problem #1

Silverado 2500 LT 6.6L Duramax

  • Automatic transmission
  • 108,740 miles

Rear differential dripping oil at a slow rate. Taken to a shop and its $35 for the rear main seal, $450 for the rear slip yoke and an hour of labour to replace. Could have only replaced the rear main seal however there was a chance that the sloppy yoke could cause vibration leading to a leaking seal again. Don't cheap out. Could have done the job myself however it is very easy to wreck the main seal while you are replacing it due to the design and installation process. Lots of videos up on youtube for DIY'ers.
