Hey "Stimpy",

Axle is not hard to replace, if you have tools & space. I'll try to list steps from memory here & others can correct as needed...

With car on jackstands/lift, remove rear wheel. Remove axle nut at wheel. Support differential & remove rear diff cover - WARNING! - Rear cover is what holds the diff in car! Make sure diff housing is supported well!

Next, remove axle retaining clip inside diff housing. Using brass drift, at wheel, tap axle in toward center of car; this will remove axle shaft at wheel ("collapses" CV onto splines of axle, if this makes sense). Then pull axle at diff side out towards wheel; axle should come free in your hands & drop down from car.

Good time to replace axle seals/CV boots/check CV condition/etc. Reverse procedure with new/used/reman'd axle assy & refill diff w/ proper lube.

I did mine in @ 1 hour - purchased used 300D axle from local MB salvage yard for $100 - WARNING!! - If you get a used axle assy, get the one for proper side of car; i.e., if left axle is bad, get salvage left axle, right for right. You want to keep them oriented in same rotational direction.
