As a Cadillac tech for 25 years, I saw this same type of failure of the 6L50 trans output shaft to transfer case input shaft in CTS, STS & SRX all wheel drive cars starting in 2006 or 2007 with verying miles ( 20,000--60,000 ). The two came together, unlubed & open to the atmosphere, Michigan, moisture, oxygen, corrosion, failure. My wife wanted a 2008 SRX in 2009 so the first thing I did was onto the hoist it goes & Zep 2000 spray grease ( this sprays out very thin & fluid like then firms up & does not dry out, highly recommend ) into the top opening until poured out the bottom, 0-prob. for 90,000 miles then sold. Watch for the telltale signs of THE DUST. How you doing Doug. David R. Cook RV6A Rotary.

Subject: [FlyRotary] Eggie 3rd Generation PSRU failure again, etc.
One would have naturally thought that a "3rd Generation" PSRU would be the "cat's meow"; but that evidently isn't the case, and it almost cost a pilot and pax in an RV-9A their lives! The below report (see link) also states that there have been quite a few failures of this PSRU, and one came after only 160 hrs of usage! Amazing the "snake oil" that is out there and ready to hurt people...

I hope to get after the 13B FWF on my RV-9A this winter and have it ready for an engine run in Feb or March when it warms up a bit. This FWF package is the one that I bought from Tommy James back in 2005 or 6 (has it been that long ago?), and he flew it for 60 hrs or so in his Glastar. It is really time to get it finished up I think!
Fly safe out there!
