Rear end howling, Weird symptoms
ok, so I have a 90 lx 5.0 notch, anyways the rear is howling when driving, noise STOPS when i use the brakes, so I ran it with out with drums on and the noise is still there, But when i hit the brakes the noise goes away. Absolutely no play left to right on the wheel bearing, and noise is pretty constant while accelerating or de accelerating what do you think

It's simple with an impact gun but also a bit out of "the proper procedure."
Remove the driveshaft. This exposes the pinion nut bolt. Mark it with paint or a Sharpie. Hit the nut with the impact gun for a few quick blasts.
If the noise comes and goes with the application of brakes. I'm thinking it's not the pinion nut.
I've a couple times on 8.8 but they are also known for wearing out the hardened finish on the axle shafts where the outer bearings ride on them.

You need to have someone ride in the back of the car to diagnose the area that the noise seems to be coming from. I always suggest to go at the simple things first. Check your rear end fluid as well. I would strongly suggest you diagnose ASAP as you don't want to have a wheel bearing seize while your driving (not good). Have you done any work on the rear end, if so someone will need to check your gears as the lash may not be have been set properly. If its the gear settings, how long have you been driving like this? Ain't no feeler gauge gonna fix worn gears, have that checked as well! let me know how you make out! If all else fails turn up the radio!

well, i opened the cover today, and the bearings look fine no metal shavings or anything abnormal, no bluing on the metal, everything is fine there, wheel bearing has no play what so ever, it still howls until i press the brakes, I added friction modifier and 2 and a half bottles of gear oil... still howls, it will pose every time and there is no clunking, drive shaft is stable and all bearings seem to be like new...what the hell could it be this is really irritating, not the pinion bearing, nor the axle bearing..could it be in the brakes?
