more than likely you have a old thermal style actuator that went bad
try replacing the actuator, witch is located in the front end if you look under the truck there like 80 bucks but that's what keep my silverado from going into 4x4
You did not say what kind of vehicle it is. If it is a front wheel drive, it has drive axles and if the drive axle is going out, it will click especially when you turn the wheels.
It will be the 3ed spark plug from the front of the head going to the back on the driverside head.
No, There would not be a 4500 version of Silverado.
It will turn by hand, But not while going down the road.
sounds like a front wheel drive with bad cv joints, which are your drive shafts going to both front wheels.
You have 1 behind both front wheels. If you look close you will see an electrical wire going in towards the back of the rotors, That will be the wire going to the speed sensors.There is 1 screewed into the transfur case towards the rear of it, If it's a 4-wheel drive. If it's a 2-wheel drive then it will be screewed into the tail shaft housing on the back of the transmission were the driveshaft slides into the transmission.
The universal joints in the front driveshaft may be going bad.
Jack up the front end and check for play in the suspension. Check for looseness of the brake caliper. or try checking the outboard CV (Constant Velocity) Joint which is common in front wheel drive vehicles.
it might be your drive shaft or transmission going out.
how the hech is any one suppossed to know that???
the oil presser going up and down is why your check guadges light is coming on.. probly need a ned oil pump but check the sender first, much easer and cheeper to replace..
