What our local driveline shop does:

Install new ujoints
Inspect condition of yokes
Inspect runout (this is in the FSM)
Balance/time driveline (you'll see a weighted tab or two welded on)
Painted

$250

YES IT WAS SUPPOSED TO BE BALANCED before it even went out the door. Science happens, and did indeed give you said results. <img src="/forums/images/graemlins/evil.gif" alt="" />

If this bonehead won't replace your driveline AND pay for the collateral damage inflicted, BBB and your insurance company might be your next phone calls.

TAKE PICTURES--and with that being said, LOOK and make SURE you installed it correctly

Please read as reference

You might talk to a heavy equipment or performance shop if the guy doesn't make things right for you.

Be calm, and good luck! <img src="/forums/images/graemlins/cheers.gif" alt="" />
