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...
Has anyone noticed a warp in the baseplates. Mine are not flat and warped toward the corners. They are off by at least 1/8" that seems a lot as I need to use at least two thick shims in certain anchor locations (which is 0.2in in thickness). Is this something to worry about?
As far as I can tell from the manual, the space between the posts is measured from the outside end to outside end of the baseplate. At least this is how it is indicated on page 14 of the manual.
Question in return:
I got my MaxJax and noticed that the baseplates on the columns are not flat...
