Yes, they replace the tires/wheel with another new Tahoe but had the same problem.
I got a call Saturday (27th) that it was ready to be picked up and problem was fixed. They replaces the Ring gear in the differential. They drove it and said it was fixed. I picked it up and drove maybe a mile and knew it wasn't fixed. I took it back to them Sunday. They called again today to say the ring gear is out of round again. OMG-- I can't take too much more of this crazy stuff.

I can't beleive no one is looking at the Rack & Pinon steering as a potential problem. I have a county vehicle in my shop. Vibrates when slowing at highway speeds, not brakes, not tires-wheels. Looks like a design flaw to me. This vehicle is too heavy for the Rack & pinon design. The bushing are too soft, and over time, it allows for side to side movement of the entire rack & pinon unit. I can see after about 30K miles how it would start to vibrate just like a bad tire, even when not braking. Problem is with the bushing design, even with a new one, the same thing would happen after same miles. Design Flaw in my opinion. Rack & Pinon is for cars-not trucks.

They were actually saying there is a problem with the rack and pinon as part of the problem. But they don't know if it's actually causing the ring gear to get out of round. Which in turn causing the vibration. They are waiting on GM to tell them what to do next. Everything is on hold until then. But I've already filled out the Lemon Law paper work, when I go in to talk to the Sales Manager tomorrow and don't get the answers I'm looking for then I will go to the post office. But I don't think I want another Tahoe if it's going to have the same problem. Do all of them have rack and pinion steering? I would assume so.

