Both front or rear can go bad. I feel like front go out more often but I don't know that for sure. Rears are significantly more difficult to replace, and one of the rear axles (C200) has a bearing design that is much more difficult to replace than the other axle (M226).

I wouldn't use Moog, I'd stick Timken or SKF, or buy whatever Nissan sells so that you know you're getting the OEM.

 

On these either F or R could be a suspect. The rears go out if you don't do the diff breather mod (allegedly), and the fronts, at least back when I replaced mine, seemed to be a pretty common issue around 80-100k. For me the indication was grinding when turning and the "brake" light coming on intermittently as I was driving (I think it was the brake/ABS light?). I replaced both front hub assemblies instead of just doing the bearings. For the rears look for differential fluid weeping around the ends of the axle tubes onto your wheels/brakes.

As far as brands go, for the fronts I used Moog as I believe their hub assemblies are part of their "problem solvers" series which address some issues with the OEM parts. What that issue was, I don't remember, but the OEM ones do seem to have some premature failures. Otherwise, I'd have no issue using Timken since they seem to supply a majority of bearings used across numerous industries.

 

Are you able to put it on jacks so you can rotate your wheels to detect play-noise?, thats the only way you'll know for sure. 100% Timken, I just paid 54$ @ Rockauto for a C200 rear bearing, Moog would be at the bottom of my list.

 

If you are driving and go to turn it'll be noisier turning right, meaning front. If bad enough you'll feel in in the steering.

 

We just did that and all signs point to it being the right front. Thanks

 

Well right front tire had terrible feathering on inside and outside. Moved tire to rear noise followed.

 

Turned out passenger rear wheel bearing was bad. Replaced it and spyder gears. Quite now.

 

Nice you did a follow-up, a lot of OPs don't and then everyone's left wondering what the fix was, or did they just bring a lighter and some petrol and have a barbecue.
