I just recently added a Teraflex BB w/shocks and swaybar links and a BDS trackbar relocation bracket. I also added 305/70-16 BFG ko's and 8179 procomp wheels. I noticed the feel on the road after installing all of this was a little "drifty" and I seem to have picked up the feeling of the sideways "bounce" when you hit a rut. I figured the BDS bracket would solve the bounce problem.

I found out today I was running about 26 lbs. of air in the tires. I bumped it up to 32 psi and what a drastic change! The bounce is gone and the ride actually got smother. Handling and steering improved a lot. I guess I didn't think that the air pressure would make that much difference. Good reason to go out right now and check your air pressure!

 

I actually had a similar experience after adding my FT 2" BB. Having always run my BFG's at 32psi, I attributed the "wandering" road manners to the axles not being centered. So being a perfectionist, I ordered front and rear adjustable trackbars thinking it would solve the problem. It helped but not back to the way it was before the lift. Last Saturday I decided to add about 2 lbs to each corner and success. I guess it just goes to show, always try the obvious first.

 

Which is why when people recommend that one check their tire air pressure for these types of problems it is a good idea to actually listen.

 

Good point.

 

Has anyone tried using Nitrogen??? I had it in my tahoe and it increased my mileage a little bit, and it made a noticeable difference in the ride and handling. I haven't had it put in the tires on my JK yet, but I'm planning to.

 

I usually check my pressure about every two weeks. The issue I had was caused by the off centered axles after the lift. It didn't dawn on me that the pressure I was running before the lift would not be the same as after...kind of strange to me.

 

What's the advantage? Does it stay in longer than air?

 

Air is mostly nitrogen....about 78% Almost another ~ 21% is Oxygen. The rest is CO2 and weird crap, lke Krypton gas, and so forth.

Nitrogen gas is a diatomic molecule comprised of two nitrogen atoms, N2.

Nitrogen's atomic mass is roughly 14, so N2 is about 28.

Oxygen is another diatomic molecule, O2, of about an atomic mass of 16, so O2 gas is about a mass of 32...heavier than N2.

The marketing claims for N2 as a tire fill are almost completely snake oil.

It does expand and contract (Change PSI) like air, because air is MOSTLY N2 anyway.

It doesn't "Not leak out because its a bigger molecule" because, well, its a smaller molecule, and, because most air leaks from a tire are not on a molecular level anyway.

The PRIMARY advantage that you can get from using nitrogen is that its DRY....You COULD use DRY AIR and get the same benefit...but frankly, the water vapor might make a differece of a couple of PSI a month kind of thing in N2, or air....so using dry air, OR N2, is kind of like putting diapers on flies as far as solving a problem.

 

Good info, TEEJ! And thanks for the flashback to college chemistry!

I'm having a real hard time believing that nitrogen could have any effect on mileage, ride, or handling. Just can't quite wrap my little pea-brain around the concept.

 

"The problem has always been the fact that draught Guinness is (or should be) dispensed with a mixture of Nitrogen and CO2 gasses rather than the conventional CO2 alone. The nitrogen is used because it makes very fine bubbles while it is not absorbed into the brew as the CO2 is, thus it does not "over-carbonate" the beer. Also a special faucet is preferred which, in combination with the gasses, creates that wonderful creamy brown head which lasts to the bottom of the glass."

A much better use for nitrogen!
