the harmonic vibration could possibly be bad harmonic balancer or the wheel bearing are bad even tho the hub assemblies are good

I thought the wheel bearings were located in the hub assembly on my car? I'll check out the harmonic balancer.

yaaa the wheel bearing and hub all in one if you dont torque the axle nut properly the wheel bearings can get loose and make that noise

I've replaced both. According to two different shops, it's the driver side front hub assembly. I've replaced that one TWICE. I'm hoping for a third times the charm, deal. I'm buying from a different place in hopes of getting one that isn't faulty.

12 month warranty. So they'll be getting a returned item, granted the new hub relieves me of this issue.

Well, found out what the problem is! Right hub bearing was completely screwed (how any of us missed that? I dunno, moment of stupidity I suppose). Left outer tie-rod was bad. AND LAST BUT NOT LEAST, the vibration noise was mainly coming from *wait for it* The TRANSMISSION!! Yay for Chassis Ears. Replacement transmission is in my garage, now just for the tedious task of swapping them out.
Edit: Was not the transmission, entirely, however the problem was located IN the transmission. Last edited by Atoms4Piece; 06-16-2012 at 09:41 PM. |

Oh, and the ABS light is on for a solenoid to assembly wire short. I'm gonna have to replace the wire harness between the brake pump and the passenger side hub assembly (which was also part of the culprit behind that noise).

I found the problem. While replacing another CV axle today, I accidentally pulled the output stub shaft with the cv axle. I noticed that it was slightly flattened (I mean SLIGHTLY) instead of rounded all the way around. The output stub shaft seems to be my problem, the question is.... Where the hell do I buy them at?

I have a new half shaft, this piece actually came OUT of the transmission, attached to the end of the old half-shaft. The new one didn't come with one. Here's a photo of the piece. It came off of the end that came out of the transmission. It looks like a sun gear shaft with a bearing on it. I don't know what the piece is and I can't seem to find anything on it...

I can't find the part numbers for either the shaft or the bearing piece around it.

Ok so the thing that I believed to be a bearing (I'm a dummy), is an output shaft seal. I'm still trying to figure out where to find the output stub shaft, though. Honestly, I'm thinking the seal is what is making the noise. It has slight faded grooves on it.

Part of the wiring harness is cut under the car. That's what is throwing the ABS light.
