I just pulled out the 4 ton hydraulic jack from my Westy's storage cabinet
and tried to raise it.  It wouldn't work.  So, thinking the jack was old and
had lost its seals, I went out and bought another just like it from Ace
Hardware, and that new one performed exactly the same way..namely, it won't
lift the vehicle.  I'm glad I discovered this when it was in my own
driveway.  What is the proper jack for a Westy?  If it's a hydraulic, is 4
ton not enough?  Does Walmart or NAPA have something appropriate?

Thanks for any tips.
