AMP Powersteps Hitting underside of cab on drivers side

So when I originally installed my kit I was missing the brake cable bracket that moves the parking brake cable up to keep it from hitting the arms of the steps. Everytime the steps would go up I would hear a thud under the cab which when looking at it was the arm hitting the brake cable splitter and the splitter hitting the frame. I finally got that bracket in and installed yesterday and come to find the noise is the very back of the step hitting the underside of the cab. When stepping back and squatting down looking at the steps, the very front of the steps under driver door has a slight gap from step to cab where the back of the step is touching the cab. Is this just a simple adjustment of loosening mounting bolts and sliding rear of step down or front of step up?

 

It is dark here now, but I will try to post pic tomorrow morning.

It's because the mounts aren't square to the body. There is a sequence you have to install them in. Now that you have them installed slightly loosen the Allen bolt and the 13mm bolt attaching the mounts to the body, LEAVE the step boards securely mounted to the mount arms. Open and close the door several times and this should get the mounts square. Retighten mount bolts and you should be good to go

+1 to bagged's suggestion and tightening sequence. I also struggled to get the step boards properly aligned and clamped at first installation because the arm mounts were off to the body. Let us know how it goes.

Thanks guys will do. I plan on trying this tomorrow morning. I'll let you know how it comes out.

No dice for me. I loosened up both mounts and let the steps deploy a few times then tightened them back up starting with the the bottom bolt and then the top one, same issue. It looks to me that both mounts are square to the body. I pulled the motor off and manually deployed and stowed the steps and there is no binding. It almost seems as if the motor wants to pull the steps in closer than it should.

I just installed mine a few days ago.

I noticed the same thing on both sides its closer to the body on the rear than the front.

Mine is such a small difference I will probably leave it be as I can't see it hurting anything.

I actually measured mine and the difference is just under half an inch on both of my steps

Going to try and install mine in the morning. Any tips?

I didn't install mine (local truck accessories store did), but I've seen where the troubleshooting guide in my post above helped with the sequence of installing/tightening the bolts. I did have to torque the bolts a few weeks after the install because the steps came loose and followed these steps. Check it out before installing...couldn't hurt..

Try loosening ALL the bolts (the ones that mount the brackets to the body AND the ones that mount the step to the bracket). Make them all finger-tight then run the steps a few times while you kneel down and watch them. You may have to "shimmy" things a little by pulling on the joints by hand. Do this a few times and you should be able to get the steps lined up correctly. Then go back and torque all the bolts to spec.

 

I did this on mine and it worked perfectly. I LOVE my Amp steps but the instructions should tell you to leave ALL the bolts loose until everything is operating then go back and torque them all at the end of the installation instead of torquing at each installation step.

Well, instead of starting a new thread, i'll bring this one back from the dead. Installed my AMP steps on my 16 All Terrain and the drivers side step is hitting on the backside of the cab. The front is fine, passenger side is fine, its only the driver side rear.

 

This is the 3rd set i've installed and the only issue that i've run across. Talked to AMP today and they told me to hose them out real good and lube them up. That would seem logical if they weren't deploying correctly, but it seems like the rear motor linkage is trying to pull it up to tight.

 

I just finished completely disassembling the driver side, checking alignment as mentioned here, and tightened to correct specs following their procedure and still have the same result.

Read my post above yours. Do NOT follow the Amp instructions that tell you what sequence to tighten everything down. Let everything loose and operate the steps a few times. After you get them aligned then tighten everything down.

 

If that doesn't work check to make sure the step itself isn't warped or bent. If the center of it is bowed down even a little bit that could make the rear of the board hit the cab.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Missing pieces of the Assembly   Detergency vs Solvency   Not the same thing. Detergency is the mechanism that surrounds solid particulates preventing amalgamation. Usually accompanied by a Dispersant whose job it is to keep those encapsulated particles in Suspension. Solvency keeps things that can be dissolved in solution.    Salt is a solid that can be dissolved. Pepper is a solid that cannot be dissolved. A detergent/dispersant is effective on pepper but a solvent is more effective on salt. As long as the solids remain in either state, dissolved or dispersed then they can be be removed with the oil upon change.    How many wranglers does it take to herd cats? Depends on how many cats your herding. How much sponge does it take to soak up water? How much water is there to soak up? Point is most oil blends start with some herding ability and next to zero sponge and recently even fewer wranglers are being sent to do the same job.    So you start with a dozen cowboys and zero cows but at the drive progresses you pick up cows along the way, but not cowboys. At some point you have more cows that the wranglers can handle and some leave the herd. Deposits. And the API has an acceptable number of cows they are willing to let loose. In the ideal world zero is the right number for he rancher but to the butcher....a few lost is fine. This cow is beat to death. Let's move on....   Solvency isn't something oils on the Walmart shelf care about AT ALL. Problem is, you motor does. Fuels driven varnish sticks rings and only a solvent can keep them in check. The bet is that the solids driven portion that plug the expander rings and the oil drain backs and VVT screens and AFM screens will be an issue long before varnish is. Not that it wont be but if they market well enough the consumer can be kept ignorant enough to either believe it is "normal" (A quart in 1 or 2K is normal) OR is kept at bay longer than the first owner is likely to hang on to the unit. Solvency cost money.    Now the OEM's have John Q. Public buffaloed into the belief that the number cows accumulated along the trail is a known and predictable CONSTANT. It isn't. Nor is the rate at which they crossed paths with them. Only the number of wrangles is constant. Or was. Each new generation of oil sees fewer and fewer of them.    So what happens when the number of cowboys is lower (lower TBN) with each seasons trail but the trial is longer (OCI) and the number of cows along that trail continues increase? (Conditions that promote deposits).    For awhile the blenders were on to something. Better bases are harder to degrade (fewer cows) but that was overtaken by a longer trail (OCI) and improved breeding (More cows) while continuing to reduce the cowboy staffing levels (TBN/Aniline #).    Marketing has been successful. We've fired most of the staff, cows breed line bunnies, the trail is ten times longer and we've convinced the boss his ranch is in better shape that it ever was.    That kids is just the cleaning side. The side few pay attention to.

      Looking for this part for my truck. They don't sell just that one piece and to get it you have to pay over $100 even used for the whole air tube. The piece the hose clamp snaps into that is held on by the screw and nut. If anyone has access to one please let me know.
