I can say on my old Cherokee that I did see an improvement with a K&N filter. However, at ~$50 it will take ten or more tanks to pay for itself.
The factory recommended pressure for the stock 4x4 Liberty Sport, with 235/70/16 Goodyear’s is 33 lbs. But the BF Goodrich dealer said pressure should be at 45 lbs. however the ride is very “bouncy”.
Here's some info from sportcompactcarweb.com that was actually provided by BFG, so it applies. Remember this is pavement. Airing down is a good skill to learn for the dirt. But for best handling/mileage, something like this might be better:
In the event that you aren't able to find a recommendation for your car, or the tires on your car are so different from those that were originally fitted from the manufacturer as to be incomparable, we received the following rule of thumb from Oscar Pereda, an engineer for BFGoodrich. He calls it a "realistic starting point," saying it has never been just right, but is a good place to start. The rule is:
(Vehicle Weight in lb/100) + 2 psi at heavier end + 2 psi all around if suspension and alignment are stock.
Example: Stock 911, 3,000 lb.
(3000/100) = 30 psi
Add 2 psi all around = 32 psi
Add 2 psi to heavy end = 34 psi at rear
With modified suspension, the result is 30 psi front, 32 psi rear.
I would agree with the modified suspension comment. I ran 31 x 10.5 on my XJ, which was never available from the factory, in a BFG all-terrain KO. It sounds like the dealer just aired them to the max. Bring them down to 40, and start playing a little from there till the ride eases up. Your lift springs will break in a little too. Since they are a little higher rated in pressure than something like the stock Wranglers, I'd stay at or above the factory pressure unless on sand or rocks in the dirt.
Thanks!

Thanks!
We do not want to raise the vehicle because we must maintain a reasonable center of gravity for on-road travel, as well as off-road stability.
Any thoughts or ideas on this problem?
Thanks!!
Anyone one have and answer for installing cruise control in a 97 wrangler? Is there a computer upgrade that will except cruise? I know that part# 82204358 was discontinued. Is there a better way?

I'm about to go to 31x10.5 on my Unlimited and I'm going to post a question or two over there myself.
Does anyone know if it is possible to change out the 4.2L motor in a 1988 jeep wrangler with a 4.9L motor out of a 1997 ford f-150. If you have any information I would love to hear about it.
Thanks,
Other details...I have 76K miles on my 4.0 TJ, the 5sp manual, the standard NP231 T-case. I run 32X11.5R15 BFG mud terrains on Alcoa wheels and 33X10.5R15 BFG All Terrains on the stock wheels. No fender clearance issues, however they do rub the front sway bar at full lock (need to add a washer behind the steering stop bolt to eliminate that). I like 18 yr old scotch, Cohiba cigars and Jeep Jamborees. See ya out there.
The first shows the flywheel with continuous teeth apart from a small gap (missing one or two teeth)....
and the other shows a diagram of the face of the flywheel to indicate the teeth.....
can anyone clarify the number of teeth/number of missing teeth/position of teeth???? pleeeeease!!
Also, what happens to the instrument cluster when you change over to an aftermarket ECU???
Cheers

The other issue on a TJ Wrangler is alignment. Since it has a two piece tie rod that scissors as it is loaded and unloaded, it needs to be properly aligned after it is lifted. Not aligning it will cause two things, uneven tire wear that will cause vibration and it can cause what we call in the Jeep community the "death wobble" which is a violent shimmy at high speed that is undrivable and extremely damgerous. be sure to also check all bushings and tie rod ends for wear.
Since the rear driveshaft on a Wrangler is so short, drive line angle is critical (needs to be 10 degrees or less) when you do a lift. Vibration is common after lifting more than 2". This can be addressed in two ways, the first is the spacer they give you with most lift kits. This will work, sort of, but you will feel vibes at takeoff and low speed, deceleration and sometimes on the freeway. The proper way to do it, is to get a SYE (slip yoke eliminator) kit, this is a kit you buy that changes the tail shaft housing on your transfer case with a fixed u-joint yoke. The part that moves with your suspension is moved to the center of a replacement driveshaft. the kit can be had from a few good vendors. I would recommend Tom Woods Driveshafts or JE Reel. Some off road stores will install them, as will most driveline transmission shops or if you are a competent mechanic, you can do it yourself. The kits run a little under $500.

Buy a quality lift kit, get it aligned and get the driveshaft kit and you will enjoy your modified Jeep alot more than if you skip anything...
They do sell a 4" spring option and longer shocks as well.
I have also heard those 4" springs don't ride as nicely as the shorter springs.

Does anyone know if the RBQ head unit is compatible with the Kenwood Sirius Receiver. I'd like to avoid swapping out the head unit. I like the disc changer.
On a second note. If I do swap out the head units to the aftermarket Kenwood in my old car will the Steering wheel audio controls still work?
My XM receiver in my Jeep is a generic one, but I have an Alpine-specific 'adapter' interface that lets it work with my Alpine head unit with no problem. So perhaps check crutchfield.com to see what is available. They could probably help better.
As for the steering controls, if you go aftermarket on the HU, chances are the steering wheel audio controls will not work. Again I could be wrong, but if it WILL work, an adapter probably will not be cheap.
