Reverse Clunk

[JS52]

Hey guys, new to the forum.

I did see 2-3 other post on this situation already but how loud is too loud or ignorable?

On cold start it clunks pretty loud when going from park to reverse. Even when warmed up it will be audible not as harsh.

Shifts fine otherwise and doesn’t do it again after it’s been driven or at operating temps.

Do you use the hand brake? I always used handbrake before released the brake pedal. No clunking from the parking paw.

i do, I always use the handbrake when it’s parked

Mine does almost exactly the same thing. Especially when cold and even when parked on a level surface in the garage overnight. When the jeep first starts up when cold, the revs are usually a little north of 1200 which is the way the engine tries to warm up. If I shift into reverse then, I get a pretty big clunk. I've taken to letting it warm up for a bit until the revs settle down. Usually I don't notice this once I get going for the day stopping at various places and the engine is still a little warm.

But on any inclines at all, I always set the brake first, make sure it is holding, and then shift into park. I do think the parking pawl is a little agressive! I also used to have an F150 that did the same thing and it turned out it was "normal" slop in the driveshaft/rear end.

Mine sound to be exactly what you described.
