187 , I got my seals at Memphis Equipment last year when I was at the convention in Huntsville . I Have a A3 so I changed everything over to the A2 setup , MUCH easier to repair over the CTIS seals . Not a bad job , once you burn off the air ring , I have lots of CTIS bearing if anybody needs some, LOL I did use GAA for packing the bearings , nice stuff , DO NOT FORGET THE CORK SEAL and I did use some HI-TEMP sealer on the cork also. I would also recommend a TIRE DOLLY , easy on the back , got mine at Northern Tool , plus a 3/4 " impact gun , had my trusty IR . When you get the wheels off you can rap a 6 ' nylon around the drum and use a engine crane to take the weight of the hub/drum setup , do not forget to loosen the brake adjusters before you try to remove the drums . It took about 2-3 hours a side for the rears . About a day in total for both rear axles . I got lucky with the brakes , gotta love the military , somebody JUST did a FULL brake overhaul just before it went to auction . bob k
