ABS sensor in rear bearing replacement 2014 Forester.

[farmer]

I'm replacing the rear hub on a 2014 Forester.  The bearings were getting noisy on that corner.

 

This one has ABS.  Should the sensor be removed before taking out the hub?

 

Thanks a lot.

Not sure if it's required

 

Tbh, if it isn't frozen in there, taking it out is just a better, safer option. If you leave it in, you risk damaging it. Even if it doesn't require removal.

 

But a wheel bearing going bad on a 3 year old car? Already?

Thanks for the response.  I'll go ahead and take it out to be safe.

 

It's got about 85K.  Just started making noise.

Changed the bearing/hub and took care of the problem.  The noise was a low level whirring noise for those diagnosing something similar.

 

Not sure why wheel bearings on these would be a problem, but in Googling it seems to show up a lot. 

 

I would say if you plan on changing a wheel hub on these I would shoot some PT Blaster in the back of the mount a couple of times and days before the change out.  That would be around the perimeter of the outboard CV.  (I wouldn't get it on the CV boot, but I'm not sure it would make any difference.)

 

If there's rust in there the hub case may come out hard and the penetrating oil will make a lot of difference.

Was it the right rear bearing?  The theory is the camber of the road side-loads the bearing, and it doesn't like it much.

This was the left one.
