Hard clunk when put into drive

Noticed my xj makes a real loud clunk when I go from park to drive or from reverse to drive? Does anyone else's jeep do this?

sounds like you have a bad drive shaft u-joint.

you may also want to check your transmission mount. they tend to fail, especially if you have a leaker.

U joints are the culprit. Also make sure you're pressing in the brake hard enough.

Yup sounds right on the money.

Mine is getting louder

Need to isolate where the clunk is coming from. I thought I had a U-joint getting ready to go which would be common. But yesterday I noticed the clunk was louder when the rear diff was hot and the lube was thinner. Mine has 185k of pretty rough service on it and it looks like I am going to have to pull the cover and check the gear heel/toe mesh on this corporate axle.
