For the last month I have been hearing a hum from my rear suspension. It sounds like it was coming from the passenger side so I replaced that side's hub but the hum is still there. Any ideas on what could do this? I thought maybe a bushing or the strut. Any ideas would help I am going to put it up on a lift this weekend so that I can inspect everything but I don't want to start tearing the entire rear suspension apart.

did you replace the wheel bearing with the hub? otherwise the wheel bearing might need some more grease

I put the one that I bought from you Lewfx on there and everything was fine. I drove to Montana and then over to Washington and on the way to Washington it started to hum. I thought it was the bearing but like I said I replaced it and the hum is still there.

how quickly i forget...tire pressue okay?

check the alignment, TOE can cause some hard to find noises that sound like bearing humm.

I have no odd tire wear and since it started I have driven about 3k miles. I'm thinking that it might be a strut or a bushing.

id take a looksy but you seem far from torrance.

toe in or toe out can be very hard to feel, just a degree out of specs can cause noise with some tires.

strut wont cuz humming.
