Thanks. The video looked a bit scary to me. Lot's of disassembly involved, blind electrical connections, and all done with a nice creeper I don't wish to buy or store. I'll be looking to have the kit installed.
The additive top performer in your other linked video was Opti-Lube XPD. It would seem the same company offers a product called XL that is less expensive and offers even better lubricity. I expect I'll be purchasing some.
I can bring myself to mark a single post as the solution. You've all been extremely helpful.
