    Knocking on the rear end.

    Hello Jeepers,
    Has anyone experience knocking on first gear acceleration. It is not that loud but I can hear and feel it. I only hear the knocking sound when Accelerating from full stop. It is intermittent. It is smooth most of the time. My Jeep is about 3-4inch lift and has 35” tires. Any thoughts?

    My stock exhaust pipe started rattling / knocking somewhere towards the rear when I would start accelerating and then stop as I got up to speed. Couldn’t find out where it was making contact. It was definitely bent from impacts. Ripped in out and threw in a Dynomax exhaust. No more knocking sound.

About us
“wayoflife” is a moniker that I’ve been using for 20 years now and I chose it because I think it does a great job of explaining, in simple terms, the passion I have for Jeeps and the Jeep way of life. This is a lifestyle that transcends age, gender and race as the only thing you need to be a part of it is a love for the outdoors, a desire to explore, a yearning to take on a challenge and a will to conquer it. Over the years, Cindy and I have attempted to capture the essence of this lifestyle through photographs and videos and share it with others around the world. And, this is how WAYALIFE was born.
