Hello, my tires slowly deflate and get pretty flat about every 4-5 days. I took it in to get the heater fixed and asked the dealer to look at it and see what it was. I was told I have 4 leaking hub valves and was given a quote of $922 to fix all four. My question is this, if I order the new parts and fix it myself, how difficult of a job will it be? I've never worked on a system like this, so I'm not even sure where to begin. I planned on researching it, but I would like to hear another person's thoughts on it. If you have any tipson how to fix it or if you think the quote I was given is fair. Thanks

 

Go to this web site and it tells you exactly how to repair your CTIS leak. It's not hard if you can turn a wrench!

Flash Off-Road Hummer Accessories, Hummer Maintenance, Modifications and Tech info is another good source of information.

 

Okay, great.

Thanks for the help.
