New CB and u joints and still vibrations....Help!

Truck is stock 2008 TRD Sport 4WD 71k miles with rear leaf spring TSB.......I have a rumble strip shutter/vibration between 10-40 mph, let off or increase the accelerator and it goes away. Took it to my local mechanic who replaced CB (OEM) and u joints but vibration is still happening. I have read many great posts on this board but no real solution to the problem. Many with lift kits but my truck is stock.....love the truck and want to keep it or get a new Tacoma but this is a terrible problem.....Thanks for any advice

 

Tires need balancing?

 

Take it back to the mechanic and tell him he didn't fix the problem. If all he can do is randomly replace parts, then he should refund you the cost of labor for not fixing. Sounds like a bearing issue in your drive line. Check either the output bearing on the trans, or the diff for play.

 

Mine has the same problem, just left the dealership and they say that it's a rear tranny mount problem. There is a TSB out for it. Mine goes back in Monday to get it out on and I'll let you know if it fixes it. I also crawled under the truck and the mount didn't even look bad. Who knows.

 

Thanks for the info J Rod....will get that checked out! Let me know how it goes

 

I will let you know for sure. The bulletin is TSB-0249-12 if anyone was looking for it. They also said that if it doesn't fix it that the rear leafs would be next to be replaced. I don't see how that would be the case. I am also possibly leaning toward torque converter after doing some digging more. Sounds like the same problem the Tundra has and that the culprit for them.

 

Mount didn't do a damn thing other than add a burn to my arm from the exhaust when putting it in. Don't waste your time and money.

 

Thanks for the update....no surprise. It's a shame such a good truck has this problem, other than this vibration mine is awesome

 

Looks like you need to take it to a different mechanic for better diagnosis. Get your money back from the originial mechanic and take the truck to a suspension specialty shop or something like that.
