, especially if you've replaced the bearings more than once.

 

What would a ground (Electrical) have to do with bearings failing? (Mechanical)

Your statement makes no sense.

 

if you have a bad ground or no ground going to the engine, the current will try to pass thru things like axles and bearings to get from the chassis to the engine. Thus over a period of time it will ruin them. He might not have this problem, because this takes time, but a very simple thing to check on.

 

That's just nonsense!

 

my thoughts exactly.....

hypothetically speaking, if that's the case then the brakes would have fried, all the wheel bearings would have fried, the drive shafts, transmission, etc., etc..... heck your whole vehicle would be undrivable, since your keyhole, shifter, brake and gas pedal would be "electrically" locked.

Bottom line, an electrical shortage cannot affect a mechanical component such as a bearing (non-driven, free-floating)...

I don't like flaming people, but sometimes when common sense isn't used, you are gonna get it....

 

also, did you have aftermarket wheels that where the right offset? Did you get an alignment occasionally? 'cause that could also contribute

 

1st time it was for the front psgr wheel bearing...
2nd time it was for the rear bearing...
I have stock 2002 GLE's on the car...
And havent gotten an alignment yet, doesnt seem to need one...
I have 33.5k miles on the car...

....and i don't think its a bad ground.

 

I'm just thinking heat or vibration. I've heard of dragging brakes doing it.

 

ive toasted both sides only once. i thought it was from burnouts but i stop doing that and the other side went too. just natural wear i think.

 

My rear passenger side wheel bearing went to sh*t at 36K
So far so good since I got it replaced and I'm about 4K in.

 

Umm that is a LOAD OF CRAP. Please do not give false information on here again.

 

No, no people, its not a total load of crap. Its not applicable to our cars, but some large vechicles, like constuction equipment can have problems with grounding and bearings. Also can happen in aviation where static discharge and lightning strikes can spot weld a bearing race.

And since some tires are still steel belted radials, you can carry current to the ground, can happen with lighting or very high voltages, again with industrial equipment.. but I wouldnt think a max.

 

We are a large metro dealer and we are not seeing any patterns of this problem. Did the noise go away when they changed the last bearing? Did they change one side or both sides? Please e-mail me at todd@raybrandtnissan.net with the answers to these questions and I will give you more information.

 

have you had an opportunity to look at the wheel bearings? was the grease dirty? How are the bearings, they look 'tore up'? Did it seize? What's happening?

how do you know it's the wheel bearings?


about the electrical problem blowing wheel bearings... it's probable, but VERY VERY unlikely. His ABS sensors would fry before the wheel bearing...

 

Have you had any tranny work done on the car? When the tranny is out, the dealer MUST install and torque the CV shaft BEFORE they roll it anywhere. If not, the bearing will develop a small PIT, and get very loud over time.

goto www.motorvate.ca and click on Steering & Suspension, have a look at my wheel bearing.

Take Care,
