Went to use my QuickJacks to change to winter wheels this morning - they would, for the first time in 3 years, only lift my 992 by 2.5 inches.

I've loved my QuickJacks - have been repeatedly lifting a 993 and a 968 for over a year, no problems. And based on a quick Google - the 993 seems as though it is only slightly lighter than a 992 C2S (hundreds of lbs, ironically?).

I'm aware that the fulcrum movement requires a few inches to get leverage; however, these worked last year and the year before.

I've bled them again, ensured 40 lbs in the air cylinders (even though this helps with lowering not raising), have ensured the QJ oil tank is full, removed the ball bearings that I roll them around on for a little more space,and put my Front Axle Lift up to get some more space.

Any pointers? Guess I can run the 993 up on ramps first to try that.

 

Tried to run them up and down without the car?? Could have air trapped in the system somehow. If not, then a pump related issue.

 

I've bled them and didn't see/hear any air coming from the bleeder screws - so I have no idea what is going on. I guess i can try that again.

 

My 7000TL has less than an inch clearance when flat and it lifts the car no problem. Sounds like a pump related issue.

 

Give customer service a call..they're very good in answering these kinds of questions.

 

Did she gain some weight over Thanksgiving?

 

I had the same issue. 22 GTS. Car is to low for the QJ to get pressure to start the lift. drove the car up on 2x6's at all 4 wheels and QJ lifts great. What happened and what worked for me.

 

That doesn't sound right to me. My experience is that I have less than an inch clearance between the rubber block and the jack point and have never had a lifting problems.

 

If there is no air in the system, the seals may be bad in the cylinders or you have a bad pump. My money is bad pump.

 

Same here.

 

Ok - bled the cylinders again and even removed the extension hoses that I had added so it's back to the original config, nothing.

Then - I just removed the rear pucks and had the blocks touch the lift points directly (which I don't like as I don't always trust myself to line them up).

The extra 1" of space (there was already about 1/2") made the difference.

Dammit, what a waste of time.

 

Get a few 2x6s. You can use the pucks again.
