If it's a Sears jack I thought they are suppose to replace it if it falls apart?
I have a Craftsman jack that comes with a plastic case, good for taking to the track. But I do have to pump it quite a bit to get the car up. It's a 3.5 ton jack and 2 jack stands was around $50.
I will eventually get a better one from Sears for around $80 which felt real nice when I tried it in the store.
For a money is no object jack check out Griotsgarage.com and look at the all aluminum race jack they have. Some guy at one of the track events had it for his Ferrari. it was light and beutifull to look at and use!
I am still not sure about the jacking points on the WRX anybody know which spots are safe other than where the stock jack points are?
