Lippert has sent us 2 of these brackets to correct the "crowned" out arm (where the gear pack mounts). They are at our AL site, but I haven't seen them yet because we're at Morryde getting our IS installed.
Ours skipped, I dropped the gear pack resynched and still skipped. Broke down and called a mobile tech -he came and spent 2 hours to break a tooth on my gear pack. Sent him packing, replaced gear pack and used some interior slide slicks (not Lippert ones) tbat have faily thick grip foam on the underside, slide has worked well on this trip (w/o the service asembly installed yet). I think they are redusing the dip before the slide is fully in and holding the edge up a little higher which helps as the slide starts out (where it had skipped before). I also inserted cut washers as spacers (described in a Lippert field repair instruction) between the two wear guides and the crowned outer arm. Which probably also helped.
Will install the service assembly when we get back to AL and will post photo(s).
