I'm a recent lurker and an XJ owner. I've decided after 6 years it's time to let the XJ pass to a family member. I've decided I want a KJ or KK to replace my beloved DD. Ive shopped a lot with lots of disappointments to finally find an 07 KJ with low miles and proof of maintenance. I did a test drive today and really liked it although coming from the 4.0 I was surprised to find the 3.7 lacking in acceleration.

Long story short while testing the 4wd, in 4hi things worked fine, but when I put it in 4lo it jerked hard with ANY acceleration. I understand how 4lo works mostly and yes I was on pavement (it was slightly gravely) but it felt like something was wrong. Is this normal? A 2nd XJ I briefly owned was 4wd and 4lo was rough but nothing like this. Just to be clear, it was loose pavement, no turns, gassed as light as possible but the jerk felt like it was slipping. I tried both dead stop from case neutral and idle roll from neutral. Any KJ owners have similar experiences?

Normal when on a high traction surface and the fact the '07 has throttle by wire system so it will always be a little jerky no matter what without a actual throttle cable.

You are just everywhere aren't you Lol. Thanks for the info.
