rear wheel bearing replacement

[ricksza]

From what you're describing, it sounds like a balance problem. The vibration in the steering wheel would be the front tires while the vibration in the seat would be the rear. Are you getting the tires spin balanced? When you get the tires balanced again, if you can, watch and see if you have a wobble in one or more of the tires. You might have two problems. If all else fails, try to swap wheels and tires with someone else for a test drive.

ok so the drivetrain cant possibly vibrate the steering wheel then? it feels like a really high speed vibration in the steering wheel, could that be a bearing? cuz i really dont feel it in my butt anymore, im definitely going to get the tires balanced and rotated and if it still does it i will get new tires. any recommendations on a good brand thats cheap? also, i thought all the shops did spin balancing... dont they? its this computerized thing that spins the tires from what i can see... i have them done at wal mart cuz they do a great job. thanks!!!

At this point what you should do is to take it over to the dealer and pay for a 1/2 hour diagnostic (about 30 bux). You keep throwing more and more parts at this thing without succsess.

Where the engine and transmission mount on the frame.

Actually it's a single transmission mount... the mount pad is on the cross member going underneath the tranny.

Yes, that could cause the vibration.

Could be a broken belt in a tire...I had the samething happen to another car i owned and it was a single broken blet in the tire..

yea well vibration is back, and its now a bad humming between 65 and 75mph. i get to 43mph and i can hear the "resonating" throughout the truck, the 50mph comes and i feel it in the wheel and just gets worse up to 75mph, which is as high as i have gone, and at those speeds it feels like i am getting a massage through the steering wheel, thats how high speed the vibration is. the 65-75mph humming is bad though, im concerned now that something is really wrong. i never did get to replace that passenger side engine mount when i got the drivers side mount done, maybe both mounts are bad again? any ideas here? i am really tired of paying on this truck every month and it still not being right... i always thought blazers werent supposed to ride like shit all the time, especially a 2000 with less than 100,000 miles on it!

Check to see that the bolts on the new motor mount didn't come loose...Did you put them in or did a mechanic?

the mount was installed by a gm tech at the dealership.

I would take it back then and have them check it again under warranty. That way it won't cost you anything.

i didnt know i had a warranty...
