    Today when I was taking the rear wheel of the car I noticed I have what I would consider excessive end play in the axle. I've tried doing searches on the forum here but the search engine just takes the first word of the query string, so that didn't work.

    If anyone has a suggestion as to the cause/cure or can direct me to a post that would be greatly appreciated.

    How much do you consider excessive? Pulling on the wheel makes it look much worse than pulling on the axle...

    Could be worn c-clips, worn clutches (if it's a posi) or nothing to worry about.

    thanks Holland. I had the wheel off the car, so I was moving the axle. It is a posi rear end. The only thing I can thing of that would allow movement in that system is a worn C clip, but one would think if it was that worn it would fall out.

    Worn clutches in the position will provide more space for lateral movement.

    There are also thicker c-clips you can buy to help take up space. Take off rear dif cover and measure between the end of axle and the cross pin in carrier. You can most likely fit a .175 c-clip in versus your stock .150 if there is that much clearance. There is a video from Tom differentials that states he prefers to take it down to .005 clearance between axle button and cross pin. I think factory specs are .008-.025 clearance.

    Is the seal leaking or look wet? The C clips should not just fall out B/C the Pinion shaft won't let it move in that far. I would hope not. I would pull the cover and check for any bits of metal. My Camaro had real bad tires when it got here so Air leaked out all the time in a couple days. The left rear would go flat and sometimes I let it sit for a week. The lube leaked out the seal. I know it needs a good over haul.

    In a case like this it is almost always worn clutches that cause the problem. You need to replace the clutches or shim them. Using a thicker c clip is just putting a band aid on the problem. Worn clutches also causes excess clearance in the differential gears, which will make them weaker.
