It's a dampener that's on the front of the crankshaft. It has a rubber bushing built into it and I've seen them sling out and the ring get one sided and cause a vibration. It also has the belt pulley built into it.

Harmonic balancer would be more rpm dependant.

His, is speed dependant, so more like to be driveline.

duh....I should have known what harmonic balancer was....no...it does not vibrate when revving engine...front drive shaft meaning from section in front of carrier bearing..I would think it would have been checked. I will ask these questions tomorrow when I am there. I greatly appreciate everybody's responses. This had been a very frustrating. This unit only has 21,000 miles on it. We've used it very little in two years (1,000miles)because of this problem.

I'm with turbs, carrier bearing on the two piece rear shaft.

Explain the " front driveshaft "
As your rig is rear wheel drive.

Why or what are you meaning when you say " retube" the driveshaft?

What was the reason?
Did you damage it?
Is it out of balance?

Biggest question...
IS IT OUT OF PHASE?
You said it got worse, after they messed with it.

My advice, take it to another shop, tell them to install new driveshaft.
That one has been ruined, most likely.

as I understand...retube means replace the steel tubing between the end fittings because it was slightly bent....then balance. This assembly has a front and rear shafts with a carrier bearing in the middle. My understanding is they sent the entire assembly to a facility that was able to balance the entire assembly...but the vibration is even worse..I am invested at this repair facility because I have given them $2500 so far. So I'm trying to make then fix it so I can make good on my $2500 invested.

At this point if can find a solution through the experiences and (help)abilities of others, maybe I can help them find the problem. So, all suggestions/solutions are greatly appreciated.

I wonder what you hit to bend the driveshaft.

I still feel the issue is with the shaft,
As you say, it got worse after they " fixed" it.
