when i pull out in the level it doesnt really to anything but if the ground is alittle up hill and not much up hill either and when i release the clutch and go to pull out the whole frontend shakes and jumps up and down alot .
i have and ideal what this is but i want to know what you think . and the truck has 17,000 miles and the rear main seal seams to be leaking alittle but not much . and it seems to me that the clutch is real easy to push in with my foot . and it seams to act worse the more i rev the engine when i pull out .
