SOURCE: i have a 96

if the noise is only happening when you engage 4wd than most likely the issue is in the transfer case(the chain or bearings) or the front axle(bearings). i hope this helps

How do I fix my F150 Ford from squeaking on the front driver side.

It's your universal joints. Your universal joints have become warn and what's happening is as you accelerate its moving and the loose universal joints are moving which is causing the noise. It occurs at low speeds because of a slight wobble as speed increases the wobble goes away and so does the noise. It's best to change the font and back at the same time you can find them at your local part store starting at $19.99 each. As for your front end lubricate it real good. Hope this was helpful.

Front and rear diferential get realy hot

If you are driving it on dry pavement in 4x4 then that is completely normal as the driveline tends to bind up.

I have 2001 dodge ram 4x4. i get a thumping noise in the front end for about a quarter of a mile when its cold. it then goes away. it almost sounds like a flat tire. it seems to be getting worst. the tires...

there might be water in your tire frezing causing a vibration and goes away when warm might also be a broken belt in the tire best thing to do is go see a tire shop

2001 gmc sonoma 4 wheel drive slipping the lights on switch work goes into 4x4 but when you accelerate it slips out when you let off it goes back in any ideas?

Hello RD.
Yes, Inside your transfer case there is a clutch that is made up of several plates that are designed to slip when there is a difference in torque between the front and rear.
If improper type of fluid was put in or if the fluid levels were allowed to get low it may have caused damage.
If indeed that improper fluid was put in, drain and refill with the proper fluid.

I bought a tired 1994 gmc jimmy with a 4.3 vortec motor with 243,000 miles on it and just want to get more driving out of it. it is also 4wheel drive 1 problem i ,m having is that the oil pressure reads 40...

Do you have the electric shift 4wd? If so, start by checking if there is power to the actuator on the transfer case.

ok you hear a noise in the dash and a noise under the truck. there will be two noises under the truck one puts the transfer case into gear the other locks the fromt axle. raise rear axle let truck idle in 4x4 look under truck is front shaft moveing if yes the 4x4 motor on the front axle is not working remove dissasemble clean lube reinstall. if the shaft does not turn do this same procedure on the elec motor on trans case..good luck you can replace your oil pump it may help vehicle
Looking at the motor from the front, it is behind carb and to the right of the distributor. It has 3 wires on it.

When i am driving and get to 30 km/h it starts to sound like something is ratling, but when i switch to 4x4 it goes away and will stay away untill i switch back to two wheel drive.

sounds like the transfer case or front driveline has a loose component, it gets enough tension when in 4x4 to go silent, but loose enough to make noise when not in use. also look at front u-joints if in a pre-96 pickup/
