My truck started making a bump noise driving home from work today and I could feel it underneath in the middle of the truck. It did it every one-two minutes. It has never done it before. What is it?
It has never done this before and now I am scared to drive it thinking something underneath in the middle is going to break in half or something
Re: My truck started making a bump noise driving home...
Look under truck and see if anything is wrapped around drive shaft also if looks good u joints may be going bad also check the center bearing and bracket its a support hanger bearing for driveshaft

U joint their part of the drive shaft assembly lets it move up and down when you go over a bump
Makes a scarry noise when they are bad but they are cheap 10 bucks a peice and as long as you don't drive it for ever it won't fail tomarrow but get if fixed soon .
Not sure but, put it in the air and try turning the input on the front axle. I'm thinking there's something wrong with it which would explain why the drive shaft was removed by the previous owner.
remove the thermostat and place in a pan of water a boil and wait to see if the thermostat opens , as for the noise , get the thermostat sorted out and see if still makes the noise , could just have been caused by the overheating, one thing at a time so you know what the problem is
Make sure your battery is secured by a good battery hold-down system...if the battery shifts in the tray and the positive terminal touches the fender, the dead short will immediately kill the vehicle.
Also, take the alternator to a parts store and have it tested if your battery is held down firmly. The whining noise can be bad alternator bearings. On a vehicle of this vintage, this is a possibility for the noise. It is furthermore possible that the alternator has died electrically, and during a lengthy drive, the vehicle's own electrical consumption will drain the battery and the vehicle will die en route.
When you jump it off, it gets enough charge from the donor vehicle to drive, but if the alternator is dead, it can't keep the vehicle supplied with enough energy to operate.
There are a few suspension parts that can cause knocking noises. Such as swar bar loose, strut mounts going bad. You should really have a shop do a complete suspension check.
