Itís fairly simple,get the rubber cover off and thereís a ring holding the seal in,remove it and blow the seal out with air,it takes a lot of air and have it pointed into a bucket cause it comes out with a bang,I used a piece of pvc to drive the new seal back in,the problem is the oil is gone and thatís what keeps the air in,I was skeptical but CWN assured it would be fine.youtube has good instructions,donít count on Progressive to help,just google that part number,I think Amazon has them,I got mine out of Canada.
Thanks for the help...... I'm not sure if I want to tackle the job or not. I did receive an email back last night from Progressive in which I asked them the following questions;
1) How can I tell what the actual air shock part number is?
2) Does Progressive offer any instructions for rebuilding?
3) Do you carry the air lines, connectors, etc.?
Response from Progressive;
We offer a rebuild kit for 26.00 but we are out right now. You can do it yourself. If your shocks are out of the year warranty, we do not rebuild them any longer. For the airlines, we sell them, but there is about a month lead time right now.
If there is not a sticker on the shock with the part #, you will have to call CSC. I need the part # of the shock to give you the connectors, and tubing you need.
I have attached the instructions.
We do not have fitment for trailers, we sell CSC a private label shock, so give them the model of trailer to see if they offer it.
I'm a little concerned about part availability and/or shock replacement. I.M.O. it's a little odd to have everything on back order. I'm going to contact CSC for a response. Hopefully there is another shock out there for us CSC owner's for an alternative. If there is, I haven't heard of it. Personally, I wouldn't mind an adjustable shock without air.
