I purchased a couple 100W LED flood lights from a popular ebay seller for my upcoming engine rebuild project.
I managed to disassemble the light and find inadequate contact between the aluminum PCB substrate and the case of the light which is used as a heatsink.
If you're thinking of buying these units, in my opinion they MUST be disassembled and repaired or they won't last very long, as hot spots develop on areas of the PCB and destroy the LEDs.
A closeup look at the inner tierod, usually hidden under the dust boot. This clearly shows why you need a special thin 32 mm wrench to remove the inner tierods.

Just a short wrap up on my three month long driveline overhaul project showing the engine reinstalled.
I had expected to release videos periodically throughout the project but couldn't find the time needed for editing. Instead I posted extremely detailed blog entries which can be read at:

I may eventually post videos focused on each phase of the project. Stay tuned.

After causing myself heartache on the right side of the car I changed gears and took a different approach on the left side. This turned out a lot better.
