    Thud at low speeds?

    2008 Rubicon JKU This may be hard to explain, but you can kind of hear it in the YouTube video. At low speeds (like idle to 5 mph low) my tires feel....stiff might be the word? It feels like one of them is a plastic Little Tykes. And when I'm going slow it almost feels crunchy and I can hear...

    Life after new ball joints and steering components

    So I've definitely been mis-aligned for a while with my JKU, just always had bigger fish to fry. Anyway, so I finally did ball joints. And because I'm high mileage and the fact that everything was already apart I went ahead and bought a new drag link and tie rod. I would hate to have to pay...

    Rubicon Sticker Location

    We had the hood painted and I forgot to measure where the hood decals go. Can anyone point me to dimensions or a template? This is for a 2008 JKU Rubicon if it matters.

    Low RPM Vibration Resonance

    2008 JKU with a 3.8L and 42RLE. I've read this from a couple different people but either people are terrible at updating their posts or they just never actually fix this. At around 700-900 RPM's I just get a pretty steady vibration throughout the vehicle, just like a low/deep vibe. It's more...

    What is this part?

    Did my radiator tonight. Not the worst job in the world, but I certainly have thoughts for those engineers at FCA. Anyway. 2008 Rubicon with a 3.8. This was actually wedged behind the overflow reservoir next to the electric fan housing. Is this the bottom half of an exhaust manifold heat shield?

    Ever wondered how much rust is under your sound / heat foam on the floorboard?

    Then it's your lucky day. Here's one data point. Truth be told, it's actually pretty solid quite a ways up there. But obviously with that surface rust forming and the rust inching that way up it was only a matter of time before it got there and ate it all up. The plan is to cut it out, get down...

    3.8 Exhaust Manifold Crack

    Last time I checked I don't think cracks were a design future of exhaust manifolds. 🤣 I have the cats removed for replacement and I thought I had an exhaust leak, so that's how I got here. Two questions then; 1) would any of you all try to weld repair this or do I just need to buy a new one...

    2008 JKU Rubi PID's??

    Hey all, I'm looking at a 2008 JKU Rubi Sport (edit: thanks to u/speartip for model clarification) tomorrow and there's speculation from the seller that the cats are bad. I'd like to monitor pre-cat O2 sensors to see if the engine itself is fine to get a feel for fuel burn independent of the...
