when jacking up a car a quandrant at a time, is that stressful on the car? Am thinking there is a fair amount of 'twisting' of the frame while the car is getting jacked up. I don't think it will cause severe damage for a typical time of ownership but nevertheless, can it cause the chassis to creak (make noise) or structurally weaken over time?

 

I wouldn't think so. Think about it, what you're stressing out the frame when you change a tire?

 

A little, but not so much that you should worry about it.

I doubt it, your car is subject to far worse "twisting" just driving on most roads and city streets, think about it, plus, most times you go over a driveway one wheel first, the car definitely twists under those conditions, and frequently!

 

disagree... - when these movements occur, it's at the suspension level with the parts that are supposed to be absorbing the shock (aka shocks), are doing their job. when you jack up the car, you are raising the car with approx 1/4 the car weight on one point of the frame that has no ability to adjust or compensate for this difference. i am also concerned with the creaking that occurs when i jack up the car. i believe these points are reinforced parts of the frame that expect a certain amount of weight. but that is one reason why i don't send my calipers off to get powdercoated (keeping brake dust away), because my car will have to be on jackstands. and that sound is just scary.

 

If you use the factory jacking points on your car, it should be fine, I understand your worry, but I have never had a problem with a car of mine, and I used to always have my cars on jack stands doing one thing or another, and every car has creaked when lifted! Oh, and why does powdercoating the calipers keep the brake dust away?

 

Why not use a floor jack and then install the front, and or rear, jack stands(or blocks under the wheels) in pairs if you're concerned?

 

I disagree with your disagreement.

To what do you think the shocks are connected? They're not out there just compressing and rebounding on their own.

You won't hurt a thing jacking one corner of the car up, putting it on jackstands, driving onto ramps, etc. The G35, like all cars and trucks today, are so torsionally stiff at the unibody (or frame in a pickup truck) level that you'd have to simultaneously yank one corner up and push the opposite corner down with thousands of pounds of differential force to do any damage.

 

Shodog: did you end up needing to roll your fenders when you added your drop?

 

wow - i forgot about this thread...

abq_g35 - powdercoating makes it easy to wipe brake dust away.

jkwright - fair enough... i always take it to a lift. i don't hear creaking.

 

where the heck do you people find lifts you can just use? I have asked every shop and mechanic in town and none of them can tell me about a place with lifts i can use or pay to use!!! ?!!?!?!?

 

on base. old military habit... they have these 'hobby shops' that let you take your own car and do your own work, and pay like $5 rental fee and tool use. they've got places for you to change your oil, every tool you can think of, and a lot of the time, someone is on staff to help you out, if you're clueless (like me). i don't know of anywhere else that would let you do this.

 

JasperG,
Seems a lot of these stalwarts are not prepared to pay the dues required to use on-base facilities!

 

Jasper: are these spots open to the public or only current and former military personel? are they on all military bases?

Thanks

 

Hey, thanks for the reminder, I had completely forgotten about the hobby shop on the air base here, kind of out of the way for me now, but I still may check it out again..........retired Navy.
