low rumbling sound
 

I have a 1995 200SX. Someone hit my car on the right side near the rear bumper and ever since then it has been making this really low rumbling sound when I go over 20mph. It sounds like an airplane roar or a growl. It gets progressively louder the faster I go, but it sounds the same even when it's in neutral. When I brought it in to get fixed they thought it was the axle vibrating because it was slightly bent, so they gave me a new axle but it didn't fix the problem at all. It doesn't sound good. What could it be? Please help!

Thanks

Did they replace the bearings when they replaced the axle? I'm no expert, but the rumbling sounds like a bearing issue.

Yes, that's exactly what it was. It was the rear bearing. Thank you
