Common Faults with the Jeep 4.7 V8 Engine The 4.7L V8 was used in several models from Jeep, including the Grand Cherokee, Commander, and Liberty variants (along with some Dodge trucks and SUVs).

Jeep JT Gladiator death wobble is an issue that can affect modified solid-axle Jeeps, particularly after suspension or steering changes. In many cases, it isn’t a single fault but a combination of worn components and altered geometry working together.

Jumping ahead to alignment or dampening solutions before checking basic wear items often leads to wasted time and mon

The Jeep Gladiator with the 3.6L petrol V6 shares a well-known weakness seen across several Jeep models in this engine family: the oil cooler assembly and its associated gasket can fail over time.

The JK Wrangler and the WK2 Grand Cherokee in the early days had a Pentastar 3.6 v6 engine which was known for developing a ticking noise.
