rear axle dosen\'t work

I was driving along yesterday, and my rear end started clanking after I came off a stop. Now my drive shaft spins and nothing happens. My question is what could this be? I thank-you for the help. btw I have a 81 CJ-7 with a model 20 rear end

/wwwthreads_images/icons/tongue.gif What usually happens to the Model 20 is the splines on the wheel hub itself spin. Very common problem. It's time to do the one-piece axle upgrade/wwwthreads_images/icons/smile.gif.

Re: rear axle dosen\'t work

You know that poping sound you were getting for awhile when you backed up or started off? That was the axle hitting the key since the splines were striped. Like the other post said...you found the weak link on the AMC20. Don't waste money on a replacment 2 piece axle. For about $100 more ($300 total) you can put a set of 1 piece solid axles in and never have to worry about it again. My prefrence is Superior...they use a small spacer instead of shims...easy to set up and install. You can do it in about 1 day....including finding a shop to press the bearings on the drive shaft.

You know, I hear everyone talking about spacers and shims in 1 piece axles. The Moser axles I have in my CJ7 required neither, and they are priced in the same price range as the others. Seems to me simpler is better.

Re: rear axle dosen\'t work

/wwwthreads_images/icons/tongue.gif I've been meaning to ask you, Brad, about the BEARINGS in those axles. Are they something that you can dive into an industrial brg supply and buy over the counter? If I do this upgrade, I want something as common as dirt so I can fix it easy when I'm on the run from the feds after SUVs are made illegal by the new Gore-Feinstein administration./wwwthreads_images/icons/crazy.gif

Re: rear axle dosen\'t work

I have the earlys style Mosers (I was the 1st on my block with one piece axles), they use roller bearings that are available at most big bearing supply houses. THe newer ones use a common Timken style roller bearing. I could have my old ones machined to fit the Timkens, but then I'd be without the axles for awhile.

CJDave,

Get the Summers Bros. full floater rear axles. They take the same bearings and seals (except for the
small axle seal) as the front hubs on your CJ, you'll only have to carry the one spare set to fit any corner.
