I have a 2007 Tundra DC 4WD. Had severe bounce only on the concrete freeways…smooth as glass on asphalt. Bought a $1500 SnugTop shell weighing about 300 lbs…Problem solved! And the truck looks awsome with the shell too. Mounting metal plates under the rear frame in the C channels also sounds like a good fix, since the bounce is caused by Toyota’s new trapezoidal frame design, which is designed to flex. Unfortunately Toyota didn’t consider the concrete freeways in many states in the US. The problem is the resonance frequency of the trapezoidal frame matches that of the expansion joints on many concrete freeways at freeway speeds (55-75mph). Actually, I didn’t really solve my bounce problem, I simply changed that resonance frequency with the weight of the shell. So now my truck doesn’t bounce on concrete freeways at freeway speeds, but it does still bounces at slower speeds (about 35-45mph). However, I rarely travel that slow on the freeways. By the way, they (CalTrans I guess), grinded down about a ten mile stretch of one of the concrete freeways I live near, which was one of the worst…like a washboard. Now it is as smooth as glass, at all speeds. WOW, what a difference! They need to grind down all concrete freeways.

Jason finally got truck fixed. Over $10,000 worth. A set back was the new condenser put in had a hole in it. Took 24 days to fix and I had to put it in today to replace the tensioner and belt. Tensioner was bent and the belt had pits in it fron trying to turn when the fan went through the radiator. Today was a $400 bill. I do have to give credit to Superior Toyota in Parkersburg, WV not for just fixing, but steeping up today and used their dealers credit card to pay for what I had fixed today and will get paid back by Allstate. I do have a bit of advice given to me by the manger of the body shop. He said I reacted right but I hit the brakes hard when the deer jumped in front. That caused the front end to dive down which in turn caused more damage than if I would have hit the deer straight on with my foot just off the gas. The bumper would have taken the brunt of the force and way less damage would have happened. I can see his reasoning on that. Glad for insurance.

Jimmy I have an Hellwig sway bar on my 07 Crewmax. Great on cornering. I don’t have the bounce either but I just wanted to try it and see how it goes. It has 3 settings also for a firmer ride.

Just wondering if anyone has tried the TRD rear sway bar? I have a 07 Tundra DC longbed 5.7 4×4 and have had no bed bounce problems. But I do use it for work and keep it loaded.

Good to see a constuctive post for a change.

Willy bar how appropriate is that name?

I’m going to have the plate steel cut and mount it to the frame rails above the rear axle, just need to find the time beween day care for the wife (no Joke) and hunting.

Drove from South Orange County to Camarillo (Ventura County) to have my WillyBar installed this past week-end. This route (the 405/101) is on some of the worse cement freeways in California. There is a definite improvement in the ride of my 07 DC. The bounce improvement is at least 50% and the truck now basically rides like most other trucks I have owned.. The weight added is 300 lbs. I have yet to determine the effect on mileage. I will say that with the WillyBar the weight stays in the same place in the bed all the time. I tried cement bags and they kept moving around plus you cannot wash the truck without removing them. None of this applies to the WillyBar and while it is not a 100% fix, at least roads that used to spill my coffee no longer do. I am still ticked about having to invest another $500 to cure a basic engineering deficiency of Toyota’s on a $38K truck but with Toyota’s famous customer service on this issue, I saw no alternative but go forward with the investment. One of my friends even commented yesterday how the truck now rides basically like his Camry! I am not sure about that. I will be changing tires very shortly and am moving from BFGs to Michelins which I am hoping will further reduce the bounce, even if just a little. All in all, the WillyBar, for me, was definitely worth the investment.

Jason I have pics to upload if you want to see them. Saturday while traveling up from Florida to visit in-laws by Pittsburg I hit a 7 point buck about 100 - 120lbs. I was on I-77 north near Parkersburg, WVA. Got $7,000 damage to front of the truck. No one hurt but I didn’t kill the buck. I was doing 70 when I saw him and slowed to 35mph when i hit him. The sheriff had to put it down. Good thing we didn’t take the Prius or I hate the worse could have happened. BTW I was getting 17.7mpg in the mountains at 70mph.
