  1. Front Differential Bearing Failure at 18,000 miles

    Earlier today I removed my front differential to install a Torsen carrier. Before pulling the differential out I knew that my pinion seal was leaking and my axle seals were weeping, but I had absolutely no noise and no reason to suspect a bearing failure. After pulling the seals out of the...
  2. CVF Titan V2 Intercooler Testing and Review

    Over the weekend I finally got the chance to install my new intercooler and do some testing. The high/low numbers posted below are what I saw when starting a few seconds before the WOT pull section of the datalogs and ending a few seconds after the WOT pull. Both WOT pulls were started in 2nd...
  3. Learning to Tune with HP Tuners

I did this because I wanted to determine if there were any...

Our trucks need to be put into brake maintenance mode anytime you...
  6. Programming 2nd PCM Using FDRS

    I recently ordered a second PCM for my truck so that I can send it off to HP tuners to have it unlocked for tuning. I have to program the module before sending it to HP tuners and I'm wondering if it's possible to have two PCMs programmed to the same truck that are essentially identical from a...
  7. IPC Code U3000:46 After OTA Update

    A few months back, I noticed some odd behavior from my IPC after an OTA update. The cluster works as intended for the most part, but the navigation directions that display in the IPC don't always work correctly and my off-road screen dissapeared. I scanned my truck and found code U3000:46-0A in...
