Whining/whirring sound from rear end....OMG.

So, the day after we sold our truck (so no spare vehicle), I noticed a sound from the rear while driving, which likely started a while ago but I just thought it was winter tire road noise. Sort of a slow pitched whine or whirring sound that increases the faster you go to a certain speed and then it sort of levels off, and is noticeable again on deceleration. Hubby suggested it might be a rear end diff problem, and I called our cheap young mechanic here, and made arrangements to have him jack it up and listen to it on Monday. He said it could be just something like a wheel bearing, and if it is the diff, it could be costly to fix although he would get a used one. We were going to start looking for a new vehicle this week, now that we have the cash from selling our truck! I hate to spend a bunch of money on it at this point, and I guess I could just fire sale it as is, and try and find something to drive nearby.
Anyone had something similar happen? How risky is it to drive? :cry:

Possibly the rear differential . Could be bone dry and fresh new fluid is needed. IF that is the case, you might luck out and no internal damage, might get away with your mechanic adding fluid and everything fine. This problem you are having now is exactly why i got my mechanic to check my rear differential on a hunch. Sure enough it was near dry. Got that and the transfer case looked at and new fluids. That was in 2018 and everything runs perfect on my 06 Xtrail awd. Diagnosing Differential Noise | Know Your Parts

X-trails are notorious for eating wheel bearings. While you're driving down the road in a safe spot turn the wheel sharply to the right. If it gets louder it's the left bearing. When you turn left and it gets louder it's the right bearing. When you turn sharply it loads the bearing on the opposite side and the volume increases.

have you had your wheel bearing(s) replaced previously? if so, what did you experience leading up to it and how much should i expect to pay to replace one, parts and labour? Any preventative maintenance i could do at home or is it a pain in the butt to self service?
