I know the manual says to lock the QL before jacking. I've done it both ways and can't see the difference. Obviously I wouldn't have the engine running so how could the the QL settle? My question is, what do people find best, locking or not locking and which QL setting is best.
Also, I do my own wheel rotations and have just about killed the tinny jack provided. What jacks have people found work best?
Bob, it's not necessarily settling... it's locking the QL in whatever position it happens to be in. The objective is to NOT have it try to level itself while you have it up on a jack. And it will attempt to do so even with the engine off.
Correct! Mine usually levels 10 to 15 minutes after pulling into my garage. This happened one day last week. A couple of hours later I unloaded five, 64 quart bags of garden soil. A short time later it leveled itself again.
Take the levelling thing seriously. I watched my QL go from offroad2 to normal height by itself 2-3minutes after shutting it off. We had a big discusdion on this or the other forum to gigure out what could have caused it. Never found a good answer. Disabling QL for jacking is a good idea.
QL is set up to level the vehicle after it's parked and shut off... for "appearance purposes" according to Jeep.
LOL...
"After the engine is turned off, it may be noticed that the air suspension system operates briefly, this is normal. The system is correcting the position of the vehicle to ensure a proper appearance."
I go into the settings and check jack mode. I beleive this disables the leveleing. After you put the car into gear, this automatically disables (unchecks itself).
I tore a 2 inch hole in a tire this weekend off-roading.
I disabled QL via uConnect setting and had it changed in no time, even used the scissor jack and a footer to a hi-lift jack to support the jack in the sandy location I was in.
The hi-lift would have been nicer of course, but the one available was locked securely in back of buddies jeep with no key. lol
I agree, I also need to get. At least the hi-lift footer as that really was helpful.
I still have stock tires, the Goodyear fortera, if I recall correctly. And the hole is in the sidewall, just caught a rock the wrong way while traversing the water hole.
Now looking at nitto terra grabber as replacements all around, or at least a tire spec'd for all terrain.
The Goodyear Fortera while touted as a 4WD tyre is still a passenger tyre meaning bulging sidewalls, not good for rocks. If you want to minimise this happening again then LT tyres, like the terra grabbers, is the way to go.
Let's say your go to your tire guy for a 4 wheel rotation. You disable the QL once you park, turn the vehicle off, go in the shop and wait. The technician comes out and starts the vehicle to drive it into the bay. Is the QL still "locked"?
