Some Wranglers can take on some normal wear by Mother Nature, especially if you live in northern climates with excessive snow/salt. Therefore, examining the under-carriage and frame of the Jeep for rust is critical. Rust is one of the easiest things to spot, but it's one of the hardest (possibly most expensive depending on much rust is presnet) things to fix. Some rust is normal and expected, but important components like lower shock mounts, which are usually a heavily rusted area, should not be structurally compromised with excessive rust, pitting or corrosion. In addition, areas like the control arm brackets and axles could have noticeable amounts of rust and should be examined carefully. Discoloration is fine and can be treated, but heavily pitted or corroded areas will need more extensive repair/replacement.

Just as exposed to the elements and road debris, you should examine the rest of the Jeep’s exterior. Paying special attention to the windshield frame, brackets, and hood for any chipped paint and exposed/rusted metal caused by weather or rock chips from the road. If the Jeep has painted fenders, the front face of the fenders can also be chipped, although these are more cosmetic issues and don’t pose as serious a structural concern as the windshield. They should still be examined. The side lower frame rail and body can also be exposed to road debris and often gets a significant amount of salt exposure if you live in northern snowy climates.

One of the exciting parts of owning a Jeep is the extensive amount of modifications available. If someone has built their Wrangler into the ultimate off-roading machine, its both good and bad for the buyer. One good thing about this is it may mean you will need to do less to get it ready for the trails. However you will have to pay extra because of the time and money they put into that Jeep. This also opens up the possibility of bad installation and modification of the Jeep’s structure. Some aftermarket bumpers require trimming of the frame rails. Ensuring the installation was properly done can be difficult to determine without the removal of the bumper, but a general attention to the condition of the bumper and how it currently sits can be indications of how well the install was handled. The same can be applied throughout other modifications on the Jeep. Differential covers that were not properly installed will have blacking along the seams, indicating leaking of gear oil. Usually the safest bet is to purchase a Wrangler that is as close to stock as possible, this reduces the amount of things that need to be checked over heavily and it allows you to build it up yourself exactly how you want it.

Aside from the overall numeric value of the mileage, it’s important to note the road conditions the Jeep was in during those miles. A Jeep can represent very low mileage under heavy off-road conditions, opposed to a Jeep with slightly more miles in pure paved road conditions. The difference is relative, given the driving performed and is an important factor to consider. A good indicator that a Jeep has been off-road extensively is the condition of the under carriage. If the factory skid plates and control arms show excessive scraping or damage, these could be signs the Jeep has seen a good amount trail time. Although these aren’t indicators its been abused, they are important points to make note of and consider in the overall price.

Keeping these five important point in mind when looking at used Wrangler should help with your overall decision on its value. It’s important to note that various owners complicate the overall history and could make it difficult to get an accurate assessment of the Jeep. Nonetheless, making note of the items described above will help guide you into the overall condition.
