Re: Vibration around 50 mph? Updated poll inside.

You sure sound like you know what you're doing. Too bad you've had this bad experience with your Malibu. And, the bad experiences you've had with dealers. I'm actually suspicious of the GM dealer where I bought the '12 Malibu. But, my Chevy dealer a quarter mile down the road where I bought the '09 and where I've bought two PU trucks is fairly stellar. I've had a couple minor problems and both times the dealership owner or his brother have responded very well. Apparently they are serious about keeping an "excellent" rating with Chevy/GM. Again, I sure hope you somehow get the clicking sound remedied.

Re: Vibration around 50 mph? Updated poll inside.

just curious as to how many of you with the vibration have cleaned your wheel hubs? i mean, it requires disassembling your brakes, but it can really help tough to solve vibration issues.

as for my story, when i bought my car, i had a really annoying vibration around 70mph. new tires fixed a lot of it, but it was still there.

last week, i put on new rear brakes so i had everything apart anyway. i took my drill with a wire brush and went to town. cleaned off almost all of the rust. my vibration is now 90% gone. i still have to do the front, but im incredibly happy with the results so far.

just something to look at before jumping into more intensive fixes.

Re: Vibration around 50 mph? Updated poll inside.

My '11 V6 LTZ has started dong this at 44K miles. New tires all the way around, balanced twice, 4 wheel alignment done, which really didn't need to be done as it was "dead nuts on" according to the tech who did it. Also replaced brakes and rotors all the was around to no avail.

I agree it not wheels or alignment its transmission.

Some days its really bad, some days its not there at all.
I tried a little experiment the other day coming home. I held it in manual mode coming up about a 3/4 mile grade (as I always do because the trans programming on this thing really sucks), and holding between 60 and 70 in 5th gear the vibration was BAD. As soon as I back off the throttle, it almost completely goes away. The next day, same circumstances, no vibration at all.

I've also always noticed that this trans has a slight shudder in 3rd gear during mild acceleration, just momentarily, by I can tell what gear its in by the shudder. On hard acceleration however, it won't do it.

Makes me a little nervous considering I bought it used, it now has 45K on it and this issue has just started in the last 4 months.

Re: Vibration around 50 mph? Updated poll inside.

I'm on my 3rd Gen7 and all have had the 3.6L V6. Very happy overall, but ...

My first was an '09 2LT and I did not have the vibration at any time while I had it. I bought it with 1052 miles on it and the dealership called it "new" since it was an out-of-state dealer-trade. I added 19K miles and traded it at 20,058 miles.

My second was an '11 LTZ and it had only a slight vibration every now and then. It was not enough to bother me or to do anything about, but the few times it happened I recall it being between 60-70 MPH. I bought it new (9 miles) and lost it to a flood at 44K miles.

My third is another '11 LTZ that I bought with 56K miles. It has had the vibration more than I'd like but, again, not enough to do something about. It has always been between 60-70 mph as well.

Well, around 83K I lowered my car. When installing one of the front struts the half shaft had moved outward far enough that it was no longer on the output splines in the transmission. I spun the wheel slightly while pushing inward and got it to go back onto the splines. I'm not sure that that had anything to do with my current condition, but my car now vibrates slightly between 60-70 mph quite often. When I'm in 2nd or 3rd gear accelerating from 20-30 mph it vibrates quite noticeably. I can reproduce the vibration from 20-30 anytime I want, but thankfully the vibration from 60-70 is less and somewhat random.

I believe the vibration is related to the transmission to some degree, but it also seems to be related to the half shaft's angle relative to the transmission. It could be the CV joint is a little out of spec, or the outer diameter of the inner housing is off, or the output shaft's splines and the internal splines of the half shaft don't mate well enough and they set up a small vibration.

The latter is what I would consider the best theory, but it's just a theory. To test it I'd have to loosen the strut enough to pull the wheel outward, spin it, and reinstall it. This would align the splines differently in relation to each other and might take up any slack in them, or add more and make it worse.

Re: Vibration around 50 mph? Updated poll inside.

My thoughts on this after having the axle shafts and engine realigned per the service bulletin and having the vibration slowly come back are:

I believe the culprit is the intermediate shaft bearing. In order to quell FWD torque steer, the Malibu has equal length CV shafts on each side. For the right/passenger side there is a long fixed intermediate driveshaft with a bearing at the end bolted to the back of the engine, very similar to a carrier bearing on a RWD driveshaft. This allows the cv shafts to be a similar length and reduces torque steer. But a bearing can and will go bad. Has anybody here had this part replaced in concern with the vibration problems we are having?

Also, the 4 speed trans does not have this shaft-and most of those people report not having vibration issues.

Re: Vibration around 50 mph? Updated poll inside.

not sure if this is related but after speaking to a mechanic friend he suggested pulling the abs fuse and driving the vehicle on the highway to see if when braking the vibration would go away. (note i did replace the brake pads rotor and caliper) the problem immediately went away. I am going to pull the wheel and disconnect the sensor to make sure the problem is actually the abs is the root of the cause, and will update further. if this is the problem and incase you are wondering i will have to replace the entire wheel hub assembly since there is no way to just replace the abs part.

Re: Vibration around 50 mph? Updated poll inside.

Our Malibu vibrated quite a bit when we first got it. A little bit on the take off and some at speed 60-75mph range depending on the road type. The car had been through 2 passenger tie rods ends and 2 alignments and since it was used the dealer was not going to spend much time on the issue. Fast forward a year and the inspection (at my friends shop) finds the driver lower control are ball joint shot. He allowed me to replace it myself, so when I mean shot the ball joint friction was non-exsitent. On most cards with a ball joint that bad you can hardly drive it. I didn't feel anything that would lead me to believe it was bad let alone this bad. So after a new control arm and an alignment (we found it to be way out even though it had be aligned the year before), the vibration at speed is gone and the take off vibration is almost gone. Made a huge difference in the way it drives.

My vehicle had started vibrating after getting tires changed but that was because they hadn't been balanced correctly. Had the tires re-balanced and the issue was resolved.
