The lug nuts take a 1.5" socket or tire tool. They spin real easy once they are loose.\nI will take a picture of and measure the spindle when home later today.

I had a few snap on my 73 270 that I used to have. Luckily local Truck Parts place had them.

I just looked up the torque specs for M500 chassis Lugnuts... 450-500 ft lbs! :shock: \n\nAlso - here is a pic of the spindle with measurments as made by me with a square and straight edge.

Thanks! I greatly appreciate it. \n\n450 to 500 foot pounds! Better start carrying one long tire iron! LOL.

The rear brakes seemed non-existent and I had a wheel cylinder leaking on the drivers side.\nIt was a real pain to bust loose the lugnuts with the factory tire tools. It is definetely not a job for light weights. (pun intended... I weigh 230 lbs) I had to use my entire body weight to loosen those lugs. ;) \nOnce I got the wheels off, it was apparent that the rear brakes haven't been making proper contact with the drums for some time. I pulled both wheel cylinders and took them down to my local NAPA. Mine are the 1 3/8" versions which cost $27 a piece. They had to order them from Houston and all parts will be here sometime this week. I also ordered a wheel bearing seal that turned out to cost $29 !\nWheel cylinder part numbers are:\nBendix\n33654 (1 3/8" Upper or Lower)\n33390 (1 1/2" Upper or Lower)\n -or-\nNAPA\nUP 37279 (1 3/8" Upper or Lower)\nUP 28661 (1 1/2" Upper or Lower)\n\n\nThe wheel seal is part # 48811-C1 This is for a Spicer 70HD rear axle in a M500 chassis.
\n\nWhat brand part# is that seal ?

Wheel seal that came out had part # 48811-C1 on it. NAPA gave me part # SKF 33136. I also found seal part # SKF 33136 on Rockauto.com.\nI know for a fact that the NAPA part fits because I installed one on the drivers side... I hope to get the Rockauto part in the mail today or tomorrow.\nThe NAPA cost me $29... I found a "closeout" seal on Rockauto for $6 but they have more for $20. The Napa seal was made in USA... not sure about the other one yet.

Done that a few times.\nHey I'm in a jam. I got mine ripped apart too. Were both your upper and lower wheel cyls the same ?\nBoth my upper and lower are 1 3/8 bore but the outside casting looks a little different. Which part # was right for you and did it fit upper and lower ?
