I just installed my maxjax today. I had the same uneven problem except it was primarily when the lift was going down. A little off on the way up and waaay off from one side to the other going down. Swapped hose sides and it didn't seem to change things. I also bled the system up and down, with and without load around 25 to 30 times. I plan on calling Dannmar on Monday to figure this out.

If silicone spray didnt do the trick I would give regular old grease a shot. Silicone spray seems to be finicky on some things and is way to light. I have seen it make things actually worse. Especially when the "load" is high. Silicone spray is way too viscous. Use a good heavy grease IMO. The fact that it is worse under load may be evidence of this.
It made my issues go away instantly. It may or may not be the same for you though.

I was certainly a candidate for one of these but after all of the problems that I have read about with uneven lifting, hoses and locks I think that I would just rather buy a known product without these issues. I kind of feel that this product might be over priced and under engineered in relationship to other products.
I remember when it first came out it had many false starts and actually was delayed many times. It sounds like it should be re examined. I know that COSTCO has them and that was somewhat comforting.

Do you take yours down every night or leave it out in the elements? I'm asking for one for Christmas since I have a regular man's garage and not one with 12+ feet of clearance.

I take the power unit back into the garage, and lower the lift arms to the ground. I then cover the columns with heavy duty garbage bags over the top and secure with a bungee cord. i dont want rain going down between the column steel and the blocks the cylinder rides in.
At the end of the season, i will unbolt it and wheel it into the garage for the winter.

The arms on one side of my new Maxjax is sometimes an inch lower that arms on the other side. Is ths acceptable? Gabe mentions a 1" tolerance, and the Maxjax manual seems tosay 1.5" is acceptable. Is this correct? Would other two-arm lifts have similar tolerances?
I have been bleeding the system without load, and expect to bleed it some more, I hope this will reduce the difference.

Hello Andy,
It sounds like your close to the tolerance and may want to try and move the car closer to the side lifting higher.. The Maxjax is a one of a kind lift that does not use equalizer cables to even out the two sides like your traditional twin post lift.. We feel the amount of complaints on the uneven lifting does not fuel a design change that would decrease its mobility. We also take pride in fixing these issues so give a call us or send me an e-mail and I will get you fixed up.. I have yet to meet a MaxJax I cant get up to speed..
Thanks as Always,
Gabe

I have had mine for about a year now ( LOVE IT 
)and mine also lifts a little uneven. Especially when lowering it as well. BUT you have to bear in mind that the columns are independant of each other and I doubt you could find two hydraulic cylinders that work at exactly the same speed very easily... As long as it works as designed and the car does not fall off it is of little concern to me. As Gabe said this is only way you could make anything like this do what it does... Just USE COMMON SENSE when using it and be thankfull that somebody FINALLY made something that does what this does!

Gabe, demoderby dave, thanks. The difference is down to less than 1/2", so I am assuming this is ok. I bled the cylinders again, this time with load. I lifted a Honda CRV on it today, and all seems well. I posted a photo in the the thread on Maxjax installs.

No such luck, demoderbydave. But, seriously, I set the garage up so I can enjoy working in it. I have never had a lift, so am excited about using the MaxJax. Funny, Les.

If you ever make it up to Massachusetts USA and want to "pimp my garage" let me know!!!
I just found this thread and forum. Been having the same problem.
One side starts lifting before the other side and is faster was getting a 2 inch difference at the top then they would balance out.
I was a bit nervous with a car up there and watching it level out.
Both lower at the same rate unitl they get close to the bottom the fast side would slow down and the other side would be on the ground, it would take a few additional seconds to
Talked with Gabe this afternoon. I swapped the hoses and the problem changed sides. The flow-divider seems to be the culprit.
Gabe is sending a replacement out
Thank You

I am having the same problem. Got the lift about a month ago and just finished installing it, so today I put my car on it and noticed one column lifting slower than the other. About 2inches when half way.
I have tried to bleed and bleed, but it doesn't have any impact. Neither do I see air come out of the bleeder screws, so I think the system is properly bled. I also swapped the hoses, and bled and bled again, no difference. So I don't believe it is the flow divider.
Another thing I noticed is that the slower column sometimes makes some strange noises right after the pump is stopped. I am not sure what that is, but it seems to be related to the hydraulics.
Any further advise appreciated.

pmgriphone,
Please try to move the car over closer to the side lifting faster, the side lifting slower has the heavier side of the car possibly.. When I test them here and I move the steel weight plates 1/4" it makes a difference.
If that does not work switch the hoses at the Cylinder and call us with the results and we will get it fixed for you..
Thanks as Always,
Gabe

