@Baron I bought a 17 Rebel with air suspension from a dealer. The front left corner was down a bit. The salesman said that’s the part they replaced. But I think they were throwing me a couple curve balls on some things. I can’t find this part in a parts blow up so I’m trying to find out exactly what it is before I call them out on it.
I expect I will pull it when the day comes that it gives trouble again. That seems to be the common approach. That part is a quick coupler fitting with a valve stem in the centre of each. When I get home I’ll do some searching on the truck and see if I can locate the part. I would have thought maybe more people would have chimed in on this but I’m new to the site and don’t know the lay of the land yet.
