Sorry for the late posting on what our step problem was.
Therefore the following, albeit late, refers and might offer some assistance to you:
Was told the cotter pin may have a tendency to drop out of the clevis pin in the linkage assembly (see attached diagram item 8 & 9). The clevis pin then comes loose, backs out and binds the step in either the closed or open position. That is what happened to our unit with 3500kms on the chassis, luckily in the closed position.
I was advised to remove this clevis pin and replace it with a stainless steel 2" x 1/4" bolt with a locking nut (photo attached) the motor would work once again without any issues. (
Note: I was then told by my service department not to use a Stainless Steel bolt because there would be incompatibility issues causing corrosion?).
I took ours Unity to the dealership service, and they replaced the two pins and not with the bolt and locking nut, even though they told me they had used a bolt and locking nut?
When I was in Winkler last month with my Unity, I spoke with LTV's service department and they said not to put a bolt in but just use another clevis pin and cotter pin
)
So you may wish to check your step to see if there is an issue. Apparently if you pull the fuse for the step when the step is half way extended (note: fuse is located in the battery compartment in the U24MB) one is then able to gain access and replace the problematic clevis pin and cotter pin before it comes loose and jams?
I just took my Unity to the service experts to deal with the problem; this was covered by LTV under warranty
Thanks also to NWBoater who assisted in providing me with some of this information and provided the photo of the bolt & clevis pin.
