Now haved 32k on my Tribeca, no chassis vibration, but a wicked, wicket rough ride. Any kind of uneven surface lots of front end noises. Bringing it in for 30k "physical" next week & hope they can correct the problem. Count it be struts, motor mounts,??? Worse car I have had in many years with this problem. Otherwise, very please with car. Gas mileage averaging a little over 20 mpg. Tires holding up real well so far, looks like they may get 50k on them.

Ok, First, I have 54,000 miles on my Tribeca. Other than a few things here or there. Great. I expected it wit the first year model. Now, at about 25,000 miles we started getting a clunking from the front end and it occurred on uneven surfaces. They replaced the struts the tie rod and a few other things. Still did it. The service manager took parts off a new Tribeca and replaced the Tie rod bushings. That did it. But we just hit 54,000 and the clunking is back. This time he's going to order the parts. Also we just changed the brakes and we now need new tires. I've never had a set of brake pads or tires last over 50k before. But we had all our work done by the dealer along with the recommended tire rotation. When you need to replace the tires shop around. When we first got it we hit a curb and cut the side wall. It was 250 at a discount tire store to replace. I just went on Tire rack and found the same tire for 130. All in all, I love my Tribeca and my dealer (Goldstein, Albany NY)

I'll assume you already checked the tire pressures.
 
Probably a bad strut or a broken/damaged spring.
 
At one point Subaru had a recall for the Outback for springs that could rust under certain conditions, but your Tribeca is new so that's doubtful.

yeah, With the sensors going off under 30% I check them often. We had the same thing happen at 25k. But the service manager said it was the tie rod bushings. It only happens on uneven ground. He told me when he repaired it he took them off a new model (2006). In some of the other posts there are similar references to this clunking and all about the same mileage. The funny thing, the one thing they did recall, the hydraulic hatch pistons, don't give me a problem. But I am 6'8" I automatically make sure it is open all the way. But like I said I am thinking about getting another one for my girlfriend. Very happy with the vehicle and very happy with Subaru. I am a Subaru fan for life.

#6 of 39 47mph wobble by morey000

I've only got 5K on my '07 but it has a shudder at 47mph +/-3 mph, which it has has since it was new. It feels similar to a rear tire imbalance. I had them re-balanced at the dealer, but it didn't change the effect. It's possible that the tires need to be checked out on a [Hunter] road force balance machine -which my dealer does not have. Or perhaps an out of round rim? Or an imbalance somewhere in the drive shaft?
 
You can only notice it on smooth roads, so it's not a major vibration, but it IS noticeable. It seems to shudder at the same speed, regardless of gear or RPM, and even while coasting.
 
My service adviser (as is typical) is clueless. Any suggestions on what I should tell him to tell the mechanic to look for?

I have the same issue with the shudder around 47mph, I also get it around 78mph (don't ask). Let me know if you have any luck, I have not. However i do keep bothering them.

Does it get effected by weight in the rear? A friend has a similar problem in his Frontier, but if there is weight in the bed, it goes away.

That certainly makes sense. A vibration is typically caused by something exciting one of the many resonance frequencies of the vehicle. If you add weight, you change (lower) the resonance frequency and it will no longer match what's exciting it.
 
My current status: Dealer tried balancing tires: No effect.
Dealer tried rotating tires: no effect.
Service adviser doesn't know what a road force balance machine is. doesn't understand resonance frequencies, doesn't know if the mechanic has a map of the frequencies and their likely causes, doesn't know if they have an accelerometer setup to measure the frequency.
But... he's friendly.
 
It appears as if I'll be living with this for the next 8 years.

See if you can find some alternate tires. On the Frontier it's looking like it's coming down to the actual tires we have on there. (Balanced and rotated/shifted around at least 4 times so far). These are upgraded tires, with a higher load rating, meaning a stiffer sidewall than stock. When we have a load or trailer on his truck, it goes away, empty bed it comes back. Stock tires and rims, not a problem either.
