I purchased a model XPR-10A 2 post lift, when the vehicle is on the lift it leans to one side. I called BendPak support and told them of the lean to one side. Without the tech investigating further I was told to put the arms together, “if their off, shim one side until their level”. I told him my posts were plumb and shimming them now would put them out of plumb and possibly mask another issue. I was told “an out of plumb post would be fine”. The tech told me I over tighten the base plate nuts when I mentioned I torqued them down to 95 ft lbs. When I mentioned the direction call for 95 ft lbs he said “oh, I guess its ok then”.

After ending our conversation I wasn’t comfortable with his plan for a fix so I called BendPak support again hoping to talk to another tech. I talked to tech named Tollman he seemed interested and helpful he asked me to take pictures of the arms together and send them to in for his boss to review. I was told he would call back later that day or the next day. When the next day came without a call I called BendPak again and was disconnected while talking to my third tech. It’s been two days I haven’t heard back from BenPak and thought I’d post asking for your thoughts.

Both posts are plumb when unloaded and loaded. While in the locked position the arm base is level, the arm extensions are not.

Looking at the pic the power side post is on the left and non-power side on right. This is the strange part, when loaded the non power side rear arm is 1-1/4” lower and the power side arm. The front non-power side arm is 3/4” lower then the power side front arm. When unloaded the both power side post’s arms are lower then the non-power side.

I’m ruling out the floor being uneven base on the plumb posts and level arm base. Also ruling out the cables because their sitting in the locked position.

Arm base is level.

Looks like you have screw pads, there.. ? What's the problem? Adjust the pads to compensate. Racks aren't perfect and neither is your floor.

I'm a professional tech and I work with a variety of racks with regularly. they pretty much all sag slightly from one side to the other. I adjust the pads accordingly and deal with it, otherwise. For teh most part, minor differences in levelness don't really matter at all.

Garage Journal, much like many other online automotive enthusiasts forums, tends to be populated by perfectionist engineer-types... and the truth of the matter is that the real world just doesn't work that way. Things might not look or measure perfect, but they sure as hell work! :) No worries, man!

LoL.. I got to agree with the comment about the engineer types wanting to overdo everything but... if you're a "professional tech" could you please point out the threads on the bottom of the pads that you see so we will all know why you ASSUME them to be the screw type ? Pssst, mr "professional" they ain't threaded... :lol_hitti Your post reminds me of those funny as hell posts people make where they call someone else stupid but they spell every other word wrong while doing it...

Are there 2 identical threads concerning this issue going on at the same time by the same guy ? Dude delete one of them you're confusing the issue with multiple threads...
