i have a bad shaking in my whole truck the front end is all new (ball joints, U joints, wheel bearing, and track bar and tie rods) the tires are balanced and rims are not bent, the axles aren't bent, everything that could be replaced has been, still shakes is it possible that it could be in the trans?? shaking starts at 60mph and up. out of ideas of what it could be all help would be great

 

Try rotating your tires and see if that changes it.

 

What kind of shape is your steering gear box in? I had terrible issues with death wobble in my last car (jeep grand cherokee)...after replacing all the front end parts with no success, I finally traced the problem all the way back to the steering box. Replaced the box, death wobble gone. The steering box in my truck also went bad - not for play or death wobble reasons, the output shaft seal failed in catastrophic fashion. Fluid pouring everywhere.

Check your steering box for play in the output shaft or any play in the steering wheel...they can be adjusted, but only up to a certain point. I'd recommend replacing it with either a borgeson new unit or a redhead rebuilt. I have the redhead rebuilt unit and it's super nice.

 

im sorry I forgot to add that the steering box was replaced and I rotated my tires and the wobble is still there, is it possible that it could be in the transmission?

 

Unlikely.

Where do you feel the shake the most? Thru the seat, or the steering wheel? Is it always present, or does it start up at some speed, and go away as you go faster?

 

Could be pinion angle. Unlikely unless you have done some rear suspension or axle work before it started

 

Try turning OD off and see if the shaking still occurs at higher speeds. If your plenum is not fixed, you may be experiencing a small misfire in the engine when in overdrive that is causing the whole front end to shake. This is an issue that has happened before on many occasions. For whatever reason, having the truck in overdrive amplifies the misfire and can cause a similar feeling to death wobble.

 

starts at about 60 and up and the whole truck shakes thru the sseat and the steering wheel, im doing a tune up so that should take care of any misfire in the truck, ive never had a misfiring problem but will look into it

 

Have you done any rear axle or supsenion work? Have you changed your rear drive shaft u joints?

 

the front suspension is all new and the rear end was rebuilt 4 months ago
