Loud clanking sound from under my Jeep...
So, I have a 1999 Grand Cherokee Limited V8. Recently had some differential problems, so I have been lifting it up an awful lot. Not more than a month ago I replaced the front and rear right wheel bearings. That's how I found out about the differential. Drove it for about a month longer. The grinding got ridiculous so I decided to have the U-joints replaced then took it to shop for the big rear end rebuild. Problem is after lifting the damn thing a few times before having the rebuild a new sound started. It was a clanking from under the truck. It takes a certain amount of driving to get the clanking started and it seems to happen only when the gas pedal is not being pressed and I'm coasting. I told the shop about the sound prior to putting it in, but since the sound was only occasional they said that they could only work on what they knew was making the noise they heard. Today is Saturday. I'm obviously taking it back to them since the rebuild is guaranteed. That will be on Monday when they open back up. I'd appreciate some suggestions about what I should tell them to look at if they can't hear the sound. The sound is loud and hard enough that I can feel it in the pedal when I drive. Also, it only started after we lifted all four wheels to listen to the differential. BTW, the differential is fine now. And the truck has no engine problems. 180,000 miles.
