September 15, 2010I have a rattling noise under my truck when I accelerate. The rattle doesn`t really sound like a U joint rattle, but still haven`t ruled that out either. I crawled under the truck and shook the drive shaft and everything seems to be pretty tight. The truck still drives great, but that noise is killing me because I can`t figure out what it is. Anyone have any ideas?

September 15, 2010It sounds like it`s an exhaust rattle of some kind.

September 15, 2010It only happens when I acccelerate because I can shift to neutral and let it coast and rev my engine with no noise. It`s more of a pinging and clicking noise, really more so than an actual rattle as I had posted before which makes me think that it may be something in the drive train.
September 16, 2010Found a loose exhaust clamp and tightened it up and that took out some of the rattle, but i also checked the drive shaft again, this time on level ground and found my front U-joint had play in it; so I guess I`ll be replacing my U-joints.
September 16, 2010I have a 2 piece drive shaft in my 99 extended cab. It did something similiar and it was the center bearing for the driveshaft. If you have the 2 piece drive shaft, look at that also. They do fail.
September 16, 2010I have a one piece drive shaft. My truck has over 196,000 miles on it and I service it myself on a regular basis. I had to replace the factory u-joints at about 50,000 miles, so I got pretty good use out of my current ones. I replaced the factory joints with grease able joints, but the only problem is that there is not enough room to get a grease gun to the grease fitting through the yoke, unless the drive shaft is in a certain position. I am replacing them this time with a more heavy duty joint that you don`t grease. They have synthetic lithium grease and have a lifetime warranty, so maybe they will last a good long time.
