Default '89 LE - Constant Velocity Shaft NOISES

Hey Guys...

slight problem here...it seems to be getting pregressively worse...

I am not sure, but i think i posted about this issue before...

i am not sure that it is the CVS...but when the car is going about 29-35 MPH there is this humming/vibrating/whurring sound coming from the left front wheel...i can feel a vibration on the driver floor...

i was under her today completing another task and was looking at the CV shafts, they looked fine so i decided to do the wiggle test...
passenger side, no wiggle...driver side, kinda a knock wiggle like the feeling when a hub has bad bearings...now just to clarify, this play is where the shaft comes out of the the trans, NOT BY THE WHEEL...

i would take a video of it, but i dont think that the camera would pick up the sounds....

also, more specifically...say i am going down the road at about 20-35...ok, well if i just **** the week just SLIGHTLY to the right...that is when the most noise comes out...but if i knock the wheel just slightly back to the left...ALL QUIET AGAIN...i am so confused...i wish there were some more members in my area that would help me diagnose this....

ok so, now, how long can i wait till this gets critical and how much is it gonna cost?

Thanks!

That sounds much more like a wheel bearing than an axle issue.

Not being one of my strongest areas, hang in for the others to give more insight.

Wheel bearing. When the wieght shifts to the upper race thats where the noise comes from. Its probably scored.

i have been being ultra easy on the accellerations...i guess i don't have to be

no its just that when i just start it, and put it in gear and press the accelerator, i feel a kinda slip, grind and clunk then everything is fine....

ok now...good, we have established that it is most likely a wheel bearing and not a CV.

ok so, what is the best kind to get, where to get the best ones, and what is a good price? and also, how long can i drive i like this?

Check for play in the bearing before you replace what you think is a bad bearing. this is done by jacking, or suspending the tire, and wiggling it.. If there is alot of movement, then yeah, its gotta be the bearing. especially if its making that noise!! sometimes, the bearing can be noisy, but no play.. but this would be for quiet bearings thougn.. before wear occurs.

ok guys, tell me, the parts store says that wheel bearings should always be replaced in pairs...is that required or just recommended? They are $70 EACH, so yeah, not a whole lot of money...

i never replaced in pairs on my bonne. just replace the bad one and be done with it, its an extremeley easy job. axle nut comes off, 3 bolts on wheel bearing, pull bearing off, replace the little seal thing, and put new bearing on, reinstall bolts and viola, done.

I'm hearing two different descriptions of the noise. Skip, grind ,clunk is diff from groaning noise in turns.
