If its the two post hydraulic/cable lift then the adjustment is out and should be adjusted for safe operation. Without anything on the lift it should go up with only one "clunk" sound, if you hear two "clunks" as it goes past the locking slots then it needs adjusting.
On mine, I put the vehicle so that the hoist uprights are level with the middle of the front doors. I have the front arms (short ones) just on the bends of the chassis (there is a welded ridge in the right place. The rear arms goes just level with the front of the rear wheels (watch compressor on LH side and fuel tank on RH side) and it goes up perfectly. You take it up past a "clunk" and then let it down to lock so you can work on it.
I leave my suspension in normal position. When it comes down it is in Off-road position but a flick of the lever sorts it out.
