Well after finally getting some time to work on the truck. I changed the fuel filter and it ran fine for a few minutes and started acting up again. I had a spare filter with me and put it on and still isn't running right. The pickup tube all the way to the lift pump is new less than 2 years old...

Check around the filter its dry.

I did check all the hubs they were all the same temepture. The oil did not smell like gear oil. It seems to start at the back side of the motor more towards the driver side

I just purchased a m925 with almost no oil leaks. On the 185 mile trip home I noticed oil on the rear tailgate and under carrage. Seems to be more to the drivers side. Both the oil and transmission are full. It also seemed to lose power in 1st gear and will no longer shift into 5th gear. And the...
