I want to do a better job at putting the car on jackstands.
Haynes and clarks-garage.com suggest that one ought to raise the entire side of the car from the jack point on the rocker panel, and then position the stands at front and rear on that side. next, repeat on the other side to leave the car suspended entirely on four jack stands.
however - and Haynes/Clarks do not address this AFAIK - if only one end of the car needs work, I think only one end needs to be raised. If that is true, I think the above method generate stress across the car. Because if the car is then lowered with only one jack stand positioned at either rear or front, followed by another round of jacking and then putting another stand opposite, that would leave the car touching the ground by one tire at some point. plus the motion from the shocks, and moving up and down on the jackstand sounds like trouble.
one reason I ask is that I think I damaged my control arm by lifting and jacking only one side too many times. also I used the circular thing near the wheel well instead of the rocker panel lift point.

attaches to the whee. The lower control arms wear out at around 150K
miles and need new ball joints. Kits are available.

Clark's reports that a hockey puck is a useful cushion. there are also jack pads available I have seen.
however, it seems no such cushions are ever suggested to go between the jack stand and the car. my frame rail (I think it is called) is now dented and the urethane torn from all the use. is this simply a fundamental problem with supporting any car? seems to me that a cushion could be manufactured to fit perfectly between the 944 and any jackstand for additional support.

the aluminum suspension at the attachment points.

is it preferable to pull up the parking brake after positioning the jack stand?
the car lurches and creaks when I let the car down if I apply the P-brake before raising.
