So my rear axle basically snapped last week, the passenger side arm that bold to frame snapped off. I got an axle from a 96 I30 at the local pick a part and put it on, after about 3-4 miles of driving it starting vibrating or humming and if i pressed brakes it stopped and it also stopped on its own. Its random tho, it comes and goes and probably only does it less then 5% of the time. I think it may be the bearings because the axle sat in the JY for a while and maybe dried up. I also replaced rear calipers and shocks while i had it all apart.

Any thoughts?

 

Did you spin the hub to check if it was smooth before you loaded it with brake components? That would have made it easy to detect a bad bearing.
Being it stops when you step on the brakes might also point to the brakes as the cause.

 

Ya it spun just fine before I put it all together, I was thinking when you apply the brakes the car tilts forward just a little and takes weight off the rear end making it stop. I was ruining about swapping out the bearings with the ones off my old axle just to see before I bought new ones.

 

Dang phone, thinking not ruining

 

His much did the junkyard charge u if u don't mind me Askin...I'm about to replace mine cuz I think its bent..( toe issues) . And was it a beotch to pull in a jy?

 

It was a pick a part or whatever and it was only
$60 and I actually pulled 2. I pulled one off a maxima that had rust on it, took me 90 min, then I was coming back with a wheel barrow I passed an I30 that had a clean axle and I pulled that one in 30 min. It was actually easy, cars are lifted up, and the wheels are off. I also found a seat out of a different car and sat on it and floor mats to lay on. Also a tip, break loose all the big bolts first, much easier then trying to break them loose when its loose and hanging there. I also brought my little 12v drill with a 3/8ths bit so after I broke stuff loose I was able to zip them off.

I can't figure out tho if my vibrating is coming from my brakes or bearings, it does it low speeds and around 30-40 mph and with how loud it is at under 5mph I can't see the bearing doing that. I think maybe the axle breaking and the e brake getting yanked maybe tweaked my rotor.
