Hello everyone I’m a first time Jeep owner and found this forum and figured it would help me with my 2021 Gladiator I got back in December of 2025.
About a couple weeks after purchasing it I noticed a fairly audible rattle coming from the driver side of the engine. It only make the noise around 3000-3500 rpm then goes away once I’m past those rpm’s. It also does it briefly when I left off the gas and let the truck coast. I’ve ruled out it being a roller/rocker issue because it would do it all the time if it were those parts and it would do it more consistently. The noise does not pop up under hard acceleration or when the engine is cold. My dad had a listen to it and said it sounds like a timing chain, guide, or tensioner issue. Truck drives fine, MPG’s are normal, no codes, no lights on dash. Jeep has almost 77k miles on it now and I bought it with 72k. Noise has not gotten worse
Just want to see if anyone here has had the same issue and how much it cost them to repair professionally or done themselves.
