How high is too high?

Mar 06, 2005 11 Replies

If I am going to lift the front-end of my 93 Mustang GT by placing a floor jack under one of the lower A arms, how high (i.e., by measuring the distance from the ground to the bottom of the tire) can I lift the vehicle without causing any damage? (My intention is then to use the floor jack to raise the other side of the vehicle to a similar height.)



Thanks in advance...

I suspect MOST people, like me, lift the front by centering under the K member.

If you cant do that easily, get down to your discount tool store and buy a decent 3 ton floor jack.

In a pich, lifting one side then the other doesnt really HURT - but it doesnt help, either... esp when you might have developing floorpan/seatmount and floorpan to rockerpanel cracks.

Backyard Mechanic,

Thanks, again, for your frequent contributions to the NG and specifically for helping me out of a number of jams.

The reason for going the Lower A Arm route is whenever possible I use wooden blocks under the tires rather than jack stands in order to maximize the amount of room (or floor space) in which I can work and maneuver about and lifting by K Member requires me to lift the car much higher before the tires are lifted nine inches off the floor.

BTW... Regarding the floor jack, you once advised me to "Get a floor jack, stupid." Advice which I promptly followed. Needless to say, it has made my work much easier.

Thanks, again!

Well... thanks.

I understand the reasoning.

But you also need GOOD jackstands..(solid base) I place THESE under either the a-arms or body jack points, depending on the need.

DAMN BM! Someone actually listened to you!

Again, you are absolutely right!

...and I do... they are currently under the rear axle so I can rotate the drive shaft.

BM,

Come to think of it... were you the guy who suggested I use an unlit propane torch to find an electrical short in the engine compartment? ... or was it a vacuum leak? I can remember!

It was probably to help in finding a plug wire arc-over!

;)

Then you need more for the front. ;-)

Hey Steve:

That high enough for you?

With mine we have to pull her up on wooden blocks to get the floor jack under her, then jacked up one end at a time and pur jack stands underneath. This photo was taken when we did the aluminum drivesahaft a few years ago
