so today I took the car down to Mid-O and proceeded to lift it up with the air jacks...heard one hissing and the car slowly came down...popped it up again and same thing...When i checked the regulator i noticed it was at 450 PSI...wondering if I have blown the seals out of my jacks?

Where was it hissing from. Are you sure it was the jack itself or maybe is is one of the lines going to the jack. I had the same sort of issue with my old semi tube car. Took the jack apart and the seals are fairly common.

Ed, not John. just on his computer on the way back from Hershey.

Thanks, I will take a look tomorrow and tighten everything up.

Make sure jacks all lifting up fully when deflated - one might be still protruding a bit which would not be good in an off etc..

Funny you mention that...left rear was slightly down and get hooked on the trailer tailgate while I was loading it up....

We always look under the. Car after jacks are retracted to insure they are all the way up.
