Question what are the symptoms of a rear end going out?

HI, I was wondering if anyone knew what the symptoms of a rear end pinion gear problem is, Is it when accelerating that a pinion gear in the rear end will whine/ make a noise or is it when you decelerate and let your foot off the gas that a rear end will howl??

both really ive had afreind who his 9inch would only wine wile he was in the gas, and my pops truck would have a low rumble when he lifted but not when he was in the gas. what year is ur car? and what rear end is it? also it can be a sighn of a bad install, did you just get the car? or install new gears? its not to hard to take the cover off and if you have hi miles it wouldnt be shuch a bad idea to change the oil so that gives ya a reason to check um out.

cams, and all basic bolt ons, arizen seats, cowl hood, and now my buckets got a hole in it (meaning im broke) but when i fix it ill have gears and some trany work

rear ends aint my game, but try changing the rear end fluid. be sure to add lucas! i dont know how much but read it and follow it, it it says up to 60% capacity, then put 60% in there... the fluid u have now could just be old, and watery substance from being so old...

The above are some good suggestions, although I'm not usually a fan of additives and I don't think they're really needed unless they're called out for.

At least check your gear oil and top it up if needed. Make sure it has the proper friction modifier if you have a limited slip.
