Hey guys. I have a question, and hopefully someone can help me resolve it. On my 7, when ever i put it in gear and let out the clutch, it will make a clunk noise coming from the rear end. I thought it could be the differential, or the Universal joint. I un bolted the U joint inspected it, and found nothing wrong. I also checked the differential to see if there was too much slack in it. It would only turn back and forth just a tad. I raised the rear end up(tires off ground) put it in gear and let out the cluch, and it would not make a noise. It only makes a clunk noise when it is under a load. It does not do it in reverse either.. And thoughts? Thanks!

 

thats your front diff mount. do a search and it'll come up with more details. its been covered quite a bit

 

The reason it doesn't make the clunk when its in the air is because there is not enough load on it to throw the rear-end up/down like when the whole weight of the vehicle is behind it.

It is most definately your front differential mount.

 

That was it! Thanks guys!