My MaxJax Uneven Lifting With a Spasmodic Vibration
I love mine except its unpleasant problems.
The passenger side cylinder begins to lift earlier/runs faster than the passenger side one
every time with a car put on it.
**Cars keep to the left in Japan like in Uk.**
The right hand of my car is heavier than left hand becase of its east-west engine rayout.
So I tried to put my car on it slightly to the left to reduce height difference between both cylinders.
Have a look at this picture,
Here is comparison between right hand/driver side and
left hand/passenger side.
Passenger side is approx 2" higher than driver side around half way position.
Released hydraulics to let both arms go down to the safety bars inserted.
Passenger side arm touched the bar a few seconds later than drivers side one.
Driver side cylinder could be shaken because it had quickly shrunk and released hydraulics sooner thanpassenger side one,see this video below.
Video at
Then I raised it to top position.
I think it must be dangerous to raise from the bottom to the top at one push unless doing that because mine cannot hoist a car evenly.
Driver side cylinder is approx 1-7/8"lower than top position where the passenger side one has just arrived.
In this reason,the hydraulic pump must be kept operated,though the passenger side arm is
already pushing the stopper up to make the driver side arm arrive at top position.
Recently the height difference between both cylinders gradually seems to be larger and larger.
In addition,a spasmodic vibration occurred on passenger side cylinder while moving from half way to top.
Video at
waved surface of grease derived from this vibration
Also this unpleasant judder can be seen in lowering the car slowly from top to half way.
It bothers me a lot and make me feel anxious if the car would be fallen down.
Video at
To Fix Uneven Lifting?
I tried to remove the safety bar of passenger side as an experiment and release a little bit of hydraulics
to make passenger side cylinder temporarily shorter than driver side one and
the car leaned to the left(passenger side) .
Operated the hydraulic pump to raise both arms to exceed top position again
and bled both cylinders and small amount of air came out from driver side one,then inserted
both safety bars and released hydraulics.
After doing this mine raise/lower slightly evenly but several times of operations up and down
finally ended up uneven lifting with spasmodic vibration again lol
Is there anyone who has MaxJax with judder like this?
uneven lifting ,lowering my car
btw,there can not be seen these ugly phenomena unless a car is loaded on this lift.
Next holiday I'm going to crisscross the hoses
to test the flow divider.

To fix the vibration get some of the Cat anti-chatter.

That is the one you want. I think I used 1/2 if that bottle. No more chatter after that.

Just Crisscrossed Hoses
My friend an owner of MaxJax in Japan suggeted
"Just crisscross hoses in order to fix uneven lifting,
it may improve this height difference,and I've no idea for
improving vibration problem,anyway just try it"so I did it.
This time the car is lifted almost even ,though previously
it leaned to the right significantly.
Also its spasmodic vibration has gone,through several times of
lifting or lowering.
I can not understand what comes this result,with which I'm satisfied.
I'm going to try unti-chatter if chatter will appear on my MaxJax next time.

I wanted to let you guys know how I solved my uneven lifting. My maxjax has had the uneven lifting since I got it. I have done several sessions of bleeding but never got it to be even. It was off as much as 2.5 inches. In the past I would stop at each level and let it down on the safety bars to get it more level as I went up but was a pain in the ***.
I installed a flow control valve today on the side that was lifting high. After I did that I did several sessions of bleeding then lifted it up and down adjusting the flow each time until I got them even. It now lifts within .25" of each other. I used a laser level to measure the height during the adjustment. Could not be happier. I used the flow control valve and 1 3/8 ******. The valve I used is:
http://m.globalindustrial.com/m/p/t...amic-jp-fc-micrometer-adjustment-knob-3-8-npt
I think the folks at dannmar have tested these for the uneven lifting. I can say it fixed mine and was the best $30 I have spent.

By the way,do you know where to buy the additive?
I couldn't find any webstore that can send such lubricants to overseas.

I found it at the local CAT dealership. Not sure if they have CAT dealers in Japan. If not maybe you can find a place to ship it.

Hi guys been reading all these threads about uneven lifting. One quick question...is the low side mostly the one that has air in the system? Or could it be the side that's lifting higher as well and needs to be equally bled? Sorry if this is a silly question and also sorry about bringing back such an old thread....thank you as always!

Going to try this out; my lift only raises unevenly when there is a vehicle loaded. Could you give me any insight on how you did this Steve?

I too am having chatter and uneven lifting.
Did you add this to the hydraulic fluid?
Thanks!
