clunk when going into reverse

just like the title says im getting a clunk when shifting into reverse. sounds like its coming from the back of jeep. doesnt matter if its coming out of park or going from drive to reverse. had a gear swap last spring and this just started a few weeks ago. could the 2 be related?

Quite possibly, the clunk is slack in the drive train. Either DS or rearend. Inspect fully immediately.

No expert here but I would get the rear up with a floor jack and stands. Put it in N and get under it and try to roll the drive shaft in both directions. It shouldn't have much play or make any clunk sound. But its what I suspect you will find.

I doubt that its related to your gearing. If you've been running on the new gears since spring then they are probably fine.

08 2Door Red Rubicon. Rock Krawler 5.5 Longarm Coilover, Polly rear Coilovers. AEV hood & wheels, 37"KM2s, JE Reel 1350 shafts, 5.38 Yukon gears, Superior axles, Shrockworks stubby, Fab Fours rear, sPod, Rebel Offroad brakes, Warn winch and lots more.

U-joints could be the culprit.

I would place the trans in park and crawl under the jeep. Turn the DS by hand and see how much play is there. Look at the U-joints for excess movement. Also, there will be some movement of the pinion and ring gear due to the spider gears.

You can inspect the u-joints quick and easy. The action in the differential will be harder and I cannot put it into words. You will feel the ring gear backlash as well as the spider gears. With a light touch you can feel the difference between the two. There should not be any movement of the pinion in and out of the rearend.

Next, apply the parking brake and have some one shift the trans into gear while looking and listening. If there is a clunk and the DS does not move then you have trans issues.

If the DS moves and there is not an apparent u-joint issue then remove the differential cover for a closer look.
