Almost lost the VX today, bad experience with Indy4x parts

[LittleBeast]

1st of all let me say that everytime I call Independent4x they are all very nice and offer as much help as they can.

However this time, their parts failed miserably. In the end it looks like their part was probably not faulty at all, rather the shop that did the install did something wrong.

Today I picked up my newly rebuilt and balanced rear drive shaft from the Drive Line shop here in Houston. The rebuild looked awesome new U-joints from Indy4x looked and felt great, HOWEVER I did notice that one of the 2 U-joints they sent me did not have the typical grease fitting on the cap but had a long shaft that was drilled into the middle of the U-joint and deposited grease in the middle of the joint. Major difference over OEM part, but I thought "I am sure they have tried these U-joints out on Isuzu's before they are probably fine". So I installed the driveshaft on the VX and took it out on a test drive. Everything seemed fine and then as I merged onto the highway I felt a shake in the driveline and then immediately a loud pop and bang and seconds later I am in the middle of the fast lane on the feeder to one of the most busy most traveled sections of a major highway in Houston with my driveshaft on the ground and that "different U-joint" from Independent4x blown up from the inside out, and cars racing past the VX just exiting the highway. The part just blew in half. Nothing was wrong with anything else, the driveshaft was professionally dynamically balance by the best drivetrain shop in Houston (and I paid for it) and the install was done by the book and with the ut-most care. The part just blew up the 1st and only time I accelerated with it installed.

I will be calling Indepedent4x tomorrow NOT a happy customer and NOT happy that my beloved VX is spending the night in a local parking lot.
