#1620 of 3244 Air Suspension - Turn it Off? by dbc123 Nov 09, 2002 (5:46 pm)
I've never seen it in owners manual to turn off the air suspension while towing. The air suspension should NEVER be turned off when the car is driven. Only when hoisting the car or possibly when servicing the air suspension.

What model GM do you have? Does it have dual exhaust? What about black wall tires and and the upgrade wheels? You might want to make these upgrades. And tell your friends that your GM is the same "type" of car that most law enforcement agencies prefer. And if you don't have a rear sway bar, I highly recommend this as a safety and handling requirement. The change in front and rear stability is amazing.

"I've read that starting with the december production, some minor standard equipment is being taken off the CV, such as automatic parking brake release, and the pocket on the front of the bottom seat cushion, for example."   Well, it's either that or raised prices, which is better? Remember, inflation still exists.
#1623 of 3244 Keep the automatic brake release & cornering lights. by kinley Nov 13, 2002 (10:24 am)
Our TC has both & our TB has neither & they're missed on the TB. However, the TB does have a Tach.

I think they are just following GM's lead in decontenting their product. As long as they keep the functional items, like 4 wheel disc brakes, ABS, traction control (on the GM), etc.   While neither feature is an absolute necessity, they have already deleted the remote fuel filler release and other nice touches previously. I also think the base fabric has been downgraded.   They are still bargains, only makes one wonder what they are taking out that you cannot see.

Well, decontenting is widespread in the industry, even at H&T's "holy halls".
#1626 of 3244 tire pressure ftont and back by genex1 Nov 16, 2002 (1:27 pm)
Why does Mercury and nearly all other manufacturers recommend lower tire pressures for front tires. In the case of my GM it is 35 in back and 32 in front. I've been putting 35 in all 4 tires mostly because I don't understand why front and back pressures need to be different. Is it related to RWD drive?
#1627 of 3244 by rea98d Nov 16, 2002 (1:46 pm)
The higher the tire pressure, the harsher the ride. And since the front tires move side to side with the steering wheel (duh!) the softer you make the front tires, the less vibration translated into your arms. Thus, the pressure is cranked down a bit in the front tires to "absorb" some of the road vibrations.   The best thing for tire life, however, is to ignore the car maker's reccomendations, and fill your tires according to the tire maker's specifications. Of course, I just take the lazy man's approach and fill 'em all to 35, regardless of tire or car make.

rea98d Is it correct that you live in FIJI? Are they many CVs or GMs there?   Your point about front tire pressure would seem to apply to rear tires almost as well inasmuch as the rear tires usually follow the front tires over the road. If a softer ride is desired, it would make sense to lower the tire pressure in all 4 tires. I agree with you that it is probably just as well to keep all 4 tires at the same pressure. My guess is that result of differentiating front and rear pressures is not significant.
#1629 of 3244 by rea98d Nov 17, 2002 (11:56 am)
Nope, I live in Texas, they just didn't have a Texas flag on the list, and Fiji look cool, so...   As far as a softer ride, the reason (this being my theory. Ford Engineers may have other reasons) that the front tires are cranked down a little lower than the back is because the front tires are directly connected to the steering wheel, and the driver feels road vibrations through that. The back tires have no suce direct connection to the driver, and can have the pressure cranked up a bit higher without affecting ride quality as much. It's not a matter of keeping the front tires from shaking the whole car, the suspension can handle that, it's a matter of keeping the front tires from shaking the steering wheel, and dropping the air pressure just a bit, at least in theory, helps.
