Something Blew Up...

[radiator]

Hello. today while accelerating onto the highway at about 65 MPH i felt a big clunk and then my truck started to shutter intensely. I then pulled to the side of the highway and checked the truck out. nothing was visibly wrong. i got back in the truck and the engine started with out a problem and it went into gear fine. so i started to drive it very slowly and when i got to about justover 15 MPH it started to shudder and clunk and wouldnt go any faster. What could be wrong? i suspect a transmission, torque converter or maybe a rear end problem.

 

Any suggestions would be greatly appreciated.

 

btw truck is a 93 Chev C1500 2WD 5.7L with 180,000 miles.

Forgot to mention that it is a 4 speed auto transmission (4L60-E)

well if its shifting fine i suspect the trans would be fine.could be bad universal joints or a rear problem

well it does go into first gear fine but i cant get it to go fast enough to see if it will shift into any other gear. i agree it might be the rear.

Okay found the problem. the rear u-joint destroyed itself pretty much chewing up part of the driveshaft. whew thats gonna save me alot of money lol...but leaves me with a question as to why it would fail. The u joint is only 2 years old with about 15,000 miles on it. i had no vibrations or noises prior to its destruction. i was pulling about 500 lbs of concrete in the back but i would think that that shouldnt cause it to fail.

exactly what i thought.

Thank you very much if it wasnt for you i wouldnt have checked it and i would have spent alot of money on towing and diagnosis at a repair shop.

Not a problem man.Thats what were hear for!

Did you regularly grease it? Stock ones are sealed, aftermarket joints are normally serviceable. Even if it hadn't been greased I still wouldn't think it would fail at 15k miles, but stranger things have happened.

Why did it happen?

 

No telling. But they do fail, it's not uncommon.

When replacing, make sure to get the greaseable units. And keep up on the maintainance. Should probably replace both while your doing the rear.

[radiator]

The old ones were not greaseable. Probably the reason they failed. I replaced both front and rear joints with new better quality greasable units.

 

Thanks for all of the help and great advice
