Bottoming out over minor bumps

Hey Fellas

Tried the search functioning, but couldn't really find anything definitive. Can't really say when it started, but I've been noticing it more and more lately, going over a decent sized speed bump will cause me to "bottom out". Not sure if there is a better term for it, but you can definitely feel the a "thud" rather than the coils or shocks absorbing the bump. I tried taking a peek down at the shocks and struts, but I have no idea what I'm looking at.

I have a 2in zone BB thats maybe 3-4 years old. Springs don't look like they are sagging really. Any idea what the common issues are? Just looking for a place to start before I take it into the shop.

you're definitely not bottoming out...

have you checked your control arm mounts? I broke one on the axle once which was causing a thud...

I had a similar issue and I actually was bottoming out. The previous owner had a lift in the Jeep which they removed, but left the bump stop extensions in place. The jounces front and rear..well one rear jounce was missing, were basically touching the spring pad when the Jeep was level. I had zero up travel which caused a violent bang going over bumps.

I'd check for anything loose around there, and even take some pictures which might help others identify what is going on with it.

Pictures will definitely help. I'd say one of the front and rear bumpstops and front and rear shocks. And any more pictures you feel like taking will be appreciated

Also check the upper rear shock mounts. It's going to be hard to see them, but something could be screwy up there as well.

I see you live in FL, but you're a Giants fan..so maybe the Jeep used to be up here with all the road salt we got and could have rusted those upper shock mounts away. I had to deal with that last week also

Check Control Arm bushings. They can thump around when they wear out.

I'm very doubtful of them rusting away. Rusting solid, yes. My jeep had all 144k of the PO's miles in the north east, and I tacked on an extra 10k or so before I tried to swap the shocks.

I had a clunk acting up today. Turned out to be the lower shock mounts. Had the shocks off to cycle the suspension last weekend and put them back on with a bunch of antiseize. Bolts worked themselves a bit loose. Fixed it in the gas station with my channel locks. Tighten em back up.

This, too. I'd hope for shocks since they're relatively easy to break loose.
