LOST JEEPS :: View topic - New Liberty Questions

There are 2 different tires that come on the Libertys (at least in '04 and I think this carried through), the SR-A and the ST. IIRC, the SR-A was an optional all-terrain tire and the ST was the standard all-weather tire. I know the SR-As I used to have had a max PSI of 35 and the dealer had them at 32; this was the right pressure for the vehicle/tire combo so I don't feel this could have been the problem with your older KJ.

The full throttle recommendation during the break-in period is to help set all the seals, rings, bearings, etc. You don't need to go to fast speeds during this acceleration, maybe just a quick jaunt from 20mph to 40mph a few times over the course of your break-in would do the trick.

The tow hooks total 3; 2 in the front, 1 in the back on the driver's side. You're not missing any. :wink:

Hope all this helps.

Thanks for all the tips. I'll be breaking it in on the way to one of my fishing holes today.

I thought of another question:
How soon should I wax the Jeep?
Do I need to do it right away or wait a few months, weeks, years?

My friends would freak out if they heard me ask that. My old truck actually had some kind of fungus growing on the hood because I never washed it. I also kicked the door shut all the time when my hands were full. That's one of the good things about having an old vehicle which is paid for and not worth much. Don't have to worry about a thing, and nobody would ever dream of stealing it. Now I guess I have to be a little more careful.

KW AV8R, they also use the GoodYear HP tires on the 17in rims which is what my Jeep came with.

I've found that the easiest (don't know if it's best) way, is to shift the tranny into neutral, then move to 4-LO. I usually just stop but, it will generally shift pretty easily doing anything less than 4mph. And yes, you can go from 2-HI to 4-LO without using 4-HI. Just make sure you're doing less than 5mph when shifting to 4-LO and never above 25 while in 4-LO.

Max psi means just that, MAX. The pressure in the tire should never go over the MAX psi.

I have the option that tells me the individual pressure in each tire and I must say its amazing how much the pressure changes given the environment.

When it was 20F outside, I had 36psi in the tires. A few weeks ago it warmed up to around 80F and I had 40psi in the tires. I stopped and took them back down to 36psi before I came home and on the 2hour trip home, they went back up to 38psi. Now that its cooled back down to 25F-50F, the tires have between 34-36psi..

You can safely run 33-36psi no problem.

My brand new 2007 Libby has Goodyear Wrangler St's. The strange thing is they say 44 max psi on the tire wall. Dealer had them at 37 psi. Door jam says max cold psi should be 33 psi. I'm confused. I thought the '07 I just traded in said 35psi on the tire.

The weird thing is I think I had different tires on the 2007 manual I just traded in. I thought they said 35 max psi on the old tires. The one's I have now say 44 max psi. I checked the pressure on my old ones and was running at about 31 psi which is where the dealer had them. Maybe they were way underinflated the whole time I had them. Maybe that's why I had so much trouble with the electronic throttle control on my manual....driving around on flat tires. My other questions: 1. When they say during engine break-in to cruise at 50 to 60, but to briefly go full throttle what exactly do they mean? Just press the pedal to the floor for a certain period of time and get up to high speeds? 2. I got tow hooks. I noticed on the rear there is only one, which is on the driver's side. Should there be another one? Just wondering.

The way I understand it with the break in, is to get on the throttle for high engine revving (not in low gears, maybe on the freeway) then suddenly get off the gas pedal. By getting off the gas pedal, the compression build up helps seal the rings? or something like that....good luck with your new auto...

I think you should vary speed w/ break in. and do varying acceleration too. I wouldn't floor it too much but once in a while

Break it in like you are going to drive it. I have had 9 new vehicles which I ran over 175,000 to 200,000 miles and never did anything different. When I bought the Liberty the dealer dropped it off at my house with 82 miles on it, I installed the hitch, hooked up to a 6 X 12 enclosed trailer fully loaded with tools etc. and moved 265 miles away running up to 75 on the interstates. I always change the oil the first time about 1500/2000 miles but other than that just run it. Of course dont be stupid and take it muddin and go full bore just common sense!

Now I guess I have to be a little more careful. You should be ok to wax it within a week or so after you get the Jeep. They bake the paint on from the factory, and its a possibility that its been sitting on the lot for a couple weeks. If you get a car painted at a body shop, its usually a good idea to wait at least a month to let the paint cure. KW AV8R, they also use the GoodYear HP tires on the 17in rims which is what my Jeep came with.

Just check the date it was made and make sure it is a couple months from that date before waxing it. I think 3 month is the ususal recommendation.

NEW QUESTIONS -When going into or out of 4-LOW is it ok to just bypass 4-WD HIGH and go from 2-WD to 4-LOW, or 4-LOW to 2-WD? -After shifting into 4-LOW do you have to stop before going back into "Drive", or can you shift into "Drive" while moving 2-3mph?

Just make sure you're doing less than 5mph when shifting to 4-LO and never above 25 while in 4-LO. I totally agree with this and I tend to shift to 4-Lo while creeping. Just make sure that you are not moving under power, are definately under 5mph (I'm generally under 1mph), and that the tranny is in neutral.

Actually sounds like the tires were replaced with a light truck tire vs. the passenger tires that come stock. May have been the same brand and size but, a different load rating, basically. I changed mine to the same size LT tire (different brand) right after i picked up my Libby and the max pressure changes are exactly what I had (33, stock and 44 with the LT tires) But, this is correct. Don't air down when the tires warm up.
