2008 CX-9 Wheel Bearing Warranty

[bmlocal175]

My wife's CX-9 had a passenger wheel bearing go bad a few months ago and we took it to a local shop. I think it was 200 something to fix and then the shop couldn't get the ABS sensor cable or something off without breaking it and it was another 100 or so.

Well fast forward to now and I noticed the driver side getting loud. After doing some research on it over the internet I have learned it is covered under the drive train warranty which we are still good to use. We just got back from the dealer and it was in fact bad and they fixed it under the warranty.

My question is: Is there anyway we can get reimbursed for the work we had done on the passenger side wheel bearing? I wish I would of checked beforehand but didn't realize it was covered under warranty.

I have a 2008 Mazda CX9. I have 110,000 miles and have just replaced my fifth wheel bearing. The drivers side has had the wheel bearing done three times. Passenger rear and passenger front once each. Two of these were done under warranty. Has anyone experienced this issue also?

bmlocal 175, welcome to the forum. I don't think you are likely to get reimbursed.
janine, welcome to the forum. There are several members on this forum who have experienced bad wheel bearings.
It has been determined, that a possible cause for the issue is the design of the axle nut a.k.a. hub/bearing nut. This is the large nut you see in the middle when you take the wheel off.
The problem is that Mazda designed it so as to tighten it at the factory to specified torque, then they place a dimple in the nut to hold it secure.
Most manufacturers just drill a hole straight through the whole thing and stick a cotter pin through it so that there is no way the nut can back out.

In any case, the possible cause of some of these wheel bearings might be a loose hub/axle nut which causes the bearing to move back and forth, which causes excessive wear.

However, for people like you janine (and no dis-respect intended), I am of the opinion that if you have replaced 5 wheel bearings, there might be another cause.
I have 54k on my 08' CX-9 and have not had any issues. Many on here have never had issues.
I also do my own brakes, rotate my wheels front to back, etc.
If you have taken your vehicle to a tire shop or somewhere that uses air compressors & impact wrenches/guns, and add minimum wage "technicians" that work at large chain-like stores such as walmart / sams club tire shops, they have no fear of over-tightening your wheel lugs.

I have one tire shop that I trust to do my work if needed who do not use impact guns on the wheels.

Overtightening of the wheels on the car can wreak havoc on wheel bearings. Also, way under-tightening of the wheels may do the same damage.

If my wheels are ever touched anywhere, even at the dealer, I get out my trusty torque wrench when I get home, loosen all the lugs and tighten them to 90 ft-lbs of torque just so that I have peace of mind.

So that's my theory. Either the main nut backing off, or over/under tightening of the wheel lugs, or a combination of the both.

BUY A TORQUE WRENCH. It will be the best investment you will ever make.

Agreed,

You are unlikely to get any sympathy in the form of Money for what is basically not anyone fault, thus the cost lies on the person who owns the truck.. You.

The wheel bearing is unlikely to fail quickly for no reason, as was said, there are several things that you can do to speed up their malfunction/failure.
