I have a numb feeling in my little finger on left hand what would cause this

Always seek heath information from your doctor.
However, it sounds like a pinched nerve to me.

Standing in front of the truck. #1 cylinder is on the left front plug of the engine. Pull it out. Pull the coil wire off. Put your finger over the plug hole and have some one bump the engine until you start feeling compression. You can either check the balancer marks and turn it by hand to TDC or use a screw driver in the plug hole and turn it by hand until you feel the screw driver start to go down. Then you just passed TDC.

You will have to get under there and run your fingers across the line. Most likely that it has corroded in one spot and is dripping down the line. Not a tough job to do.

cv joints are covered with a plastic/rubber boot to keep the road dirt out and lubricating grease in''the inner works of a cv joint are an alloy metal with honeycomb chambers for the joint bearings to fit inside of..do this.. take your left hand and make a fist..then fit the fist into the spread open fingers of the right hand ..rotate both hands together back and forth..your ncv axle turns in much the same way..when dirt gets into the joint due to cover failure..this joint wears out because it has engine torque(twisting) pressure on it while moving..along with grit and dirt grinding away at both the metal and the bearings inside causing lots of slop in the joint..now if the engine torque becomes too strong for the worn out chambers in the joint, they will break..remember they arent steel,,they are alloy..thus rendering the joint unuseable ( slip your left hand inside the right between the fingers to grt the idea.. thats what the cv joint on your car is doing...so replacement is necessary..its not an easy job since most cars front suspension is opened up during this proceedure,,,car is ten years old do you feel that its worth the money? call for rates first...good luck and repost findings thnx

have your suspension checked .blown struts can cause steering issues

Try changing the flasher, usually in the fuse block under dash, it's round in shape. If you can't find it, put the left turn signal on, and listen for the clicking, that should lead you to it. When you find it, put your finger on it cause the hazard flasher is the same shape, when you feel a little vibration, you have the right one. If it still doesn't flash, it might be the turn signal switch in the steering column

If you are getting clouds of white smoke out the exhaust it is a good indicator of antifreeze getting into one or more of the cylinders. I bought a "Great" car sight unseen from a friend once and when he pulled in the drive the whole car disappeared in a cloud of white smoke that only left when he shut the engine off. I found head gasket leaks in half the cylinders. It takes very little coolant to cause the white smoke. If you are absolutely sure of zero coolant loss perhaps the smoke is a little blue--an indication of burning a little oil from a sloppy turbo bearing. Try the nose test-- it may give you the answer. Burning oil has a distinctive smell.