I only have 3000 miles on my Tahoe...
#50 of 198 New '09 Avalanche 2wd Z71 shakes too...
Apr 25, 2010 (9:43 am)
Interesting to see similar "shakes" in other new Tahoes, Suburbans, etc. like my new Avalanche.
Bought a new '09 Avalanche (last to be built for the model year, 10/09) on the last day of February '10. Almost 2 months now, 2700 miles (first 700 from the dealer in Georgia delivering it to me). 2wd Z71 model with the "off road" bits, 265/65/18 Bridgestone Dueler A/T RH-s tires, 6-spd trans and 3.08 rear axle.
Has shuddering/vibrating quiver where the seat shakes, steering wheel vibrates and floor quivers cruising and accelerating. Random at times in how bad, once in a while will just go smooth. Cross truck shudder & quiver, cruising and accelerating, especially when warm/hot out.
Did it from new, but I couldn't figure out what it was. Drove a new leftover '09 4wd 1LT with the factory 20's and 3.42 rear before, it was dead smooth. No vibration, just smooth and solid. Drove a '10 2wd Z71 with the 3.42 before signing for mine, since mine was coming from so far away & I had never actually driven a Z71, and it was softer than the 1LT with a bit of flat spotted tire shake for a couple miles, then smooth. Just a little luggier feeling than the 1LT & 20's, because of the A/T 18" tires, as expected.
Mine does this:
-"Quivering" feeling driving even at really low speeds, feel it in the seat and wheel
-Vibration through the seat and wheel continue up to speed, worst generally from 35-55 and can get a little less if faster
-When warm out, sunny, etc. and the tire pressures bump up, it shakes worst...oddly, on night trips, it's turned smooth or smoother for no real reason, cooler roads aside
-Any kind of texture to the road makes for a constant quiver throughout the truck, still there on perfectly smooth roads but not as much; driving through my development at 25'ish, it quivers
-Warm/hot days when shaking, it'll studder to the side and wobble over bumps...maybe just the A/T tires, but more pronounced at times
-Some days, not cold but not hot, and raining/wet it'll be smooth...or at least smoother than otherwise
-On the days that the vibration in general is really noticeable, shakes badly when accelerating from a stop too
-Shuddering is V4/V8 mode regardless, and the truck idles and revs like butter--not even a vibe at idle. Just had the ECM/TCM custom tuned (performance, better shifting, etc.), and no change in the shaking whatsoever
What's been done:
1) Dealer tech drove, felt vibration, road forced all tires & said they were out of balance; said it still had a vibration afterwards but to drive it since it was still new, and see "sometimes those tires get like that if they sit a while"; for the most part, it was the same or worse after they balanced them.
2) Not believing the dealer, I took it to an actual Bridgestone dealer locally who was glad to help. Knew every possibility. Day I drove it to them in the rain and 50 degree temps, it didn't vibrate a bit and was SMOOTH. Of course. They road forced all the wheel/tire combos too, and said they were actually some of the best assemblies they'd seen and were true & in balance. Said it could either be something with the truck or maybe just the feel of A/T tires on a luxury SUV.
3) Back to the dealer last week, but of course the truck got SMOOTH the same day, for no reason. Couldn't even make it shake. Explained this, but what it also does most often when warmed up & they noted it. End of day, got a call a tech had driven it 25 miles "but didn't feel anything'. Of course. Still felt smooth when I picked it up, like in the morning, but after about 5 miles of errands & heading home in on a warm, sunny afternoon, the shakes were back, not the worst but still there. The next morning, same roads, same temps, it vibrated like crazy first like a switch had been flipped, steering wheel shaking, seat shaking, the bad cross truck shudder on perfectly smooth roads turned back on. Sad to stop in next time I'm out, it's shaking, and they're open. Trying...
It's weird because it always shudders, but some days can go from barely to really bad. Usually just always the constant light to aggravating quiver & shudder that comes through the seat, wheel and floor. Our '02 Z66 and '04 Suburban before never had a single vibration issue at any speed from day one, and I didn't notice anything in either of the other 2 new Av's I drove, or any other GMT-900 Yukon's, etc. I drove before.
The fact that it's worst when hot and the tire pressures bump makes me think tires, as does the smoother rain drives. But 2 road force jobs, including one from a very helpful Bridgestone dealer, and it still shakes slow, accelerating, or cruising.
1) Tires/wheels. Still likely. But on/off/sorta random-ness? Still possible. These Bridgestone Dueler A/T RH-S tires in this size are on an eon bazillion of these trucks, but I have yet to find any reported number of issues. 1 or 2 here or there, complaining of them throwing rocks all over, but not vibration issues.
2) Drivetrain? Runs like butter, still, doesn't hesitate, doesn't even give off any vibes at idle. If the driveshaft were out of balance, a U-joint, etc. with issues, I wouldn't think there'd be the random shakes, doesn't shake, sorta shakes, smooth as silk, my hands are going to fall off shakes...weird. I know the 6L80E from my G8 GT well, not a normal trans issue. Truck is now tuned, ECM and TCM, and not a single change in the shaking.
3) Smoother at night after sitting sometimes? Again, weird...
I'm about to just pay for new tires and go from there. Hoping for a good shaky soon with time to stop in at the dealer & give an impromptu ride, but we'll see.

Well after a whole new rear end and 2.5 weeks later...it still vibrate between 45-55 mph. Just called the East Coast Rep for Chevrolet and they want me to bring it back to the dealer for them to ride with me. New tire will not help. I just talk with a Bridgestone tire dealer yesterday and said that it has been done before and it's not the tires. He was very helpful and drove it himself. I'm at my wits end, can't believe a vehicle of the price would have such problems. Chevrolet doesn't not know what causes it. But I'm with you the vibration frequency (amount of) depends on the time of day. Mornings going to work is the worst case. Thanks for your input beach15.

been there - took me more than two months and over 10K miles to fix my problem - at the end of the day and after going to arbritration which I lost vs. GM all it took was changing deaerships - took the truck to a dealer much further away and it payed off - suggest you try the same - some dealers dont have the mechanics that can work these issues - youcan always call and find out - Grand Prize Auto in Miami - the problem has vanished ..... happy again - think it had to do with the drive shaft after alll - good luck

have them check the rack and pinon - just remembered that in my truck it had to be replaced a month after the vibration problem was fixed - not sure how the vibration ws fixed and the problem went way but then trouble with rack and pinon happen so you might as well have them take a look at that - read a blog in this group that talks about the rack and pinon being the cause and it does make sense

I did not face this problem in my Tahoe 2008, but i faced it in Tahoe 2009,, anyway, after six times checking it in Garage, they eventually confessed that the problem of this vibration is from Drive Shaft, they fix it and it is very good now.
