My Truck Has Gotten Slower!!!!
I have a '05 QC that when I purchased used in '07 would run in the 13.50 - 13.70 range @ 103 mph @ 14,000 miles. Now at 20,000 miles the truck will only run in the 14.50 - 14.70 range and only @ 95 mph. This is the same vehicle that is starting to show some excessive bearing wear for the miles. Does anyone have an idea of what is happening?

What are the 60' times, curious if that is where you lost most of it.

Hmmm.... If you feel the tranny is OK I would get a compression test done on all cylinders. You can also try the typical tune up items, but at 20K miles I doubt that will equal 1+ seconds.

Problem Solved!!!
I followed the advice to check the rear end. I changed the fluid and replaced it with Royal Purple Rear Axle fluid and added the friction modifier. I then had the old fluid analysed. no proble with the differential. This week I went back to the track and the numbers are back on track!!!!! I guess old fluid can make that much of a difference!!!!
