the sad thing is that the original post was a possible cure...and all I've heard was how "toyota needs to fix this" and "its not real "etc.....How many of you have actually tried to fix it YOURSELF?! You all sound like a bunch of welfare reciepiants wanting more govt handouts.Now go outside and try this....don't let em fool you the 2004 F150 had its own issus and people were hanging weights on the backside of the frames as dampers alco and the fleetside had a "wave " in the side metal as it went over bumps

.Oh hell ..you can't even pull the sparkplugs without them breaking off in the head...Fords better idea ...LOL.
