friends reg cab 4x4 97 shakes with just a light acceralation.can it be driveline ,mounts u joints ,it does it more and at loer speeds with a 6k
trailer

If it's an auto it could be the TC slipping.

 

its a nv4500 or 5 spd can the clutch slipping do this

 

Does it feel like the tires are out of balance? Or is it only under acceleration? It shouldn't be a clutch problem. Any white smoke, or is it in the drive line? I was thinking maybe check your fuel pressure.

 

it does it empty at 65 with light fuel applied
with trailer it shakes at 45 if you apply a lot of fuel it goes away
or back off and coast it goes away

truck is a friends and has 330k miles and drips oil alot
i wonder if something got oil soaked ,like a mount or something
the rear u joint was changed and it did not fix the shaking

If the suspension and transmission are ruled out, I would suspect dirty fuel injectors. The 12 valve injectors really should have the pop-off pressure increased by 15% or so to compensate for the lighter diesel we get now days, that will keep them cleaner longer and increase fuel economy and power back to pre-goofy diesel days.

 

Fuel injectors is a good guess and you can give it a good dose of PS diesel kleen to try and fix it. Another problem may be a bad pilot bearing; when mine went it usually shook when taking off though. cd

 

try checking the carrier bearing on the rear drive shaft.

 

ill tell him chk carrier and he added 370 injectors a while back i do not know if it did it prior
