I replaced both rear wheel bearings at about 30k miles. After 15k miles, driver side bearing became wobbly. I swapped it again. Now, 10k miles later, my wheel has play, same symptoms as before.
What would cause premature bearing failure?

Assuming you are pressing them on the hub correctly and using a quality bearing, ts your axle nut/halfshalft coming loose. You need to 1)clean the splines on the halfshaft to make sure its seats all the way 2)make sure the threads and nut are completely dry, and finally 3)torque the axle nut to the max spec preferably with an impact followed with a wrench to verify torque.

It would be quite difficult to over-torque that particular nut

What offset are you running?

And, where are you getting the bearings?

I might add if you're installing aftermarket bearings they won't have the same lifespan as a factory...


For the most part.

One point to emphasize: torque the 32 mm axle nut to 156 ft/lbs and check it to make sure it stays tight. I've used blue Loctite on mine (along with the cotter pin) to ensure it stays tight.

Stock wheels.


Thank you. It appears to be the bearing this time

I do torque it down. I think I did 160lbs last time.


Last one I got was from rockauto. Don't remember the brand, it it was Japanese made. What do you recommend?

OEM Nissan.

Timken BM500006 Bearing Module on Amazon for $50.

Looks like they make the Nissan OEM bearing. Is that correct?

Probably, they make most oem.

With loctite, if that thing needs to come off in 5 years it is going to be a nightmare.

I have read this all over the internet, but with my own eyes only seen NTN stamped on OEM bearings I removed. Seen SKF on other bearings like the pinion and diff bearings. Though for replacements I have used Timken for front and rear with decent results.

This. First time I found the rear passenger hub loose and found the nut was not tight. A few months ago i found both rear wheels had alittle play in them. I started searching how to replace the bearings and almost ordered oem ones.

But before I did I check both 32mm nuts. I used a impact gun first then a breaker bar with a pipe on it. Never had noise or issues since.
