Hey all, first time poster here. I drive a 2004 4.0 LJ with 32" or sumn tires and no lift yet (I'm in college and barely working currently). I am aware of some rubbing from the tires. What my issue has been is that on occasion when I will be making a tight turn, it will completely lock up on me, killing the engine BUT the radio is still on. This has happened once on the trail making a 3 point turn, once at a gas station causing me to almost have a head-on with the pump, and once more today when pulling into the parking lot for class. The drive home from class was fine. My power steering pump is not leaking nor is it sounding aggravated when I play with the steering. I was told it could have something to do with my steering stabilizer bracket (?) among other things.
If you all could drop a checklist for things for me to check that could be causing me this issue, it would be GREATLY appreciated! Oh, also, I have not gotten a single code throughout this happening. Thanks so much
Some other info on the jeep: recently over 130,000 miles so just changed plugs and fluids
I recently had the rear axle seal replaced idk how that could affect anything but thought it would be worth mentioning
Replaced IAC & TPS sensor aswell
