    Yeah 6nz cat, #### truck of SVD shortly there after I will lose all my air pressure. Definitely coming out of the hub, not the air line or fitting. So I assume clutch is shot and needs replaced?? Most likely original to truck with 800k. Already have new hub ready to throw on just wanted to double check with the smart guys. Thanks

    They are very simple in the internal design couple o rings,springs,a friction disk ,and a surface for to engage.I would assume one of the o rings is bad causing your air leak.

    I would bet its one of the o rings.replace the hub air leaks should be gone.I have rebuilt several of these hubs they are quite simple to rebuild and the rebuild kits had everything needed it was pretty well priced too

    Thanks, complete hub with pulleys and everything bolt in and go was 700 something and 600 core. Didn't get exact price on rebuild kit but he thought it was 450 and no warranty

    Yeah lester I think the last kit I bought at my peterbilt dealer was around $350 or $375 .The kit had everything bearings o rings air valve and clutch assembly.I think it took longer to remove and reinstall then it took to rebuild the hub.But im with you on the warranty
     
    lester Thanks this.
