New to the forum, but been rebuilding XJ's for some time and just recently got as close to my dream MJ as I'm going to get.
Flying out of Alaska to pick it up in Colorado here in 2 months.
But between my XJ's and MJ's I have anywhere between 130k upwards of 300k without rebuilds.
The 4.0 if maintained can get 300k fairly regularly from my experience.
Ill say this....my Wranglers 3.6 ain't got nothing compared my 99XJ 4.0 when it comes to reliability amd being a work horse motor.
