Trouble with severe vibration 25-50 mph

He said it’s a new Adams shaft, I’d be shocked they messed that up, but it’s possible for sure.

I saw that too-

Doesn’t mean a cap was not dropped and needle bearing lost, cap not seated in yoke, Adams made a goof, shaft dropped and weight knocked off or someone messed with it ...

I’m pretty pro rear cv shaft these days on lifted rigs too, I’ve just had better luck.

My first thought is avoid driving it much til it’s sorted.
 
@Pert Near, I see where you say the pinion angle is "in spec" but don't see where you list the actual angle. What is that spec? Correct specs are often misunderstood and depend on the type of drive shaft you have. Because you said it's a new shaft from Adams I'm assuming that it is a double cardan shaft. If it is a double cardan shaft. your pinion needs to be nearly in-line with the drive shaft, 1-2 degrees lower is ideal. For example, if you drive shaft angle is 15 degrees your pinion should be set at 13-14 degrees. Based on your symptoms this sounds to me like and angle related vibration. I'm fairly confident that this means you need to adjust your pinion angle. If you measure the angles of your drive shaft and pinion then report back here with those measurements I can better advise you on your angles. Or, if you want to fully understand what the angles need to be and what type of shaft is right for which type of application, you can watch our video on the subject here

Shawn-

If this is not the thread we can start a new one-

But I wondered if you would share your driveline experience with us and answer these questions-

1. What is the number one mistake owners make installing Driveshafts

2. What is the most common problem with driveshafts that you see

3. Is there a sure fire way to tell if the shaft is out of balance versus pinion related

4. What are the elements of a good drive shaft

5. How often should a
drive shaft be serviced

6. Are greasable joints superior to non-greasable

7. What do you look for, personally, when evaluating a shaft

Thanks
Andy

Chris please move as you see best.
