The 5.7L is a beast. I test drove one before buying my 4.6L. At this time I just couldn't really justify the need for just under 400hp. My 4.6L sits at 310hp and it is such fun to drive, kind of hard not to drive it like a sports car. It's has not met the break in criteria for towing just yet. I do have a small bass boat to tow out to the lake for fishing, can't wait to see how it tows it.

By already owning Toyota products, you know exacty what you want to buy. You will love the Tundra, especially the 5.7L. If it comes a time where I'll need a little morepower there is no doubt it will be the 5.7L beast.

This is not my first Toyota either, I owned a Tacoma years ago. Found such a great deal on a left over Silverado back in 06 I couldn't pass it up. My son drives a Yaris and the DW drives a Camry.

I tow a 31' 8k# 5th wheel and average 10+ MPG most of the time. My 2008 DC 5.7 does a real good job puling the load with OK milage as long as I keep my speed around 60 mph. The faster I go the more fuel she drinks but with that large front end 12' in the air and 8' wide on the 5r it's expected.

I'm totally satisfied with mine. We have pulled it to north Alabama/Southern Tennessee, and Springfield Missouri from the northern panhandle of Florida. Like has been stated in the above posts, keep it at or under 60 and you will get around 10 MPG. around town, she will pass ANYTHING but a gas station, if you don't drive very conservatively. I can usually get 15-17 in town. Our town is built stop light to stop sign, so don't get into hi gear often.

Update on my '08 Tundra...

...loud roar coming from drive train starting at about 35-40mph. Took it into the Toyota dealer here in Tucson, and found out that the right rear bearing is failing. This at 65k miles. It's going to cost me $1600 for replacement, as I am also having them replace the left side as a preventative measure.

After researching, I found that this is a known problem:

Service Bulletin Number : TSB-0151-10
Date of Bulletin : JUN 11, 2010
NHTSA Item Number : 10034128

Component : POWER TRAIN:AXLE ASSEMBLY:AXLE SHAFT
Summary :
TOYOTA: REAR ALE BEARING ABNORMAL NOISE. SOME VEHICLES MAY EXHIBIT A HOWLING OR GROWLING NOISE FROM THE REAR OF THE VEHICLE THAT INCREASES WITH VEHICLE SPEED. CHANGES HAVE BEEN MADE TO THE REAR AXLE BEARING TO CORRECT THIS CONDITION. *PE

It sure would have been nice if I had known this before my powertrain warranty expired.

Sorry to hear of your mechanical issues. Anytime a service department lay a finger on a vehicle it gets expensive fast. Toyota never notified you of the issue? It might be worth the time and effort to try to get a partial or full reimbursed from Toyota since they failed to notify you. Sounds like you are just past the power train warranty.

I'd really bring it to their attention if I didn't get the notification. It may not do any good, but bet they would remember my name.

I did purchase the 84 month 100,000 mile power train warranty through Toyota. Those outside warranties have never provided any assistance when you need them. I am one who has a tendency to keep a vehicle long past the time the payments end.

As is the case with most 1/2 ton trucks, the late 5.7L Tundra uses a 10.5" semi-floating axle. Since the single outer axle bearings along with the axle shafts carry the weight of the rear of the truck (including cargo and/or pin/tongue weight of a trailer), these bearings are one of the weak links in this design.

Most 3/4 or 1-ton trucks use a full-floating rear axle as shown in the photo of the AAM 11.5" axle below.



In this full-floating design, the axle shaft does not carry any weight - the weight is carried by outer hub assemblies that each have an inner and outer hub bearing and attach to the axle housing tubes at each end of the axle housing. Each of the axle shafts only transmits torque from the differential to its respective hub. The full-floating hub arrangement is much more robust in terms of weight carrying capability due to its multiple larger bearings.

Just something to consider, especially with the higher pin weight that a 5th wheel RV design (versus a TT) applies to the rear axle of the truck.

By the way, $1600 to replace the rear axle bearings is WAY STEEP unless there's more to the story than a simple bearing replacement.

Good post, thx. This is a known problem with the '08 Tundra, and I don't think it towing related, as I am well under the limits. And, yes, in my haste I forgot to back out the cost of some other things I'm having done. So the cost of both bearing is closer to $1300.

BTW, truck is still not done and I'm not real happy with Precision Toyota here in Tucson.

I just joined si I know I might be a little late however I just purchased a 2014 Open Range Light Fifth Wheel 297 and I tow it with a 2008 Tundra crew max. Tows just fine even in the High Sierras, plenty of power. No squat but a little body roll so air bags solved that with only 20lbs of air, Im very impressed with the truck but time will tell.
