Jeep Wrangler JK buying guide
The third-generation Wrangler, built from 2007 to 2018 in two-door and four-door Unlimited forms, with virtually all UK cars using the 2.8 CRD diesel and a minority the 3.8 or later 3.6 V6 petrol. It is a genuinely capable off-roader, and the checks centre on how hard it has been used.
The versions
- 2.8 CRD diesel: 174bhp, throughout production, manual or automatic
- 3.8 V6 petrol on early cars, automatic; 3.6 V6 petrol from 2011
- Two-door short wheelbase, or four-door long wheelbase Unlimited (the first four-door Wrangler)
- Removable hard-top
What to check on a JK Wrangler
3 model-specific things to look at when you view one. They're a starting point, not the full inspection.
Hard-top leaks and rust
What to look for: Feel the carpets and look along the roof seals and around the hard-top fixings for water marks. Look for rust where the hard-top meets the body and around its edges.
Why it matters: The hard-top is prone to leaks, and trapped water leads to rust. Damp carpets or water staining show where the seals need attention.
Dampers, ball joints and driveshaft gaiters
What to look for: Push down on each corner: it should rise once and settle. From underneath, look for oily dampers, torn rubber gaiters on the driveshafts and signs of heavy off-road use.
Why it matters: Wranglers are often used off-road, which wears dampers and ball joints. Torn driveshaft gaiters let dirt in and can damage the CV joints, so a split gaiter is best replaced before it does.
2.8 CRD cambelt and warning lights
What to look for: On a diesel, check the history for a cambelt change every 10 years or 125,000 miles. On the drive, check the ABS and traction warning lights go out and stay out, and try the Uconnect infotainment and the brake lights.
Why it matters: The 2.8 CRD's cambelt interval means early cars now need it on age alone. ABS and traction lights staying on, Uconnect glitches and, on early JKs, faulty brake lights have been reported.
