Hey guys I've got a 2003 Discovery with 130,000 miles. This morning I heard a clicking sound coming from what I thought was under the the shifter. The best way I would describe it was like a CD changer rapidly changing discs but it was clicking too.

The truck wasn't shifting hard and appeared to be running smoothly despite the sound. When I was driving I slowed to 25-20 mph when I heard the noise. I pulled over and waited for a minute, tried not to freak too much. I put it in the first gear to see if I would have the same problem and I didn't hear the noise again. I pulled over again and put in the drive and took it on back roads home. I didn't hear the noise again the rest of the way home. I had the transmission serviced in January. As far as I could tell I had the truck all the way in drive. Any ideas?

 

Help?

 

have you had the drive shaft rebuilt with greasable u joints? does the clicking increase with speed?

 

I haven't had that done in my ownership but it's something I've planned on doing. As far as I could tell the clicking doesn't increase with speed. Though I didn't go much faster than 35-40 mph. It sounds almost electronic in a weird way

 

well unless you want to destroy your truck i would get the drive shaft rebuilt first thing. without a better description of where the sound is coming from can't really help. if you want some good help take a video so we can hear the sound. prefferably next to a building wall so it echoes into the truck.

 

You suspect it's the driveshaft? What are the typical signs? I'll try to get a video up here.

 

typical signs are squeaking or clicking, soon followed by a harsh bang knock, shake, rubmble, loss of power, warning lights and heavy repair bills.

 

I second the front prop shaft.

 

You might want to get responsible for your truck and crawl under and see how many grease fitting you have on your front drive shaft.
I am always amazed how a person can not have a clue about what they are driving and what needs to be taken care of.
I would seriously suggest you "STOP" driving that truck as of now till you find out what is wrong or have it towed to a shop other then the dealer before you have a major failure.

 

Just took it out on the interstate going 70. Heard a huge knock and took out the transmission. Blew the motor too, thanks guys.
