 i have had my truck into the shop 3 
times for a leak first they told me 
there was none 
then they said it was the rear seal 
then they told me the oil filter was 
not tight enough ... for 2 years 
i dont think so i think it is the oil 
pan which i will fix myself 
besides the bad experience with the 
machanic i like my truck , not sure i 
would buy from that dealership again
