Axle Nut Problems
Posted 13 September 2012 - 08:50 AM
I have two questions. First, what would cause/allow it to come loose like that? Second, am I going to have to go to the junkyard to find the washers (flat and conical)? Unfortunately, the road it came off on it one of the busiest East/West roads in Colorado Springs, so I can't just go looking across three lanes off traffic to find the one that came off.

So you are actually shearing the cotter pin as well? I am not an expert but if you can you should make sure that the spring washer is OEM and not some flat washer from wherever. The conical washer needs that outer ring support to properly torque the hub. Were these flat washers?

Just an after thought (don't mind me, but I have to ask), you are tightening the axle nut to the torque setting after you have the suspension back on the ground. I tighten it when it's still in the air to a reasonable torque and then let the car down, and re-tighten to the 140 number.

@edrach, I tightend it after it was on the ground, put a little extra since I was retightening it, then turned it tighter till the holes for the pin lined up. I snugged it in the air, torqued it on the ground, put a temp pin in it, test drove it to make sure it had fixed the noise, rechecked the torque, then put a nice beefy cotter pin in it.
I've never had an issue like this on my '87, I've had other issues, mostly engine, but never any touble aside from wearing the axle boots out. I'm gonna have it towed down to the shop, see if I can see something in the air that isn't as evident on jackstands.
