Mine doesn't, but a co-workers '04 does all the time. Everytime I ride in it I wonder what the hell is going on.

 

My '99 used to have a shudder on deceleration at speeds 60 mph or higher. It was because of bad u-joints though. Almost all of the needles fell out and the joints werent moving smoothly.
I got 2 new u-joints at Autozone for $30 and now its silky smooth.

 

For what it's worth, here's what I just came across on https://www.f150online.com/forums/sh...d.php?t=274659:

well aint that a b****, i have the same problem, and i havent even done anythign yet. i thought it was plus or cop's or something.

 

It just started about 2 weeks ago. Mine shudders on acceleration from a dead stop, and only lasts for a few seconds, calling for an appointment now.

 

Thanks for the tsb info. I went camping last week and had the quad and camping gear in the back, about 1000lbs. I thought it was the tranny going out or my edge. I returned it to stock and it still did it.
I've had the quad in it before and it never did that until last week. It made for a less than enjoyable camping trip cause I was worried about the tranny.

 

I shudder everytime I see a Tundra

 

Dang thats what mine does at 60+ letting off I get a shudder or vibe, I checked my u joints for play but dont get any???

 

Mine does it. They've greased the slip yoke, replaced the driveshaft, installed a one and a two degree shim in the differential and it still vibrates.

 

How do I go about locating a "driveline shop" ??? I too get a shudder during take-off, but only when towing my travel trailer. I assume it's because of the pinion angle, which is caused from the tongue weight of my trailer. I'd love to get this fixed, but I wouldn't even know where to begin looking for a shop (besides the dealer, of course).

 

me too....I cringe! Copycat much Toyota? WTF??

 

I shudder everytime I see a fat chick in spandex.
