Large rear axle, right side play

I looked for quite awhile for a thread that could answer this, but I'm an old man with bifocals anda dial up connection, and after about an hour of searching, I decided to ask my questions. If this has been answered before, and I upset anyone I appologize.

My 91 LX has considerable end play on the right side axle. The left side is fairly tight with a little end play, but the right axle moves outward by a good 3/4". Upon finding this out, I immediately stopped driving it.

I suspect the c clip on the right side axle is gone. Any thoughts?

In order to replace the c clip, is it necessary to remove the differential pinion shaft lock bolt and pinion shaft? Or are they accessible without removal?

The car is going into our shop in the fall for a complete make-over, and since I just got it a month ago, I'd like to fix it quick (if possible), and enjoy it while the weather is warm.

Thanks for any help you guys might offer.

Thanks Jamie. What you say makes a lot of sense. I know I should open up the rear first and check things out, but I have some time constraints this week, and need to get repair parts early this morning.

I was aware that there were issues with the clutches, since the LX would only spin one wheel, and do it without a whole lot of effort.

Thank you for your help, sir!
