hard start in morning sometimes have too cycle glow plugs 2-3 times to keep truck running

In the morning truck fires up easily howevere after i drive it for any length of time and shut the engine down it can take up to 15-30 seconds cranking to fire. Sometimes it will take multiple times 15-30 seconds cranking to actually start. When it does truck runs fine. Changed fuel filters put on computer no codes baffling

Check gauge

Diesel pick up was running fine. Al of a sudden it stop running. I noticed the oil has water in it. What could be the cause.

when ran and warmed up then shut off the truck wont restart till temp cools down it will crank. the trucks not over heating could it be exhaust the rear of exhaust is hotter than the front of ehaust is this normal

When I make a sharp left or right turn and accelerate there is a vibration that feels like is coming from reaend as if wheels are slipping or going over a washboard. Dealer didnt see a problem. Doesnt happen all the time but often.

brakes getting soft now

I live in Where cold should not be a factor. Upon 1st morning start up it runs VERY ruff for first 1/2 mile then no problems at all rest of day. I tavel alot. Only @ 1sty start up.
